No PWM output on Pixracer

PX4 Autopilot Flight Controllers
#1

I’m running a Pixracer with ArduPlane V3.7.1.

I was unable to get the servo output working so I connected Ch.1 to the Arduino to read the raw PWM output.

Here’s what that looks like:

Here’s what I’ve done so far:

  • :white_check_mark: Connected external 5V power source on output rail
  • :white_check_mark: Configured plane as AERT
  • :white_check_mark: Set MANUAL mode
  • :white_check_mark: Set ARMING_REQUIRE=0, for good measure
  • :white_check_mark: Confirmed RC transmitter values being read in groundstation

Expected output:
The PWM value from the Roll channel on my transmitter will be sent to Ch1 of the output.

Measured output:
PWM value = 0.

Would appreciate any help here.

Hi @rock you would probably be better to discuss this on the ArduPilot forums as this forum is generally for the PX4 flightstack.
