Input PWM Signal to Trigger Aux Functions such as Emergency Motor Stop?


I have an auxiliary parachute system setup on my copter. I was looking for a way to take the chute deploy PWM signal as an input on the pixhawk to enable motor emergency stop. Alternatively, take that same signal and trigger arducopter’s own parachute release with an output to the chute.

It is important to me to have an alternative rc receiver in this situation.

Is there a way I can make this happen?


You can assign RC7_FUNCTION (in) to parachute.

How would I get an independent PWM signal mixed into the RCin SBUS?

I guess I could get 2 of these and splice in the PWM signal to the SBUS RCin, but that seems silly when the pixhawk has digital/analog I/O pins
