BMM150 Bosch geomagnetic sensor Z axis problem

[stefan.erni]

Hi Ben

Can you have a look if at the component BMM150 if is a problem reading Z axis?
It could be that at the Z axis MSB and LSB are swapped or not correct.
Somehow for this component, the register for z axis are not built same way as for x axis and y axis
If I read the registers directly I get reasonable values.

Stefan

Hi Ben

I am not sure, the X and Y axis are also not in correct.
When I read the registers directly I get different values. I have tested these new values
I used a magnet to test the XYZ axes and the readings seem to be ok.
