This is very cool. I imagine the easiest way to have this communicate with the big core would be to via the uart?

I think uart would indeed be the easiest solution, but it need to.use a cable to connect the tx pin to rx pins.

Another solution is to use the mailbox module. Unfortunately this is not really documented, so you would need to read the freertos code to implement the rust side.

A third solution would be to use shared memory, but I don’t really know how to do that.
