How can I learn PX4 software better?

[serkan]

Hello everyone, I want to understand the PX4 system. My goal is to understand the system better and write my own Airframe. In the system I want to write, there is a motor connected to the FMU port for 4 drones to fly. And there are 2 motors connected to the IO port for the rover part, apart from these, I need to drive 3 servos for camera control. My goal is that while the drone is disarmed, the rover part will be activated and the commands sent to the engines used for the rover part will be sent. I want the rover part to disarm when the drone enters the arm state. What kind of progress should I make with this code? How can I learn the system better?

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
