Just wondering if anyone has any experience debugging I2C issues. I had a plane that I maidened without any telemetry radio or FPV gear, and the compass worked fine.
I added a Holybro 915MHz SiK radio, a Foxeer Toothless 2 FPV cam, and a Rush Tank Ultimate Plus VTX, and now when I power on it shows the compass as “missing” most times. I couldn’t sort it out, so I ended up just disabling the compass for my next flights, but I’d like to get it back.
I had used the full length of the wires that came with the GPS, plus another inch and a bit. Is this an issue with cable length or just electrical interference? Is there any setting I can adjust in ArduPlane to improve things or do I need to start using shielding or something?
