/**
* {@link SensorBNO055IMU} gives a short demo on how to use the BNO055 Inertial Motion Unit (IMU) from AdaFruit.
*
* Note: this is a Legacy example that will not work with newer Control/Expansion Hubs that use a different IMU
* Please use the new SensorIMUOrthogonal or SensorIMUNonOrthogonal samples for a more universal IMU interface.
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this opmode to the Driver Station OpMode list
