Implementation of eCompass

Question asked by Vitaliy Siplichuk on May 27, 2015

I want to implement eCompass in my device. I have ma3110 and FXLC95000 for that.

There are App notes for that AN4248.pdf and AN4246.pdf. But there is source code only for hard iron correction.
1. Can anyone give me the source code for both hard and soft-iron correction to use with code from AN4248.pdf and AN4246.pdf?
2. And the second question. As I know we need to calibrate our sensors if we use one magnetometer. But I want to use two magnetometers to make computation without calibration. As I know it is possible. Am I right? If yes, what changes should I do in my computation?
