Draft
Offset Correction
After read-out of the X and Y value first the temperature corrected offset value has to be
subtracted.
Amplitude Normalization
Then the X and Y values are normalized using the peak values determined in the
calibration.
Non-Orthogonality Correction
The influence of the non-orthogonality can be compensated using following equation.
Only the Y channel has to be corrected.
Resulting Angle
After correction of all errors, the resulting angle can be calculated using the arctan
function
