PWM Test results in a jumping PWM Output

1

Hi,

I am trying to run the Pixracer with the actual PX4 Firmware. In order to test the control outputs (PWM Signals) I use

pwm test -a -p 1700

The problem what occurs is that the PWM signals jumps between the PWM DISARM value (e.g. 900) and the test value (1700). I already closed mc_att_control and mc_pos_control to check wether this is the problem. Further I checked if there is any output at the actuator_outputs topic and it is:

actuator_outputs: 900.00 900.00 900.00 900.00 0.00 0.00 ...

It seems as if something publishes a signal via the actuator_outputs and this is in competition with the test signals. Does anyone has an Idea why this happens or which program may cause this?

Best regards,
Nils

I’m getting this. Did you manage to fix it?

Think I found the problem.
