<![CDATA[Building a Custom Flight Controller]]>Hello,

Wondering if anyone here has worked on a custom flight controller stack not built on PX4, but which still uses Mavlink message standards.

I just started on this effort.

If so, I would like to know where dependencies might lie outside of the PX4 build. What VOXL data pipelines would break? Quite new to Modal's stack.

Thanks!
-Ty

I'd definitely recommend against it.

I'm trying to identify where best it makes sense to run a custom flight controller in the current architecture. I realize I could do something external, but I would like to keep everything just to the VOXL2 using the I/O expander board for PWM output.

I know this is quite a tough question that isn't very well defined, but I would really appreciate any advice if there have been attempts to perform similar things before.
