Hi,

I tried everything, resoldered, but still the channel 2 input not working in my APM 2.5

Is it possible to change the channel 2 with any other free channel like ch7,ch8?

channel 2 is pitch

Really feeling sad, this is my first costly board I bought but after this I feel dead.

Please guide me on how to change the code for this, if you have been through the process.

Thanks,

Rahul

You have done the radio calibration, of course? I presume if you plug a servo into CH2 on your Rx the servo works fine? Likewise if you swop the cables or use another extension you still get no output on pitch in the Mission Planner (With CH2 OUT on Rx plugged into CH2 IN on APM?

Try plug CH1 output from Rx into CH2 IN on the APM, do you see movement of the pitch bar when you move the roll stick? If you still see no movement you may have a defective board.

Explain your setup and how you know CH2 input is not working? Also tell us what you've done exactly to try find the cause? Are you getting CH2 out of your receiver?
