MMC5xx3 Compass not supported?

ArduCopter Copter 4.0

Hi,
i wanted to test a new compass and saw that in the Compass Library this is included


However i cant get the compass to work.
At a closer look it doesn’t seem that it is referenced anywhere else in the code.

Is this on purpose that it is not integrated and only the library is present ?
Thanks,
Daniel

So we got it to work, but now the auto rotation while calibrating has the compass 180° offset
Is this maybe caused because the chip uses a right Hand corrdinate System ?
I coudnt find so far how this is handled with other Sensors, most of them seem to be left hand
