Added type safety to blocks for Temperature. Added type safety to blocks for TouchSensor. Added type safety to blocks for UltrasonicSensor.

Added type safety to blocks for VectorF. Added type safety to blocks for Velocity. Added type safety to blocks for VoltageSensor. Added type safety to blocks for VuforiaLocalizer.

Added type safety to blocks for VuforiaTrackable. Added type safety to blocks for VuforiaTrackables. Added blocks to support Acceleration. Added blocks to support LinearOpMode. Added blocks to support MagneticFlux and Position. Fixed typos. Made blocks for ElapsedTime more consistent with other objects.

Fixed a few blocks. Added type checking to new blocks. Updated to latest blockly. Added default variable blocks to navigation and matrix blocks. When user downloads Blocks-generated op mode, only the.

When user uploads Blocks-generated op mode. Added DbgLog support. Fixed bug to properly render blocks even if missing devices from configuration file. Added support for additional characters not just alphanumeric for the block file names for download and upload. Changes to Samples to prevent tutorial issues. Remove Servo Glitches when robot stopped.

Added log info to help diagnose why the Robot Controller app was terminated for example, by watch dog function. Added ability to transfer log from the controller. Fixed inconsistency for AngularVelocity Limit unbounded growth of data for telemetry. If user does not call telemetry. Update to Vuforia 6. Fix for autonomous 30 second timer bug where timer was in effect, even though it appeared to have timed out. Fix to avoid reading i2c twice. Updated sample Op Modes.

Improved logging and fixed intermittent freezing. Cleaned up device names in sample op modes to be consistent with Pushbot guide. Fix to allow use of IrSeekerSensorV3. Support for Modern Robotics Range Sensor. Revise device names for Pushbot templates to match the names used in Pushbot guide. Modified computer vision code to require an individual Vuforia license per legal requirement from PTC.

Minor fixes. Blockly enhancements: Support for Voltage Sensor. Support for Analog Input. Support for Analog Output. Support for Light Sensor.

Support for Servo Controller. Updated sample gyro program. Blockly enhancements support for android. Provides ability to disable audio cues. Standardized units in analog input. Cleaned up code for existing analog sensor classes. This is important - we no longer set the motor modes through the motor controller. Some changes have been made new methods added on how a user can access items from the hardware map.

Users can now set the zero power behavior for a DC motor so that the motor will brake or float when power is zero. Users can place the Robot Controller into this mode, and then use a device such as a laptop that has a Javascript enabled browser to write Blockly-based Op Modes directly onto the Robot Controller. Android Studio project supports Android Studio 2.

Users can use sample vision targets to get localization information on a standard FTC field. For example, if you have two motor controllers on a robot, and you misidentified them in your configuration file, you can use the Swap button to swap the devices within the configuration file so you do not have to manually re-enter in the configuration info for the two devices. Fix mechanism added to all user to replace an electronic module easily. 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. 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. Fix has been incorporated so that Logitech F gamepad mappings will be correct for Marshmallow users. Release 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. Methods are synchronous. For example, if you call setMode DcMotorController. 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 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 op modes.

User does not have to push the stop button on the driver station. Driver Station UI modified to display lowest measured voltage below current voltage 12V battery. Added app build time to About activity for driver station and robot controller apps. 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 Wifi 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. 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. Code changes to fix the null gamepad reference when users try to reference the gamepads in the init portion of their op mode.

NXT light sensor output is now properly scaled. Note that teams might have to readjust their light threshold values in their op modes. 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. This filter can be turned off to show all WiFi Direct devices. Updated text in License file. Fixed formatting error in OpticalDistanceSensor. Improved javadoc generation. Modified code to make it easier to support language localization in the future.

Example MRGyroTest. Improved error messages More descriptive error messages for exceptions in user code. USB-related code changes to make USB comm more responsive and to display more explicit error messages. Fix USB initializtion race condition.

Better error reporting during FTDI open. More explicit messages during USB failures. Fixed bug so that USB device is closed if event loop teardown method was not called. Fixed race condition in EventLoopManager. Fix to keep references stable when updating gamepad. Updated comments in LinearI2cAddressChange. Removed K9AutoTime.

Added MRGyroTest. Added MatrixControllerDemo. Updated javadoc documentation.
