One of my customer is about to make simple compass using MAG3110.
It just need to indicate the magnetic or true north.
1. In this case, should they use the soft/hard iron compensation?
2. If so, is it possible to perform complicated matrix calculation thru PIC16F1936?
3. Do Freescale provide the equation as a source or library form?
4. Do Freescale provide I2C example code?
