VOXL FLIGHT connection to LuxF7HD

[mirasul]

Can someone guide me in this process? I am trying to use a Betaflight flight controller instead of the PX4 onboard flight controller. Is there a guide available for this type of setup?

It is not something we have direct support for since the flight controller is built in.

Here is how you connect VOXL to an external flight controller: https://docs.modalai.com/how-to-connect-voxl-to-pixhawk/

The normal UART is not exposed on VOXL Flight, so you would have to modify the code on VOXL to use a different UART

Thank you for the quick reply. I have successfully setup the wiring portion. I was wondering if there is a guide to show me how to modify the code to use a different UART?

You will need to change the code in voxl-vision-px4 to use a different UART. I don't think betaflight supports mavlink though as a control mechanism. What are you hoping to connect between VOXL and betaflight?

LuxF7HD is a betaflight flight controller. https://rpg.ifi.uzh.ch/docs/IROS18_Falanga.pdf developers from the university at zurich were able to bridge the betaflight controller to the onboard computer. we think we have the wiring portion done, but we need to somehow send the parameters changes from the voxl to the betaflight controller via a serial port. we are using serial port j10012 currently. please let us if you have any ideas on how to bridge the two
