Hello everybody!

I have bought STM32F3-Discovery. In first step I used sample of ST. When I try read correct HeadingValue I have one problem. I have a feeling that this value is shifted. Some W,S (west, south) react as well but I didn't pleased.

Do you have such a problem? Do you know what I mean?

No.

Do you know what I mean?

Maybe.

The heading value of the demo software mostly depends on the measurements of the magnetic field sensor. To get useful measurements, you need to provide an environment with minimal EM interference. And for more accurate output, you will need to calibrate the module.
