Overview

Initial code to get quaternion output from DMP. Outputs quaternion values as hexadecimal strings like q: 1d7b8d3f ff686626 ff8e7e00 38ccc5a4. The format for each part is big-endian long which python struct can read as

struct.unpack('>l', "ff686626".split[j].decode('hex'))[0]

Can divide all parts by 1073741824.0(1<<30), or normalize quaternion before use.

The function send_packet is not used, but it sends raw gyro, accel readings fine when configured.

There is a test.py application in desktop/, which draws a cube rotating cube according to quaternion output it recieved from serial port.

Notes

Compiler is gcc version 4.5.2 MPLAB XC32 Compiler v1.20 (Microchip Technology). Have FOOTSENSE_TARGET_PIC32 and MPU9150 in global preprocessor defines.
