View MMA8452Q.cpp
/*
* Arduino library for the MMA8452Q three-axis accelerometer.
*
* The MMA8452Q is a tiny and low-power three-axis accelerometer. This
* library implements a simple interface to access most of the chip
* functionality from an Arduino.
*
* FEATURES:
* + Normal and fast raw axes values reading
* + Scale configuration (allowed 2g, 4g and 8g scales)
