I’m building a Hexacopter for a School Project with a PX4 2.4.8. I have a Camera gimbal for which I need the PWM Output (2 Channels) and a Retractable Landing gear (only 1 Channel) with either a Relay Output or a PWM Signal. How do I know which AUX Ports will be used?
Passthrough can be used on any output. And rather than use Passthrough it’s better practice to assign the input even if its the same channel Input to output. It accomplishes the same thing but better educates how Input and Output are really completely separate.
For example SERVO7_FUNCTION 1 (passthrough) and SERVO7_FUNCTION 57 (RCIN7) accomplish the same thing. But I would suggest the later is better practice.
