I mean, Rust has the massive upsite that it won’t compile in many cases if you fuck things up. Then again, embedded or generally low-level driver-y stuff is still in its infancy in Rust. Relative to C/C++ that is.

There is stuff that you need that has no official Rust support. There is poor documentation and half baked frameworks. There are examples being silently outdated, breaking changes between framework versions, and nighlty-versions from Github mixed in to fix them. And then of course plenty of timing and hardware dependent things you will need to do yourself.

I do this for a living and personally tried to use AI here and there to help me out, but oftentimes it fails miserably. Not always, but very often.
