Hello all,I upgraded my APM 2.5 board to enable the external compass and gps. I cut he trace between the two pads, I've upgraded the firmware to 3.1. I'm trying to calibrate the compass and seem to be having problems. The first two values come in ok but the third value is out of tolerance. The first value is typically a - 2 digit number, the second value is a positive 2 digit number and the third value is usually around positive 190 + or - 15.I've tried recalibrating numerous time. I've tried inside and outside the house. Nothing corrects it.Any other ideas?Thanks.
