Ivan Rush / Mbed 2 deprecated MMA8452_Demo

The main.cpp program below demonstrates a simple way to interface with the MMA8452 accelerometer. The function reads in the acceleration data in the X, Y, and Z directions and displays them through a serial com port on a PC. The Putty Output figure below shows the output of the accelerometer using Putty. The program also dims or brightens the mbed LEDs 1-3 based on whether or not they are at 'level'( 0 Gs) or above respectively. The video below previews the code in action.

Dependencies:   MMA8452 mbed
