Version 3.1_fixed Release
This is the most current official release of the FTC software development kit. Version 3.1_fixed introduces support for the REV Expansion Hub electronic module. This version also includes changes to the USB communication layer to improve system resiliency. This version also has improvements, including simplified Vuforia blocks and additional Vuforia functionality, to the FTC Blocks robot hosted programming tool.
Note version "v3.1_fixed" removes the "SensorAdafruitIMU.java" and SensorAdafruitIMUCalibration.java" sample op modes which prevented the project from building. The SensorAdafruitIMU class has been changed (refactored) to BNO055IMU since the REV Expansion Hub also uses the same Bosch BNO055 IMU chip as the Adafruit device.
If you were previously using a 2.x version of the FTC software, you will need to update the FTC Driver Station app in addition to updating the FTC Robot Controller app and/or the FTC Robot Controller Android Studio project folder.
The version 2.2 documentation is still applicable, but this older version of the documentation does not include specific instructions on how to configure the REV Expansion Hub hardware.
