Driving a motor from the I/O PWM Out port of the PX4 board

Hello, I have a PX4 card and I installed the PX4 Autopilot software on it and use this system as a Quadcopter. My goal is to use my drone in offboard mode. Until this part, I controlled my drone via ROS2 in offboard mode. but as an extra, I have 2 motors and 1 motors to control the camera. How can I use these motors? I control the drone’s motors from the “FMU PWM OUT” port. Can I control other motors from the “I/O PWM OUT” section? My first question: How can I give PWM output from the I/O PW…

How to use "FMU PWM OUT" and "I/O PWM OUT" simultaneously on PX4 board

Hello, I control the drone’s motors using the FMU PWM OUT port on the PX4 board. How can I give PWM output using the IO PWM OUT part while the FMU PWM OUT part is working? My purpose: I want to control 3 more motors besides the motors required for the drone to fly
