Motion Plug library
Originally by rpicopter: https://github.com/rpicopter/ArduinoMotionSensorExample
- uses FastWire and I2Cdev from Jeff Rowberg
- DMP enabled
- calculates and displays gyro and quaternions
This has been tested using Arduino 1.0.5, 1.6.1, a few variants of Arduino Pro Mini boards, the Modern Device Robot Board Rev E. (a mega2560), and the JeeNode SMD.
