accel

This project demonstrates interfacing of Accelerometer and RGB LCD with Dragonboard 410C using libupm and libmraa. LCD will show the XYZ acceleration readings with blue background in ideal mode. If shake is detected, color will change to Red and if tap is detected, color will change to Green.
