- Prepare a Link or Document to help understand if possible
- First, ask the question on the Slack or create a Github Issue!
- If you take over 5 minutes for the question, please continue in Slack or a Github Issue.
Q.1 : Issues while testing beta v1.13 blocking Fixed Wing Test Flights - Jakob
-
Airspeed Sensor not calibrating
13.0rc1 airspeed calibration not possible · Issue #19772 · PX4/PX4-Autopilot · GitHub -
Servo direction not working in stabilized mode
13.0xx testing. Hi Would be interested to hear how many fixed wing users do testing. I experience issues with rc1. (i.e airspeed, servo direction in stabilized mode if orientation of pixhawk is not default. Quite a big number of parameter do not get set to the default value even after a full parameter reset. I have not seen this from 1.11 to 1.12 ( I am testing on holybro 4 and 4 mini)

PWM test got removed
- Was removed from IOCTL cleanup PR: pwm ioctl cleanup by dagar · Pull Request #18944 · PX4/PX4-Autopilot · GitHub
- pwm.cpp: remove the test example by hamishwillee · Pull Request #19587 · PX4/PX4-Autopilot · GitHub
- Testing the PWM output currently is tricky: Need to enable Control Allocation & Go to QGC & Test the output (publish
actuator_outputs
) - Answer: Can use “motor_test” command to test the output now!
