Communicate landing coordinates from STM32F407 to Pixhawk

Hello all, I’m a complete beginner in using Pixhawk but I’ve been using STM32 for a while now.

I’m designing an automatic landing system for my quadcopter using Pixhawk 2.4.8. However, when STM32 gets the coordinates of the landing position, I can’t find a way to communicate them to Pixhawk, let alone use those coordinates to build a path for the drone to land.

Has anyone ever tried to communicate STM32 to Pixhawk before? Thank you in advance.

You need to establish serial communication between pixhawk and your embedded card and parse mavlink messages. This might help.

oh thank man, I’ll check it out!
