I'm going mental. Can someone please tell me how to set AHRS Orientation and Compass Orientation for the following setup:
PX4 upside down and front pointing to the left of the vehicle
GPS module upright and front to the front of the vehicle
I thought AHRS orientation should be "14", but I can't work out how to determine the Compass orientation relative to that. I'm getting a compass heading that's about 45 degrees off the actual vehicle heading.
