Tilt compensation compass (mpu9250/6500)
#1
As I am (trying) to move away from the Moitessier, I am stumped by the behavior of my MPU. 

It's a MPU 9250/6400 that I connected to the GPIO pins. When level I get proper readings.

I know tilt-compensation is a thing, but I naively assumed this was handled by PyPilot.
Sadly, this is very much not the case: At 30 degrees tilt (heel) the compass is off by more than 45 degrees. 
Both the accelerometers and the compass have been calibrated using PyPilot. 
Needless to say my Moitessier does not have this problem.

If this is a hardware thing, please advice me which MPU I should buy (including a link if at all possible) as specs are not always as clear as I'd like..

Thank you for your hints!
