I'm working on an embedded project (basically just leds and uarts, nothing crazy), but my flash space is pretty limited (64k) and ram isn't much either. (kbin.social)

I'm working on an embedded project (basically just leds and uarts, nothing crazy), but my flash space is pretty limited (64k) and ram isn't much either.
I want to experiment with embedded rust, but I also don't want to reimplement ST's register layer (low level drivers I guess).
Any neat tools out there to sort of wholesale convert C to rust?

There's HALs for various processors - e.g. https://github.com/stm32-rs/stm32f4xx-hal

Those are pretty great!
Hopefully the implementation is low level. When I was writing my C version I had to ditch the ST HAL for low-level drivers. That thing is a hot mess, esp when you're trying to cram a bootloader and app into 64k.
