I would really like to see more work on improving the use of Nim for programming microcontrollers. I stumbled on to https://github.com/elcritch/nesper recently and it looks neat, but I had issues getting my code to compile. Improved support for other MCUs like the esp8266 and atmega32u4 would be really cool and useful. It would be nice to have Nim as a higher level alternative to micropython or lua in the embedded world (your only other real alternatives being C/C++ or Rust).

I also found this https://disconnected.systems/blog/nim-on-adruino

Nesper author here, unfortunately I haven’t had time to fix the compile issues on all the esp-idf branches. Please feel free to file an issue as I don’t use es-idf/Nesper often now but I’ll respond to issues. The main branch should be more stable too.

I’ve been moving development to Zephyr RTOS since it supports many more boards and is more stable. I’d recommend trying it out but note it’s a WIP. I haven’t figured out templated examples yet. I’ve covered lots of api areas but not all. My goal is to make it into a broad MCU platform for Nim — Nephyr: https://github.com/EmbeddedNim/nephyr

But yah Nim can run on most anywhere you can compile C to. Some people just got Nim CMSIS working. I’m hoping to get more people involved at github.com/EmbeddedNim project to support more mcu’s. Testers are welcome!

That's awesome. I didn't file an issue yet but I was hoping to try it again soon and get a better idea of what's going wrong first.
