Tisham Dhar / Mbed 2 deprecated Xadow_MPU9150AHRS

This program is designed to run on a set of Xadow M0 modules to create a Hotshoe IMU which outputs GPS and Orientation data to Nikon cameras, as well as triggering the camera at set intervals.

Dependencies:   MBed_Adafruit-GPS-Library SC16IS750 SDFileSystem SSD1308_128x64_I2C USBDevice mbed BMP085
