Nihui U807 / Flysky V6x6

Hello, I got a brandnew Nihui U807 and it flies well with my Devo 7e. I'm trying to use the camera that came with it but I have trouble to configure some channels. So far I can switch video and headless on and off. Weird thing is these are on channel 9 (video) and 10 (headless) while the description of the V6x6 protocol says it's 8 and 9. Does anybody know how I can use the photo function? I can't even tell which channel it is. Thanks!

I am not sure about this, but I think video function and photo function might be on the same channel just with different values. Try using a three possitions switch and see if you can get it to take photos by applying a different value that the one you use now (say 0 for off, -100 for photos and +100 for video, or the opposite, or something like that anyway).

People usualy use a trim switch for video/photo, thus i suspect it is only one channel controlling video/photo, but i could be wrong. Unfortunately i don't know how to program a trim switch or a virtual channel so i can't help more. I hope one of the expert users can be more helpful.

Thanks for the input. I played around with different scalar values but without successs. The camera either worked or not but I never triggered the photo function. Here are the lines that enable me to switch the camera on and off using a trim switch:
