Gyro Calibration
 
AQRS-00075 is the gyro i am trying to calibrate via Kevin's code. I can get the gyro to 1800 when it is at 180 degrees but for some reason it never ever goes back to 0 when i return it to its original position. I am moving it pretty slowly so i do not think it ever gets saturated. I was wondering if people ran into similar problems and whether it was a hardware problem (the gyro is broken) or technicial issue (the gyro we have just doesn't cut it)

Thanks for any input

What scaling factor did you end up with after calibration? How much drift are you seeing (degrees per minute)? How far from zero is it when you rotate it back? Did you follow *all* of the instructions contained in readme.txt and gyro.h?
