hi guys...im trying to figure out what the math should be to calibrate one axis to "level".
lets say the error in the measurement is 2 degrees....andi have a surface that is unknown levelness....
if i take a touch beta measurement on that surface, then rotate the phone 180 degrees and take a second measurement, i get the error shouldwork out to be :
error = (measurement1+measurement2)/2
then subract the error from the touchb.beta and you should have the anglular measurement relative to actual level.
but its not working for some reason and im not sure why
