Hey Guys.

I wanted to replace one of my switches with a pot so I can control my gimbal beter.
I assume this is possible since the devo7 does have a pot ?
I haven't been able to source any spare parts for it sadly

No it is not possible.
All of the switches are connected to digital-only pins, and you can't read an analog signal from them.

If you have good soldering skills, you could potentially solder directly to the MCU to make it work, but it is pretty tricky work, especially working with analog signals. Pin PA0 would be a likely candidate, but you'd need to know what you are doing to make it work.

Alternatively an a/d + shift-register could probably do it on a digital pin, but it would take a lot of coding to make happen. Easier to just attacxh it to the PWM in that case.

And how i can configure, that PA0 is gone to one of the 8 channels of RX802?

This has become my biggest frustration with my 8S as well. I have a trim button set up to control my gimbal but it's rather awkward.

yea it works but a pot would be a way nicer solution

maybe I can control my gimbal with the headtracking from my boscam goggles
wil see if I can get that working\
