Written in Propeller Assembly uses a 'cordic' routine to convert x and y tilt information into polar coordinates. Output is RAW data, but can easily be resolved into acceleration (ro) and degrees (theta). Upon startup, the demo expects the accelerometer to be in a level position for an initial calibration leveling routine.
