Here is how we have our lights, camera, and hand controller set-up in QGC. I made some changes from the typical set-up to get the mapping closer to something with which I am familiar.
I have control over my Lumen LEDs the way I went them on buttons Y and A. And I can use the Back Button for Manual Mode, the X Button for Stabilized, and the B Button for Depth Hold.
I use the Start Button to toggle the Arm/Disarm function. Plus I can use the up/down touchpad to gain up/down. Touchpad left-right is currently disabled.
The problem is that I have no control over camera tilt up/down on the index finger buttons on top of the controller, and I’m fairly certain I screwed up the camerasetup. Can you provide any feedback on that?
