Modifiying software

PX4 Autopilot VTOL šŸš

Hello everyone, my name is Roberto Dominguez,
and Iā€™m developing a VTOL Tiltrotor prototype using a Pixhawk flight controller using the QGroundControl platform.
My prototype looks a lot like ā€œE-flite Convergenceā€ so I would like to know how I can modify the software that incorporates this model, to fully adapt it to my prototype.

Thank you very much for your time.

Hi Roberto,

Depending on a few specifics you can probably start by selecting the Convergence airframe to configure your autopilot. Many things can be configured as parameters. The ā€œE-flite Convegenceā€ airframe configuration is here: https://github.com/PX4/Firmware/blob/master/ROMFS/px4fmu_common/init.d/13012_convergence

If you get to the point you need to change the mixer or actual control code you can duplicate that airframe with your own, change the mixer, etc.

The code that handles the tiltrotor transitions can be found in the vtol_att_control module. https://github.com/PX4/Firmware/blob/master/src/modules/vtol_att_control/tiltrotor.cpp
