I need help regarding assigning of multiple functions on a single channel of RC i.e for instance, how camera gimbal control i.e. pan, tilt and zoom can be used using a single channel. As per my understanding, this is possible by combining it with some other channel i.e. a single channel may be used for pan, tilt and zoom whereas some other channel assists in assigning these functions. The same functionality is available in DJI systems (A3 flight controller/Light Bridge 2) and it makes the camera control simpler. The Scroll wheel can be used for pan, tilt and zoom with push buttons assigning all three controls on scroll wheel. I would like to add this functionality in herelink and other RC systems for easier camera control. This may be more related to assigning of servo functions in ARDUCOPTER/MISSION PLANNER; yet it would be of a great help if someone can assist in this regard.
Thanks in advance
