Motor control using AUX port

[Sanatan_Biswal]

Hello everyone,
I’m trying to control motor using AUX. Please help me if anyone know how to do so.

You can check this page of the documentation:

Actuator Configuration and Testing | PX4 User Guide

Let me know if this helps.

I’m using quard copter setup and there is no actuator setup.

Could you try one of these solutions? It might depend on which version of the fw you have.

Missing parameters in Motors Tab in QGroundControl

Hello I am using a Pixhawk Mini with PX4 pro-Stable Release v1.13.0 and QGroundControl Version v4.2.3. In the Vehicle Setup → Motors Tab I only have access to Motors Setup, while in the Actuator Configuration and Testing Page in PX4 User Guide Actuator Configuration and Testing | PX4 User Guide there are more parameters like Geometry and Actuator Outputs. Also, the name of the tab is different, I have a Motors Tab while the Documentation Page has an Actuators Tab [image] In the Airframe Tab,…

Getting old Motor tab instead of the new Actuator tab

Hi, I had the same issue too. I use a Pixhawk 4 (FW 1.13.1) connected to a companion computer via serial connection, then over wifi with mavproxy to the gcs, running QGroundcontrol. And I use the generic quad airframe. I had to update mavproxy.py to the newest version and QGCS to the new daily (Oct 20th) version. And I had also set the parameter to SYS_CTRL_ALLOC=1. Then it works for me.

Otherwise you can do it directly in the code changing/setting the value of these parameters:

PWM_AUX_FUNCx

You can add this kind of code into the airframe if you want to hardcode it.

# Outputs
param set-default PWM_AUX_FUNC1 101
param set-default PWM_AUX_FUNC2 102
param set-default PWM_AUX_FUNC3 103
param set-default PWM_AUX_FUNC4 104
