The FTC Technology Team welcomes suggestions for improvements to core software, ideas for new features, requests for built-in support of new sensors, and well written bug reports. - -## How can I contribute? - -### Pull requests - -__STOP!__ If you are new to git, do not understand the mechanics of forks, branches, and pulls, if what you just read is confusing, __do not__ push this button. Most likely it won't do what you think it will. - -![Pull Button](../doc/media/PullRequest.PNG) - -If you are looking at this button then you've pushed some changes to your team's fork of ftctechnh/ftc_app. Congratulations! You are almost certainly finished. - -The vast majority of pull requests seen on the ftctechnh/ftc_app repository are not intended to be merged into the official SDK. Team software is just that, your team's. It's specific to the tasks you are trying to accomplish, the testing you are doing, and goals your team has. You don't want that pushed into the official SDK. - -If what you've read so far makes little sense, there are some very good git learning resources online. -[Git Book](https://git-scm.com/book/en/v2) -[Interactive Git Tutorial](https://try.github.io) - -### Guidlines for experienced GIT users. - -If you are absolutely certain that you want to push the big green button above, read on. Otherwise back _slowly away from keyboard_. - -The real intent for advanced users is often to issue a pull request from the [branch](https://www.atlassian.com/git/tutorials/using-branches/git-branch) on a local fork back to master on either the same local fork or a child of the team fork and not on the parent ftctechnh/ftc_app. See [Creating a Pull Request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/). - -If that is indeed the intent, then you can merge your [topic branch](https://git-scm.com/book/en/v2/Git-Branching-Branching-Workflows#Topic-Branches) into master locally by hand before pushing it up to github, or if you want a pull request for pulls between branches on the same repository because, say, you want team members to look at your software before merging into master, you can select the base fork from the dropdown on the "Open a pull request" page and select your team repo instead of ftctechnh's. - -Alternatively, if you have a team repository forked from ftctechnh/ftc_app, and then team members individually fork from your team repository, then pull requests from the individual team member's forks will have the main team repository automatically selected as the base fork for the pull. And you won't inadvertently request to pull your team software into ftctechnh's repository. - -The latter would be the "best" way to manage software among a large team. But as with all things git there are many options. - -Pull requests that do not fall into the category above are evaluated by the FTC Technology Team on a case-by-case basis. Please note however that the deployment model of the SDK does not support direct pulls into ftctechnh/ftc_app. - -### Report bugs - -This section guides you through filing a bug report. The better the report the more likely it is to be root caused and fixed. Please refrain from feature requests or software enhancements when opening new issues. See Suggesting Enhancements below. - -#### Before submitting a bug report - -- Check the [forums](http://ftcforum.firstinspires.org/forum.php) to see if someone else has run into the problem and whether there is an official solution that doesn't require a new SDK. - -- Perform a search of current [issues](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues) to see if the problem has already been reported. If so, add a comment to the existing issue instead of creating a new one. - -#### How Do I Submit A (Good) Bug Report? - -Bugs are tracked as GitHub issues. Create an issue on ftctechnh/ftc_app and provide the following information. -Explain the problem and include additional details to help maintainers reproduce the problem: - -- Use a clear and descriptive title for the issue to identify the problem. - -- Describe the exact steps which reproduce the problem in as many details as possible. - -- Provide specific examples to demonstrate the steps. - -- Describe the behavior you observed after following the steps and point out what exactly is the problem with that behavior. Explain which behavior you expected to see instead and why. If applicable, include screenshots which show you following the described steps and clearly demonstrate the problem. - -- If you're reporting that the RobotController crashed, include the logfile with a stack trace of the crash. [Example of good bug report with stack trace](https://github.com/ftctechnh/ftc_app/issues/224) - -- If the problem wasn't triggered by a specific action, describe what you were doing before the problem happened and share more information using the guidelines below. - -### Suggesting Enhancements - -FIRST volunteers are awesome. You all have great ideas and we want to hear them. - -Enhancements should be broadly applicable to a large majority of teams, should not force teams to change their workflow, and should provide real value to the mission of FIRST as it relates to engaging youth in engineering activities. - -The best way to get momentum behind new features is to post a description of your idea in the discussions section of this repository. Build community support for it. The FTC Technology Team monitors the discussions. We'll hear you and if there's a large enough call for the feature it's very likely to get put on the list for a future release. diff --git a/.github/PULL_REQUEST_TEMPLATE.md b/.github/PULL_REQUEST_TEMPLATE.md deleted file mode 100644 index 665369b..0000000 --- a/.github/PULL_REQUEST_TEMPLATE.md +++ /dev/null @@ -1 +0,0 @@ -Before issuing a pull request, please see the contributing page. diff --git a/README.md b/README.md index 1209be9..fc3407a 100644 --- a/README.md +++ b/README.md @@ -1,1736 +1 @@ -## NOTICE - -This repository contains the public FTC SDK for the DECODE (2025-2026) competition season. - -## Welcome! -This GitHub repository contains the source code that is used to build an Android app to control a *FIRST* Tech Challenge competition robot.

Gradle and the AGP are now updated to 9.1 and 8.13.2 respectively. - -## Version 11.2 (20260707-102819) - -### Breaking Changes -* Gradle is upgraded to v9.1 and the Android Gradle Plugin is updated to v8.13.2. AGP v8.13.2 requires Android Studio Narwhal 3 Feature Drop or later. Earlier versions of Android Studio will fail to sync the project. Older versions of Android Studio may prompt the user to downgrade AGP. Do not do this. Gradle v9.1 removed support for features that older versions of the AGP use. Updating Gradle fixes a Windows 11 problem some teams may encounter if they have agressive security software installed on their machine. For more context see [this Gradle issue](https://github.com/gradle/gradle/issues/31438) - -### Enhancements -* New type of OpMode is now available. (`@Utility`) - * Utility opmodes that are not disabled will show up in the Utility menu (requires 11.2 or later DS and RC) -* TestHardware Utility now available - * It allows you to test all servos, CR servos, motors, Color sensors, distance sensors, touch sensors, IMUs, webcams, and analog sensors in the config -* TestGamepad Utility now available - * It allows you to see the results of your two gamepads to make sure it is what you expect and find problems with your gamepads. -* Adds methods to PwmControl interface to allow you to setPulseWidth and getPulseWidth - * Both of these are in microseconds (uSeconds) - * This is an ADVANCED feature. There is not a supporting sample. - * NOTE: You may see a slight difference since the hardware is not accurate to the microsecond -* Adds ability to set UVC camera "quirks" from user code to control compatibility flags used inside the low level UVC driver. Addresses issue [1428](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1428) -* Changes Apriltag Axis Display order on camera preview screen, to reflect updated Z axis direction. -* The Driver Station app init button has a light teal background with the word init if - * the driver station and robot controller are connected and have the same team number - * there is at least one gamepad attached - * the timer is enabled (for an Autonomous OpMode) - -### Bug Fixes -* Fixes issue [1949](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1949) overwriting the group with the default group when registering a OpMode with OpModeManager.register(OpModeMeta name, Class clazz) -* Fixes issue mentioned in [1890](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1890) where if - for a servo you change the direction or scaleRange and send the same setPosition that was sent - before, then it wouldn't update the servo. -* Fixes an issue where Self-Inspect doesn't flag a driver station using -RC in it's name. The message is now: - * The team numbers in the robot controller and driver station names do not match, or a device name is invalid. Refer to the FTC Competition Manual for device naming rules. - -## Version 11.1 (20251231-104637) - -### Enhancements - -* Gamepad triggers can now be accessed as booleans and have edge detection supported. -* GoBildaPinpointDriver now supports Pinpoint v2 functionality -* Adds webcam calibrations for goBILDA's USB camera. - -### Bug Fixes -* Fixes issue [1654](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1654) in GoBildaPinpointDriver that caused error if resolution was set in other than MM -* Fixes issue [1628](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1628) Blocks editor displays incorrect Java code for gamepad edge detection blocks. -* Fixes possible race condition issue [1884](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1884) on Driver Station startup when Driver Station name doesn't match the Robot Controller name. -* Fixes issue [1863](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1863) - Incorrect package paths in samples. -* Fixes an issue where an OnBotJava filename that begins with a lowercase character would fail to properly rename the file if the user tried to rename it so that it begins with an uppercase character. - -## Version 11.0 (20250827-105138) - -### Enhancements - -* OnBotJava now has the concept of a project. - A project is a collection of related files. A project may be chosen by selecting 'Example Project' - from the 'File type:' dropdown. Doing so will populate the dropdown to the immediate right with - a list of projects to choose from. - When selecting a project all of the related files appear in the left pane of the workspace - underneath a directory with the chosen project name. - This is useful for example for ConceptExternalHardwareClass which has a dependency upon - RobotHardware. This feature simplifies the usage of this Concept example by automatically - pulling in dependent classes. -* Adds support for AndyMark ToF, IMU, and Color sensors. -* The Driver Station app indicates if WiFi is disabled on the device. -* Adds several features to the Color Processing software: - * DECODE colors `ARTIFACT_GREEN` and `ARTIFACT_PURPLE` - * Choice of the order of pre-processing steps Erode and Dilate - * Best-fit preview shape called `circleFit`, an alternate to the existing `boxFit` - * Sample OpMode `ConceptVisionColorLocator_Circle`, an alternate to the renamed `ConceptVisionColorLocator_Rectangle` -* The Driver Station app play button has a green background with a white play symbol if - * the driver station and robot controller are connected and have the same team number - * there is at least one gamepad attached - * the timer is enabled (for an Autonomous OpMode) -* Updated AprilTag Library for DECODE. Notably, getCurrentGameTagLibrary() now returns DECODE tags. - * Since the AprilTags on the Obelisk should not be used for localization, the ConceptAprilTagLocalization samples only use those tags without the name 'Obelisk' in them. -* OctoQuad I2C driver updated to support firmware v3.x - * Adds support for odometry localizer on MK2 hardware revision - * Adds ability to track position for an absolute encoder across multiple rotations - * Note that some driver APIs have changed; minor updates to user software may be required - * Requires firmware v3.x. For instructions on updating firmware, see - https://github.com/DigitalChickenLabs/OctoQuad/blob/master/documentation/OctoQuadDatasheet_Rev_3.0C.pdf - - -## Version 10.3 (20250625-090416) - -### Breaking Changes -* The behavior of setGlobalErrorMsg() is changed. Note that this is an SDK internal method that is not - meant to be used by team software or third party libraries. Teams or libraries using this method should - find another means to communicate failure. The design intent of setGlobalErrorMsg() is to report an - error and force the user to restart the robot, which in certain circumstances when used inappropriately - could cause a robot to continue running while Driver Station controls are disabled. To prevent this, - processing of a call to setGlobalErrorMsg() is deferred until the robot is in a known safe state. This may - mean that a call to setGlobalErrorMsg() that does not also result in stopping a running OpMode will appear - as though nothing happened until the robot is stopped, at which point, if clearGlobalErrorMsg() has not - been called the message will appear on the Driver Station and a restart will be required. - Addresses issue [1381](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1381) -* Fixes getLatestResult in Limelight3A so if the Limelight hasn't provided data yet, it still returns an LLResult but valid will be false - * If you previously used to check and see if this was `null` to see if the Limelight had been contacted, you now need to use `isValid()` on the result. That is because now it always returns an LLResult even before it talks to the Limelight, but if it doesn't have valid data, the `isValid()` will be `false`. -* Changed all omni samples to use front_left_drive, front_right_drive, back_left_drive, back_right_drive - * This is only breaking for you if you copy one of the changed samples to your own project and expect to use the same robot configuration as before. - -### Known Issues -* The redesigned OnBotJava new file workflow allows the user to use a lowercase letter as the first character of a filename. - This is a regression from 10.2 which required the first character to be uppercase. Software will build, but if the user tries - to rename the file, the rename will fail. - -### Enhancements -* Adds a configuration item for a Full Range Servo. Selecting this item expands the pulse width range from 500us to 2500us. For comparison, the legacy Servo type defines the pulse width range as 600us to 2400us. -* Improved the OBJ new file creation flow workflow. The new flow allows you to easily use samples, craft new custom OpModes and make new Java classes. -* Added support for gamepad edge detection. - * A new sample program `ConceptGamepadEdgeDetection` demonstrates its use. -* Adds a blackboard member to the Opmode that maintains state between opmodes (but not between robot resets). See the ConceptBlackboard sample for how to use it. -* Updated PredominantColorProcessor to also return the predominant color in RGB, HSV and YCrCb color spaces. Updated ConceptVisionColorSensor sample OpMode to display the getAnalysis() result in all three color spaces. -* Adds support for the GoBilda Pinpoint - * Also adds `SensorGoBildaPinpoint` sample to show how to use it -* Added `getArcLength()` and `getCircularity()` to ColorBlobLocatorProcessor.Blob. Added BY_ARC_LENGTH and BY_CIRCULARITY as additional BlobCriteria. -* Added `filterByCriteria()` and `sortByCriteria()` to ColorBlobLocatorProcessor.Util. - * The filter and sort methods for specific criteria have been deprecated. - * The updated sample program `ConceptVisionColorLocator` provides more details on the new syntax. -* Add Help menu item and Help page that is available when connected to the robot controller via Program and Manage. The Help page has links to team resources such as [FTC Documentation](https://ftc-docs.firstinspires.org/), [FTC Discussion Forums](https://ftc-community.firstinspires.org), [Java FTC SDK API Documentation](https://javadoc.io/doc/org.firstinspires.ftc), and [FTC Game Information](https://ftc.game/). -* Self inspection changes: - * List both the Driver Station Name and Robot Controller Name when inspecting the Driver Station. - * Report if the team number portion of the device names do not match. - * -rc is no longer valid as part of a Robot Controller name, must be -RC. - * Use Robot Controller Name or Driver Station Name labels on the inspection screens instead of WIFI Access Point or WIFI Direct Name. - -### Bug Fixes -* Fixes issue [1478](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1478) in AnnotatedHooksClassFilter that ignored exceptions if they occur in one of the SDK app hooks. -* Fix initialize in distance sensor (Rev 2m) to prevent bad data in first call to getDistance. -* Fixes issue [1470](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1470) Scaling a servo range is now irrespective of reverse() being called. For example, if you set the scale range to [0.0, 0.5] and the servo is reversed, it will be from 0.5 to 0.0, NOT 1.0 to 0.5. -* Fixes issue [1232](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1232), a rare race condition where using the log rapidly along with other telemetry could cause a crash. - -## Version 10.2 (20250121-174034) - -### Enhancements -* Add ability to upload the pipeline for Limelight3A which allows teams to version control their limelight pipelines. - - -### Bug Fixes - -* Fix an internal bug where if the RUN_TO_POSITION run mode was specified before a target position, recovery would require a power cycle. A side effect of this fix is that a stack trace identifying the location of the error is always produced in the log. Fixes issue [1345](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1345). -* Throws a helpful exception if region of interest is set to null when building a PredominantColorProcessor. Also sets the default RoI to the full frame. Addresses issue [1076](FIRST-Tech-Challenge/FtcRobotController#1076) -* Throws a helpful exception if user tries to construct an ImageRegion with malformed boundaries. Addresses issue [1078](FIRST-Tech-Challenge/FtcRobotController#1078) - -## Version 10.1.1 (20241102-092223) - -### Breaking Changes - -* Support for Android Studio Ladybug. Requires Android Studio Ladybug. - -### Known Issues - -* Android Studio Ladybug's bundled JDK is version 21. JDK 21 has deprecated support for Java 1.8, and Ladybug will warn on this deprecation. - OnBotJava only supports Java 1.8, therefore, in order to ensure that software developed using Android Studio will - run within the OnBotJava environment, the targetCompatibility and sourceCompatibility versions for the SDK have been left at VERSION_1_8. - FIRST has decided that until it can devote the resources to migrating OnBotJava to a newer version of Java, the deprecation is the - lesser of two non-optimal situations. - -### Enhancements - -* Added `toString()` method to Pose2D -* Added `toString()` method to SparkFunOTOS.Pose2D - -## Version 10.1 (20240919-122750) - -### Enhancements -* Adds new OpenCV-based `VisionProcessor`s (which may be attached to a VisionPortal in either Java or Blocks) to help teams implement color processing via computer vision in the INTO THE DEEP game - * `ColorBlobLocatorProcessor` implements OpenCV color "blob" detection. A new sample program `ConceptVisionColorLocator` demonstrates its use. - * A choice is offered between pre-defined color ranges, or creating a custom one in RGB, HSV, or YCrCb color space - * The ability is provided to restrict detection to a specified Region of Interest on the screen - * Functions for applying erosion / dilation morphing to the threshold mask are provided - * Functions for sorting and filtering the returned data are provided - * `PredominantColorProcessor` allows using a region of the camera as a "long range color sensor" to determine the predominant color of that region. A new sample program `ConceptVisionColorSensor` demonstrates its use. - * The determined predominant color is selected from a discrete set of color "swatches", similar to the MINDSTORMS NXT color sensor - * Documentation on this Color Processing feature can be found here: https://ftc-docs.firstinspires.org/color-processing -* Added Blocks sample programs for color sensors: RobotAutoDriveToLine and SensorColor. -* Updated Self-Inspect to identify mismatched RC/DS software versions as a "caution" rather than a "failure." - -### Bug Fixes -* Fixes [AngularVelocity conversion regression](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/1070) - -## Version 10.0 (20240828-111152) - -### Breaking Changes -* Java classes and Blocks for TensorFlow Object Detection have been removed. -* `AngularVelocity.unit` which was of type `AngleUnit` has been renamed `AngularVelocity.angleUnit` of type `UnnormalizedAngleUnit` - -### Enhancements -* Sample for REV Digital Indicator has been added - ConceptRevLED -* Adds support for the [Sparkfun QWIIC LED Stick](https://www.sparkfun.com/products/18354) - * To connect it directly, you need this [cable](https://www.sparkfun.com/products/25596) -* Adds ConceptLEDStick OpMode -* Adds Blocks for colors black, blue, cyan, dkgray, gray, green, ltgray, magenta, red, white, and yellow. -* Adds an "evaluate but ignore result" Block that executes the connected block and ignores the result. Allows you to call a function and ignore the return value. -* Adds I2C driver for Maxbotix Maxsonar I2CXL sonar rangefinder -* Adds Blocks for setPwmEnable, setPwmDisable, and isPwmEnabled for servos and CR servos. -* In the Blocks editor: a \n in the ExportToBlocks annotation's comment field is displayed as a line break. -* Telemetry has new method setNumDecimalPlaces -* Telemetry now formats doubles and floats (not inside objects, just by themselves) -* Adds support for the Limelight 3A. -* Adds initial support for the REV Servo Hub - * Both the Robot Controller and Driver Station need to be updated to version 10.0 in order for Servo Hubs to be - configurable as Servo Hubs. If the app on either device is outdated, the Servo Hub will show up as an Expansion Hub, - and some functionality will not work as expected. You should wait to create a configuration that includes a Servo Hub - until both the Driver Station and Robot Controller apps have been updated to version 10.0. - * Updating the Servo Hub's firmware and changing its address can only be done using the REV Hardware Client at this time -* Adds support for the REV 9-Axis IMU (REV-31-3332) - * The REV 9-Axis IMU is only supported by the [Universal IMU interface](https://ftc-docs.firstinspires.org/en/latest/programming_resources/imu/imu.html) - * Adds `Rev9AxisImuOrientationOnRobot` Java class. - * If you mentally substitute this IMU's I2C port for the Control Hub's USB ports, `RevHubOrientationOnRobot` is also compatible with this sensor - * Adds Blocks for Rev9AxisImuOrientationOnRobot, including RevHubImuOrientationOnRobot.xyzOrientation and RevHubImuOrientationOnRobot.zyxOrientation. - * Adds Blocks samples SensorRev9AxisIMUOrthogonal and SensorRev9AxisIMUNonOrthogonal. -* Improves Blocks support for RevHubImuOrientationOnRobot. - * Adds Blocks for RevHubImuOrientationOnRobot.xyzOrientation and RevHubImuOrientationOnRobot.zyxOrientation. - * Adds Blocks samples SensorHubIMUOrthogonal (replaces SensorIMU) and SensorHubIMUNonOrthogonal. -* Updates EasyOpenCV, AprilTag, OpenCV, and `libjpeg-turbo` versions -* Adds Blocks for max and min that take two numbers. -* Adds Blocks OpModes ConceptRevSPARKMini, RobotAutoDriveByEncoder, RobotAutoDriveByGyro, RobotAutoDriveByTime, RobotAutoDriveToAprilTagOmni, and RobotAutoDriveToAprilTagTank. -* Two OpModes with the same name now automatically get renamed with the name followed by a "-" and the class name allowing them to both be on the device. -* Shows the name of the active configuration on the Manage page of the Robot Controller Console -* Updated AprilTag Library for INTO THE DEEP. Notably, `getCurrentGameTagLibrary()` now returns INTO THE DEEP tags. -* Adds Blocks for Telemetry.setMsTransmissionInterval and Telemetry.getMsTransmissionInterval. -* Adds Blocks sample SensorOctoQuad. - -### Bug Fixes -* Fixes a bug where the RevBlinkinLedDriver Blocks were under Actuators in the Blocks editor toolbox. They are now Other Devices. -* Fixes a bug where `Exception`s thrown in user code after a stop was requested by the Driver Station would be silently eaten -* Fixed a bug where if you asked for `AngularVelocity` in a unit different than the device reported it in, it would normalize it between -PI and PI for radians, and -180 and 180 for degrees. - -## Version 9.2 (20240701-085519) - -### Important Notes -* Java classes and Blocks for TensorFlow Object Detection have been deprecated and will be removed in Version 10.0. -* The samples that use TensorFlow Object Detection have been removed. - -### Enhancements -* Adds explanatory text to failed items on the inspection activities. To view the explanatory text tap the red warning icon for a failed item. -* In the Blocks editor: added a new kind of variable set block that sets the variable and also returns the new value. -* Changes the way that camera controls behave for a SwitchableCamera.

Attempts to do so will be ignored and logged. - * When an OpMode attempts to illegally manipulate an actuator, the Robot Controller will print a log message - including the text `CANCELLED_FOR_SAFETY`. - * Additionally, LinearOpModes are no longer able to regain the ability to manipulate actuators by removing their - thread's interrupt or using another thread. -* Removes support for Android version 6.0 (Marshmallow). The minSdkVersion is now 24. -* Increases the Robocol version. - * This means an 8.2 or later Robot Controller or Driver Station will not be able to communicate with an 8.1 or earlier Driver Station or Robot Controller. - * If you forget to update both apps at the same time, an error message will be shown explaining which app is older and should be updated. -* FTC_FieldCoordinateSystemDefinition.pdf has been moved. It is still in the git history, but has been removed from the git snapshot corresponding with the 8.2 tag. The official version now lives at [Field Coordinate System](https://ftc-docs.firstinspires.org/field-coordinate-system). -* `LynxUsbDevice.addConfiguredModule()` and `LynxUsbDevice.getConfiguredModule()` have been replaced with `LynxUsbDevice.getOrAddModule()`. -* Old Blocks for Vuforia and TensorFlow Object Detection are obsolete and have been removed from the - Blocks editor's toolbox. Existing Blocks OpModes that contain the old Blocks for Vuforia or - TensorFlow Object Detection can be opened in the Blocks editor, but running them will not work. - -### New features -* Adds new `VisionPortal` API for computer vision - * **This API may be subject to change for final kickoff release!** - * Several new samples added. - * Adds support for detecting AprilTags. - * `VisionPortal` is the new entry point for both AprilTag and TFOD processing. - * Vuforia will be removed in a future release. - * Updated TensorFlow dependencies. - * Added support for webcam camera controls to blocks. - * The Blocks editor's toolbox now has a Vision category, directly above the Utilities category. -* Related documentation for associated technologies can be found at - * [AprilTag Introduction](https://ftc-docs.firstinspires.org/apriltag-intro) - * [AprilTag SDK Guide](https://ftc-docs.firstinspires.org/apriltag-sdk) - * [AprilTag Detection Values](https://ftc-docs.firstinspires.org/apriltag-detection-values) - * [AprilTag Test Images](https://ftc-docs.firstinspires.org/apriltag-test-images) - * [Camera Calibration](https://ftc-docs.firstinspires.org/camera-calibration) -* Adds Driver Station support for Logitech Dual Action and Sony PS5 DualSense gamepads. - * This **does not** include support for the Sony PS5 DualSense Edge gamepad. - * Always refer to Game Manual 1 to determine gamepad legality in competition. -* Adds support for MJPEG payload streaming to UVC driver (external JPEG decompression routine required for use). -* Shows a hint on the Driver Station UI about how to bind a gamepad when buttons are pressed or the sticks are moved on an unbound gamepad. -* Adds option for fullscreening "Camera Stream" on Driver Station. -* OnBotJava source code is automatically saved as a ZIP file on every build with a rolling window of the last 30 builds kept; allows recovering source code from previous builds if code is accidentally deleted or corrupted. -* Adds support for changing the addresses of Expansion Hubs that are not connected directly via USB. - * The Expansion Hub Address Change screen now has an Apply button that changes the addresses without leaving the screen. - * Addresses that are assigned to other hubs connected to the same USB connection or Control Hub are no longer able to be selected. -* Increases maximum size of Blocks inline comments to 100 characters -* Saves position of open Blocks comment balloons -* Adds new AprilTag Driving samples: RobotDriveToAprilTagTank & RobotDriveToAprilTagOmni -* Adds Sample to illustrate optimizing camera exposure for AprilTags: ConceptAprilTagOptimizeExposure - -### Bug Fixes -* Corrects inspection screen to report app version using the SDK version defined in the libraries instead of the version specified in `AndroidManifest.xml`. This corrects the case where the app could show matching versions numbers to the user but still state that the versions did not match. - * If the version specified in `AndroidManifest.xml` does not match the SDK version, an SDK version entry will be displayed on the Manage webpage. -* Fixes no error being displayed when saving a configuration file with duplicate names from the Driver Station. -* Fixes a deadlock in the UVC driver which manifested in https://github.com/OpenFTC/EasyOpenCV/issues/57. -* Fixes a deadlock in the UVC driver that could occur when hot-plugging cameras. -* Fixes UVC driver compatibility with Arducam OV9281 global shutter camera. -* Fixes Emergency Stop condition when an OnBotJava build with duplicate OpMode names occurs. -* Fixes known causes of "Attempted use of a closed LynxModule instance" logspam. -* Fixes the visual identification LED pattern when configuring Expansion Hubs connected via RS-485. - -## Version 8.1.1 (20221201-150726) - -This is a bug fix only release to address the following four issues. - -* [Issue #492](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/492) - Can't create new blocks opmodes. -* [Issue #495](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/495) - Remove the final modifier from the OpMode's Telemetry object. -* [Issue #500](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/500) - Some devices cannot be configured when the Driver Station app has been updated to 8.1 - * Updating either the Robot Controller app or the Driver Station app to 8.1.1 or later will fix this issue. -* The Modern Robotics touch sensor was configurable as a Digital Device. It can only be used as an Analog Device. - -## Version 8.1 (20221121-115119) - -### Breaking Changes -* Deprecates the `OpMode` fields `msStuckDetectInit`, `msStuckDetectInitLoop`, `msStuckDetectStart`, `msStuckDetectLoop`, and `msStuckDetectStop`. - * OpModes no longer have a time limit for `init()`, `init_loop()`, `start()` or `loop()`, so the fields corresponding to those methods are no longer used. - * `stop()` still has a time limit, but it is now hardcoded to be 1 second, and cannot be changed using `msStuckDetectStop`. -* Deprecates the `OpMode` methods `internalPreInit()`, `internalPostInitLoop()`, and `internalPostLoop()`. - * Iterative `OpMode`s will continue to call these methods in case they were overridden. - * These methods will not be called at all for `LinearOpMode`s. -* Deprecates (and stops respecting) `DeviceProperties.xmlTagAliases`. - -### Enhancements -* Adds a new `IMU` interface to Blocks and Java that can be used with both the original BNO055 IMU - included in all older Control Hubs and Expansion Hubs, and the new alternative BHI260AP IMU. - * You can determine which type of IMU is in your Control Hub by navigating to the Manage page of the web interface. - * To learn how to use the new `IMU` interface, see https://ftc-docs.firstinspires.org/programming_resources/imu/imu.html. The `SensorIMU` Blocks sample was also updated to use the new `IMU` interface, and the following Java samples were added: - * `SensorIMUOrthogonal` - * Use this sample if your REV Hub is mounted so that it is parallel or perpendicular to the - bottom of your robot. - * `SensorIMUNonOrthogonal` - * Use this sample if your REV Hub is mounted to your robot in any other orientation - * `ConceptExploringIMUOrientations` - * This OpMode is a tool to help you understand how the orthogonal orientations work, and - which one applies to your robot. - * The BHI260AP IMU can only be accessed via the new `IMU` interface. The BNO055 IMU can be - programmed using the new `IMU` interface, or you can continue to program it using the old `BNO055IMU` - interface. If you want to be able to quickly switch to a new Control Hub that may contain the - BHI260AP IMU, you should migrate your code to use the new `IMU` interface. - * Unlike the old `BNO055IMU` interface, which only worked correctly when the REV Hub was mounted flat - on your robot, the `IMU` interface allows you to specify the orientation of the REV Hub on your - robot. It will account for this, and give you your orientation in a Robot Coordinate System, - instead of a special coordinate system for the REV Hub. As a result, your pitch and yaw will be - 0 when your *robot* is level, instead of when the REV Hub is level, which will result in much - more reliable orientation angle values for most mounting orientations. - * Because of the new robot-centric coordinate system, the pitch and roll angles returned by the - `IMU` interface will be different from the ones returned by the `BNO055IMU` interface. When you are - migrating your code, pay careful attention to the documentation. - * If you have calibrated your BNO055, you can provide that calibration data to the new `IMU` - interface by passing a `BNO055IMUNew.Parameters` instance to `IMU.initialize()`. - * The `IMU` interface is also suitable for implementation by third-party vendors for IMUs that - support providing the orientation in the form of a quaternion. -* Iterative `OpMode`s (as opposed to `LinearOpMode`s) now run on a dedicated thread. - * Cycle times should not be as impacted by everything else going on in the system. - * Slow `OpMode`s can no longer increase the amount of time it takes to process network commands, and vice versa. - * The `init()`, `init_loop()`, `start()` and `loop()` methods no longer need to return within a certain time frame. -* BNO055 IMU legacy driver: restores the ability to initialize in one OpMode, and then have another OpMode re-use that - initialization. This allows you to maintain the 0-yaw position between OpModes, if desired. -* Allows customized versions of device drivers in the FTC SDK to use the same XML tag. - * Before, if you wanted to customize a device driver, you had to copy it to a new class _and_ give - it a new XML tag. Giving it a new XML tag meant that to switch which driver was being used, you - had to modify your configuration file. - * Now, to use your custom driver, all you have to do is specify your custom driver's class when - calling `hardwareMap.get()`. To go back to the original driver, specify the original driver - class. If you specify an interface that is implemented by both the original driver and the - custom driver, there is no guarantee about which implementation will be returned. - -### Bug Fixes -* Fixes accessing the "Manage TensorFlow Lite Models" and "Manage Sounds" links and performing - Blocks and OnBotJava OpMode downloads from the REV Hardware Client. -* Fixes issue where an I2C device driver would be auto-initialized using the parameters assigned in - a previous OpMode run. -* Improves Driver Station popup menu placement in the landscape layout. -* Fixes NullPointerException when attempting to get a non-configured BNO055 IMU in a Blocks OpMode on an RC phone. -* Fixes problem with Blocks if a variable is named `orientation`. - -## Version 8.0 (20220907-131644) - -### Breaking Changes -* Increases the Robocol version. - * This means an 8.0 or later Robot Controller or Driver Station will not be able to communicate with a 7.2 or earlier Driver Station or Robot Controller. - * If you forget to update both apps at the same time, an error message will be shown explaining which app is older and should be updated. -* Initializing I2C devices now happens when you retrieve them from the `HardwareMap` for the first time. - * Previously, all I2C devices would be initialized before the OpMode even began executing, - whether you were actually going to use them or not. This could result in reduced performance and - unnecessary warnings. - * With this change, it is very important for Java users to retrieve all needed devices from the - `HardwareMap` **during the Init phase of the OpMode**. Namely, declare a variable for each hardware - device the OpMode will use, and assign a value to each. Do not do this during the Run phase, or your - OpMode may briefly hang while the devices you are retrieving get initialized. - * OpModes that do not use all of the I2C devices specified in the configuration file should take - less time to initialize. OpModes that do use all of the specified I2C devices should take the - same amount of time as previously. -* Fixes [issue #251](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/251) by changing the order in which axis rotation rates are read from the angular velocity vector in the BNO055 IMU driver. -* Deprecates `pitchMode` in `BNO055IMU.Parameters`. - * Setting `pitchMode` to `PitchMode.WINDOWS` would break the coordinate conventions used by the driver. -* Moves `OpModeManagerImpl` to the `com.qualcomm.robotcore.eventloop.opmode` package. - * This breaks third party libraries EasyOpenCV (version 1.5.1 and earlier) and FTC Dashboard (version 0.4.4 and earlier). -* Deletes the deprecated `OpMode` method `resetStartTime()` (use `resetRuntime()` instead). -* Deletes the protected `LinearOpMode.LinearOpModeHelper` class (which was not meant for use by OpModes). -* Removes I2C Device (Synchronous) config type (deprecated since 2018) - -### Enhancements -* Uncaught exceptions in OpModes no longer require a Restart Robot - * A blue screen popping up with a stacktrace is not an SDK error; this replaces the red text in the telemetry area. - * Since the very first SDK release, OpMode crashes have put the robot into "EMERGENCY STOP" state, only showing the first line of the exception, and requiring the user to press "Restart Robot" to continue - * Exceptions during an OpMode now open a popup window with the same color scheme as the log viewer, containing 15 lines of the exception stacktrace to allow easily tracing down the offending line without needing to connect to view logs over ADB or scroll through large amounts of logs in the log viewer. - * The exception text in the popup window is both zoomable and scrollable just like a webpage. - * Pressing the "OK" button in the popup window will return to the main screen of the Driver Station and allow an OpMode to be run again immediately, without the need to perform a "Restart Robot" -* Adds new Java sample to demonstrate using a hardware class to abstract robot actuators, and share them across multiple OpModes. - * Sample OpMode is [ConceptExternalHardwareClass.java](FtcRobotController/src/main/java/org/firstinspires/ftc/robotcontroller/external/samples/ConceptExternalHardwareClass.java) - * Abstracted hardware class is [RobotHardware.java](FtcRobotController/src/main/java/org/firstinspires/ftc/robotcontroller/external/samples/RobotHardware.java) -* Updates RobotAutoDriveByGyro_Linear Java sample to use REV Control/Expansion hub IMU. -* Updates Vuforia samples to reference PowerPlay assets and have correct names and field locations of image targets. -* Updates TensorFlow samples to reference PowerPlay assets. -* Adds opt-in support for Java 8 language features to the OnBotJava editor. - * To opt in, open the OnBotJava Settings, and check `Enable beta Java 8 support`. - * Note that Java 8 code will only compile when the Robot Controller runs Android 7.0 Nougat or later. - * Please report issues [here](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues). -* In OnBotJava, clicking on build errors now correctly jumps to the correct location. -* Improves OnBotJava autocomplete behavior, to provide better completion options in most cases. -* Adds a QR code to the Robot Controller Inspection Report when viewed from the Driver Station for scanning by inspectors at competition. -* Improves I2C performance and reliability in some scenarios. - -## Version 7.2 (20220723-130006) - -### Breaking Changes -* Updates the build tooling. For Android Studio users, this change requires Android Studio Chipmunk 2021.2.1. -* Removes support for devices that are not competition legal, including Modern Robotics Core Control Modules, the Matrix Controller, and HiTechnic/NXT controllers and sensors. Support remains for Modern Robotics I2C sensors. - -### Enhancements -* Increases the height of the 3-dots Landscape menu touch area on the Driver Station, making it much easier to select. -* Adds `terminateOpModeNow()` method to allow OpModes to cleanly self-exit immediately. -* Adds `opModeInInit()` method to `LinearOpMode` to facilitate init-loops. Similar to `opModeIsActive()` but for the init phase. -* Warns user if they have a Logitech F310 gamepad connected that is set to DirectInput mode. -* Allows SPARKmini motor controllers to react more quickly to speed changes. -* Hides the version number of incorrectly installed sister app (i.e. DS installed on RC device or vice-versa) on inspection screen. -* Adds support for allowing the user to edit the comment for the runOpMode block. -* Adds parameterDefaultValues field to @ExportToBlocks. This provides the ability for a java method with an @ExportToBlocks annotation to specify default values for method parameters when it is shown in the block editor. -* Make LinearOpMode blocks more readable. The opmode name is displayed on the runOpMode block, but not on the other LinearOpMode blocks. -* Added support to TensorFlow Object Detection for using a different frame generator, instead of Vuforia. - Using Vuforia to pass the camera frame to TFOD is still supported. -* Removes usage of Renderscript. -* Fixes logspam on app startup of repeated stacktraces relating to `"Failed resolution of: Landroid/net/wifi/p2p/WifiP2pManager$DeviceInfoListener"` -* Allows disabling bluetooth radio from inspection screen -* Improves warning messages when I2C devices are not responding -* Adds support for controlling the RGB LED present on PS4/Etpark gamepads from OpModes -* Removes legacy Pushbot references from OpMode samples. Renames "Pushbot" samples to "Robot". Motor directions reversed to be compatible with "direct Drive" drive train. - - -### Bug fixes -* Fixes [issue #316](https://github.com/FIRST-Tech-Challenge/FtcRobotController/issues/316) (MatrixF.inverted() returned an incorrectly-sized matrix for 1x1 and 2x2 matrixes). -* Self inspect now allows for Driver Station and Robot Controller compatibility between point releases. -* Fixes bug where if the same `RumbleEffect` object instance was queued for multiple gamepads, it - could happen that both rumble commands would be sent to just one gamepad. -* Fixes bug in Driver Station where on the Driver Hub, if Advanced Gamepad Features was disabled and - an officially supported gamepad was connected, then opening the Advanced Gamepad Features or - Gamepad Type Overrides screens would cause the gamepad to be rebound by the custom USB driver even - though advanced gamepad features was disabled. -* Protects against (unlikely) null pointer exception in Vuforia Localizer. -* Harden OnBotJava and Blocks saves to protect against save issues when disconnecting from Program and Manage -* Fixes issue where the RC app would hang if a REV Hub I2C write failed because the previous I2C - operation was still in progress.

It's worth reviewing those release notes below also. -* Version 5.5 and greater will not work on older Android 4.x and 5.x phones. Users must upgrade to an approved Android 6.x device or newer. -* The default PIDF values for REV motors have been reverted to the default PID values that were used in the 2018-2019 season - * This change was made because the 2018-2019 values turned out to work better for many mechanisms - * This brings the behavior of the REV motors in line with the behavior of all other motors - * If you prefer the 2019-2020 season's behavior for REV motors, here are the PIDF values that were in place, so that you can manually set them in your OpModes: -
- **HD Hex motors (all gearboxes):** - Velocity PIDF values: `P = 1.17`, `I = 0.117`, `F = 11.7` - Position PIDF values: `P = 5.0` - **Core Hex motor:** - Velocity PIDF values: `P = 4.96`, `I = 0.496`, `F = 49.6` - Position PIDF values: `P = 5.0` - -### New features -* Includes TensorFlow inference model and sample OpModes to detect Ultimate Goal Starter Stacks (four rings vs single ring stack). -* Includes Vuforia Ultimate Goal vision targets and sample OpModes. -* Introduces a digital zoom feature for TensorFlow object detection (to detect objects more accurately at greater distances). -* Adds configuration entry for the REV UltraPlanetary HD Hex motor - -### Enhancements -* Adds setGain() and getGain() methods to the NormalizedColorSensor interface - * By setting the gain of a color sensor, you can adjust for different lighting conditions. - For example, if you detect lower color values than expected, you can increase the gain. - * The gain value is only applied to the argb() and getNormalizedColors() methods, not to the raw color methods. - The getNormalizedColors() method is recommended for ease-of-use and clarity, since argb() has to be converted. - * Updates SensorColor Java sample to demonstrate gain usage -* Merges SensorREVColorDistance Java sample into SensorColor Java sample, which showcases best practices for all color sensors -* Improves retrieving values from the REV Color Sensor V3 - * Updates the normalization calculation of the RGB channels - * Improves the calculation of the alpha channel (can be used as an overall brightness indicator) - * Fixes the default sensor resolution, which caused issues with bright environments - * Adds support for changing the resolution and measuring rate of the Broadcom sensor chip - * Removes IR readings and calculations not meant for the Broadcom sensor chip - -### Bug fixes -* Improves reliability of BNO055IMU IMU initialization to prevent random initialization failures (which manifested as `Problem with 'imu'`). - -## Version 5.5 (20200824-090813) - -Version 5.5 requires Android Studio 4.0 or later. - -### New features -* Adds support for calling custom Java classes from Blocks OpModes (fixes [SkyStone issue #161](https://github.com/FIRST-Tech-Challenge/SkyStone/issues/161)). - * Classes must be in the org.firstinspires.ftc.teamcode package. - * To have easy access to the opMode, hardwareMap, telemetry, gamepad1, and gamepad2, classes can - extends org.firstinspires.ftc.robotcore.external.BlocksOpModeCompanion. - * Methods must be public static and have no more than 21 parameters. - * Methods must be annotated with org.firstinspires.ftc.robotcore.external.ExportToBlocks. - * Parameters declared as OpMode, LinearOpMode, Telemetry, and HardwareMap are supported and the - argument is provided automatically, regardless of the order of the parameters. On the block, - the sockets for those parameters are automatically filled in. - * Parameters declared as char or java.lang.Character will accept any block that returns text - and will only use the first character in the text. - * Parameters declared as boolean or java.lang.Boolean will accept any block that returns boolean. - * Parameters declared as byte, java.lang.Byte, short, java.lang.Short, int, java.lang.Integer, - long, or java.lang.Long, will accept any block that returns a number and will round that - value to the nearest whole number. - * Parameters declared as float, java.lang.Float, double, java.lang.Double will accept any - block that returns a number. -* Adds telemetry API method for setting display format - * Classic - * Monospace - * HTML (certain tags only) -* Adds blocks support for switching cameras. -* Adds Blocks support for TensorFlow Object Detection with a custom model. -* Adds support for uploading a custom TensorFlow Object Detection model in the Manage page, which - is especially useful for Blocks and OnBotJava users. -* Shows new Control Hub blink codes when the Wi-Fi band is switched using the Control Hub's button (only possible on Control Hub OS 1.1.2) -* Adds new warnings which can be disabled in the Advanced RC Settings - * Mismatched app versions warning - * Unnecessary 2.4 GHz Wi-Fi usage warning - * REV Hub is running outdated firmware (older than version 1.8.2) -* Adds support for Sony PS4 gamepad, and reworks how gamepads work on the Driver Station - * Removes preference which sets gamepad type based on driver position. Replaced with menu which allows specifying type for gamepads with unknown VID and PID - * Attempts to auto-detect gamepad type based on USB VID and PID - * If gamepad VID and PID is not known, use type specified by user for that VID and PID - * If gamepad VID and PID is not known AND the user has not specified a type for that VID and PID, an educated guess is made about how to map the gamepad -* Driver Station will now attempt to automatically recover from a gamepad disconnecting, and re-assign it to the position it was assigned to when it dropped - * If only one gamepad is assigned and it drops: it can be recovered - * If two gamepads are assigned, and have **different** VID/PID signatures, and only one drops: it will be recovered - * If two gamepads are assigned, and have **different** VID/PID signatures, and BOTH drop: both will be recovered - * If two gamepads are assigned, and have **the same** VID/PID signatures, and only one drops: it will be recovered - * If two gamepads are assigned, and have **the same** VID/PID signatures, and BOTH drop: **neither** will be recovered, because of the ambiguity of the gamepads when they re-appear on the USB bus. - * There is currently one known edge case: if there are **two** gamepads with **the same** VID/PID signature plugged in, **but only one is assigned**, and they BOTH drop, it's a 50-50 chance of which one will be chosen for automatic recovery to the assigned position: it is determined by whichever one is re-enumerated first by the USB bus controller. -* Adds landscape user interface to Driver Station - * New feature: practice timer with audio cues - * New feature (Control Hub only): wireless network connection strength indicator (0-5 bars) - * New feature (Control Hub only): tapping on the ping/channel display will switch to an alternate display showing radio RX dBm and link speed (tap again to switch back) - * The layout will NOT autorotate.

Bulk data can read through `LynxModule#getBulkData()` and processed manually. - * `BulkCachingMode.AUTO`: Applicable hardware calls are served from a bulk read cache that is cleared/refreshed automatically to ensure identical commands don't hit the same cache. The cache can also be cleared manually with `LynxModule#clearBulkCache()`, although this is not recommended. - * (advanced users) `BulkCachingMode.MANUAL`: Same as `BulkCachingMode.AUTO` except the cache is never cleared automatically. To avoid getting stale data, the cache must be manually cleared at the beginning of each loop body or as the user deems appropriate. -* Removes PIDF Annotation values added in Rev 5.3 (to AndyMark, goBILDA and TETRIX motor configurations). - * The new motor types will still be available but their Default control behavior will revert back to Rev 5.2 -* Adds new `ConceptMotorBulkRead` sample Opmode to demonstrate and compare Motor Bulk-Read modes for reducing I/O latencies. - -## Version 5.3 (20191004-112306) -* Fixes external USB/UVC webcam support -* Makes various bugfixes and improvements to Blocks page, including but not limited to: - * Many visual tweaks - * Browser zoom and window resize behave better - * Resizing the Java preview pane works better and more consistently across browsers - * The Java preview pane consistently gets scrollbars when needed - * The Java preview pane is hidden by default on phones - * Internet Explorer 11 should work - * Large dropdown lists display properly on lower res screens - * Disabled buttons are now visually identifiable as disabled - * A warning is shown if a user selects a TFOD sample, but their device is not compatible - * Warning messages in a Blocks OpMode are now visible by default. -* Adds goBILDA 5201 and 5202 motors to Robot Configurator -* Adds PIDF Annotation values to AndyMark, goBILDA and TETRIX motor configurations. - This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use - PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control. - PIDF adds Feedforward control to the basic PID control loop. - Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage - must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently. - The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor. - The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be. -* Fixes startup crash on Android 10 -* Fixes [ftc_app issue #712](https://github.com/ftctechnh/ftc_app/issues/712) (thanks to FROGbots-4634) -* Fixes [ftc_app issue #542](https://github.com/ftctechnh/ftc_app/issues/542) -* Allows "A" and lowercase letters when naming device through RC and DS apps. - -## Version 5.2 (20190905-083277) -* Fixes extra-wide margins on settings activities, and placement of the new configuration button -* Adds Skystone Vuforia image target data. - * Includes sample Skystone Vuforia Navigation OpModes (Java). - * Includes sample Skystone Vuforia Navigation OpModes (Blocks). -* Adds TensorFlow inference model (.tflite) for Skystone game elements. - * Includes sample Skystone TensorFlow OpModes (Java). - * Includes sample Skystone TensorFlow OpModes (Blocks). -* Removes older (season-specific) sample OpModes. -* Includes 64-bit support (to comply with [Google Play requirements](https://android-developers.googleblog.com/2019/01/get-your-apps-ready-for-64-bit.html)). -* Protects against Stuck OpModes when a Restart Robot is requested.

To hide the stream, select the same menu item again. - * Note that gamepads are disabled and the selected opmode cannot be started while the stream is open as a safety precaution. - * To use custom streams, consult the API docs for `CameraStreamServer#setSource` and `CameraStreamSource`. -* Adds many Star Wars sounds to RobotController resources. -* Added Skystone Sounds Chooser Sample Program. -* Switches out startup, connect chimes, and error/warning sounds for Star Wars sounds -* Updates OnBot Java to use a WebSocket for communication with the robot - * The OnBot Java page no longer has to do a full refresh when a user switches from editing one file to another - -Known issues: -* Camera Stream - * The Vuforia camera stream inherits the issues present in the phone preview (namely [ftc_app issue #574](https://github.com/ftctechnh/ftc_app/issues/574)). This problem does not affect the TFOD camera stream even though it receives frames from Vuforia. - * The orientation of the stream frames may not always match the phone preview. For now, these frames may be rotated manually via a custom `CameraStreamSource` if desired. -* OnBotJava - * Browser back button may not always work correctly - * It's possible for a build to be queued, but not started. The OnBot Java build console will display a warning if this occurs. - * A user might not realize they are editing a different file if the user inadvertently switches from one file to another since this switch is now seamless. The name of the currently open file is displayed in the browser tab. - -## Version 5.0 (built on 19.06.14) - * Support for the REV Robotics Control Hub. - * Adds a Java preview pane to the Blocks editor. - * Adds a new offline export feature to the Blocks editor. - * Display Wi-Fi channel in Network circle on Driver Station. - * Adds calibration for Logitech C270 - * Updates build tooling and target SDK. - * Compliance with Google's permissions infrastructure (Required after build tooling update). - * Keep Alives to mitigate the Motorola Wi-Fi scanning problem.

- If an Expansion Hub accidentally gets "bricked" the Robot Controller app is now more likely to recognize the Hub when it scans the USB bus. - + Robot Controller app should be able to detect an Expansion Hub, even if it accidentally was bricked in a previous update attempt. - + Robot Controller app should be able to install the firmware onto the Hub, even if if accidentally was bricked in a previous update attempt. - - * Resiliency - - FTC software can detect and enable an FTDI reset feature that is available with REV Robotics v1.8 Expansion Hub firmware and greater. - + When enabled, the Expansion Hub can detect if it hasn't communicated with the Robot Controller over the FTDI (USB) connection. - + If the Hub hasn't heard from the Robot Controller in a while, it will reset the FTDI connection. - + This action helps system recover from some ESD-induced disruptions. - - Various fixes to improve reliability of FTC software. - - * Blocks - - Fixed errors with string and list indices in blocks export to java. -

Version 3.00 software uses a new version of the FTC Robocol (robot protocol). If you upgrade to v3.0 on the Robot Controller and/or Android Studio side, you must also upgrade the Driver Station software to match the new Robocol. -2. Version 3.00 software removes the setMaxSpeed and getMaxSpeed methods from the DcMotor class. If you have an OpMode that formerly used these methods, you will need to remove the references/calls to these methods. Instead, v3.0 provides the max speed information through the use of motor profiles that are selected by the user during robot configuration. -3. Version 3.00 software currently does not have a mechanism to disable extra i2c sensors. We hope to re-introduce this function with a release in the near future. - -************************************************************************************** - -## Version 3.00 (built on 17.04.13) - -*** Use this version of the software at YOUR OWN RISK!!! *** - -This software is being released as an "alpha" version.

For example, suppose a servo controller dies on your robot. You replace the broken module with a new module, which has a different serial number from the original servo controller. You can use the Fix button to automatically reconfigure your configuration file to use the serial number of the new module. - * Improvements made to fix resiliency and responsiveness of the system. - * For LinearOpMode the user now must for a telemetry.update() to update the telemetry data on the driver station. This update() mechanism ensures that the driver station gets the updated data properly and at the same time. - * The Auto Configure function of the Robot Controller is now template based. If there is a commonly used robot configuration, a template can be created so that the Auto Configure mechanism can be used to quickly configure a robot of this type. - * The logic to detect a runaway OpMode (both in the LinearOpMode and OpMode types) and to abort the run, then auto recover has been improved/implemented. - * Fix has been incorporated so that Logitech F310 gamepad mappings will be correct for Marshmallow users. - -## Release 16.07.08 - - * For the ftc_app project, the gradle files have been modified to support Android Studio 2.1.x. - -## Release 16.03.30 - - * For the MIT App Inventor, the design blocks have new icons that better represent the function of each design component. - * Some changes were made to the shutdown logic to ensure the robust shutdown of some of our USB services. - * A change was made to LinearOpMode so as to allow a given instance to be executed more than once, which is required for the App Inventor. - * Javadoc improved/updated. - -## Release 16.03.09 - - * Changes made to make the FTC SDK synchronous (significant change!) - - waitOneFullHardwareCycle() and waitForNextHardwareCycle() are no longer needed and have been deprecated. - - runOpMode() (for a LinearOpMode) is now decoupled from the system's hardware read/write thread. - - loop() (for an OpMode) is now decoupled from the system's hardware read/write thread. - - Methods are synchronous. - - For example, if you call setMode(DcMotorController.RunMode.RESET_ENCODERS) for a motor, the encoder is guaranteed to be reset when the method call is complete. - - For legacy module (NXT compatible), user no longer has to toggle between read and write modes when reading from or writing to a legacy device. - * Changes made to enhance reliability/robustness during ESD event. - * Changes made to make code thread safe. - * Debug keystore added so that user-generated robot controller APKs will all use the same signed key (to avoid conflicts if a team has multiple developer laptops for example). - * Firmware version information for Modern Robotics modules are now logged. - * Changes made to improve USB comm reliability and robustness. - * Added support for voltage indicator for legacy (NXT-compatible) motor controllers. - * Changes made to provide auto stop capabilities for OpModes. - - A LinearOpMode class will stop when the statements in runOpMode() are complete. User does not have to push the stop button on the driver station. - - If an OpMode is stopped by the driver station, but there is a run away/uninterruptible thread persisting, the app will log an error message then force itself to crash to stop the runaway thread. - * Driver Station UI modified to display lowest measured voltage below current voltage (12V battery). - * Driver Station UI modified to have color background for current voltage (green=good, yellow=caution, red=danger, extremely low voltage). - * javadoc improved (edits and additional classes). - * Added app build time to About activity for driver station and robot controller apps. - * Display local IP addresses on Driver Station About activity. - * Added I2cDeviceSynchImpl. - * Added I2cDeviceSync interface. - * Added seconds() and milliseconds() to ElapsedTime for clarity. - * Added getCallbackCount() to I2cDevice. - * Added missing clearI2cPortActionFlag. - * Added code to create log messages while waiting for LinearOpMode shutdown. - * Fix so Wi-Fi Direct Config activity will no longer launch multiple times. - * Added the ability to specify an alternate i2c address in software for the Modern Robotics gyro. - -## Release 16.02.09 - - * Improved battery checker feature so that voltage values get refreshed regularly (every 250 msec) on Driver Station (DS) user interface. - * Improved software so that Robot Controller (RC) is much more resilient and “self-healing” to USB disconnects: - - If user attempts to start/restart RC with one or more module missing, it will display a warning but still start up. - - When running an OpMode, if one or more modules gets disconnected, the RC & DS will display warnings,and robot will keep on working in spite of the missing module(s). - - If a disconnected module gets physically reconnected the RC will auto detect the module and the user will regain control of the recently connected module. - - Warning messages are more helpful (identifies the type of module that’s missing plus its USB serial number). - * Code changes to fix the null gamepad reference when users try to reference the gamepads in the init() portion of their OpMode. - * NXT light sensor output is now properly scaled. Note that teams might have to readjust their light threshold values in their OpModes. - * On DS user interface, gamepad icon for a driver will disappear if the matching gamepad is disconnected or if that gamepad gets designated as a different driver. - * Robot Protocol (ROBOCOL) version number info is displayed in About screen on RC and DS apps. - * Incorporated a display filter on pairing screen to filter out devices that don’t use the “-“ format. This filter can be turned off to show all Wi-Fi Direct devices. - * Updated text in License file. - * Fixed formatting error in OpticalDistanceSensor.toString(). - * Fixed issue on with a blank (“”) device name that would disrupt Wi-Fi Direct Pairing. - * Made a change so that the Wi-Fi info and battery info can be displayed more quickly on the DS upon connecting to RC. - * Improved javadoc generation. - * Modified code to make it easier to support language localization in the future. -
