So I’ve set up a test bench, that includes a load cell that I’m using to measure thrust from a quadcopter. I’ve been able to control PWM signals via the actuator panel within QGroundcontrol, by setting the aux1-4 to Constant Min and manually adjusting the Min value. Information can be found here . Th…

I’m assuming you’re using PX4 (and not ArduPilot, otherwise ask in discuss.ardupilot.org ). You should be able to use the command MAV_CMD_DO_SET_ACTUATOR , e.g. in pymavlink. Or in MAVSDK-Python it would be: http://mavsdk-python-docs.s3-website.eu-central-1.amazonaws.com/plugins/action.html#mavsdk.…

Yes, correct, I am using PX4. Thank you, I will dig into your recommendation!

hello, I also want to directly control the pwm signal and now i am using the pymavlink, I am able to send command to arm and disarm the vehicle, but when i want to use MAV_CMD_DO_SET_ACTUATOR it throws an error AttributeError: module ‘pymavlink.dialects.v10.ardupilotmega’ has no attribute ‘MAV_CM…

Hi, I have also run into this with pymavlink: AttributeError: module ‘pymavlink.dialects.v10.ardupilotmega’ has no attribute ‘MAV_CMD_DO_SET_ACTUATOR’ have you found a solution? Does anyone know if you can change dialects to pixihawk/px4 in pymavlink?

Can I control PWM signals to esc directly via Mavlink?

Hi, the common dialect also did not work, but I was able to find a solution by passing it the integer 187 directly.
