APM2 - How to pass a CPPM channel through to another output? - Discussions

Previously, I was using a receiver that had 7 channels running into the APM individually and 1 running to a separate arduino that I use to control custom camera trigger and mode functions (selected via a PWM switch mix).

I just changed to a new receiver and am outputting all channels (1-8) to the APM on 1 signal line with CPPM.

So, everything is great except I am not sure how to pass that 1 channel through to my other arduino now.

Ideas? Basically what I need is the gimbal shutter control functionality that instead uses an input override so that I can just pass my PWM signal to an available output channel on the APM.

If there is a simple way and I am over-thinking this...then great! Thanks.

If there isn't a way, can I request some type of patch-through functionality be added so that you can use CPPM but still output individual channel PWM signals from APM? Or maybe just a revision of the camera shutter feature in the gimbal section so that I can send the PWM signal from a channel switch/knob instead of putting in set values?

I can try to look into the code myself but I'm hoping there is someone here already more familiar that can help me out. Thanks.

I actually need channel 6 separately.

The impedance on the Arduino is very high, so you can simply just connect the CPPM signal line to the other Arduino. It would only react to the signal for CH1. It should be straight forward.
