Detailed Description

This is part of Adafruit's FXAS21002C driver for the Arduino platform. It is designed specifically to work with the Adafruit FXAS21002C breakout: https://www.adafruit.com/products/3463

These sensors use I2C to communicate, 2 pins (SCL+SDA) are required to interface with the breakout.
