Offset Correction
After the X and Y values are read out, the temperature-corrected offset value must be subtracted.
Amplitude Normalization
Next, 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 thefollowing equation, in which only the Y
channel must be corrected.
Resulting Angle
After correction of all errors, the resulting angle can be calculated using the arctan function
1) Microcontroller function “arctan2(Y
