Is it possible to implement R/C channel passthrough to PWM outputs that aren't in use on the selected airframe? My specific planned use case goes like this:
- 16ch SBUS R/C input (FrSky X4R-SB)
- Quad airframe (PWM 5 and 6 unused)
- Separate gimbal (Feiyutech Mini-3D) that takes PWM input for operating mode and camera pitch
What I would like to do is use PWM 5 and 6 outputs of the Pixracer to control mode and camera pitch on the gimbal, using two RC channels not mapped to any PX4 function. Essentially this makes the Pixracer additionally function like an SBUS-to-PWM decoder.
If it's possible to make a configuration like this already, I'd much appreciate a hint where I need to look - a search of the existing documentation didn't reveal much, though maybe I'm not thorough enough. If not, could such a feature be implemented?
