Now that my telemetry is working on the new code I was able to connect to my copter by mission planner, however the AH works OK initially, when I tilt the copter the AH reflects the correct display.
Then a few seconds later the AH goes crazy, pitch, roll, inverted, spinning and the compass shows all different headings.
I have the DIYDrones magnometer mounted pins forward components down.
I'm not sure if its because of how I'm connecting it to the APM.
I didn't want to solder the device onto the APM I've got it connected to the I2C port.
I soldered this onto the magnometer board
and I attach that via this cable to the I2C port
That's the only thing I'm doing that's undocumented, so can anyone tell me if the way I've done it is not going to work (before I start unsoldering)
