Thank you very much for the information, it had a warning but i wasn't sure.
Btw i don't use a magnetometer with DCM but the GCS still shows the aircraft rotating (while gps is offline) and the Yaw field of the "ATTITUDE" message is updated If i turn the airplane by hand in absolute proportion with the magnetometer output.
Normally it shouldn't do this since "USE_MAGNETOMETER" has a value of zero
<define name="USE_MAGNETOMETER" value="0"/>
<define name="USE_MAGNETOMETER_ONGROUND" value="0"/>
It looks like the values of the magnetometer from inside the IMU driver are used further down in the code despite the "USE_MAGNETOMETER" definition's value
