Happy to see more stuff coming out that could bring aware to Nim as a viable tool for embedded software!
Personally, video tutorials are not really my thing, but some people do enjoy them. I think most youtubers try to aim for 10-ish minute videos though, maybe cut it up in 2-3 parts next time? Just a suggestion. And finally some self promotion :) Check out my tool for generating nim modules for register-level programming of ARM Cortex-M: <https://github.com/EmbeddedNim/svd2nim>. As I mention in the README, it's sort of experimental, mostly because to my knowledge not too many people have tried it out. So test it and let me know if it works for you and your stm32 target. I have successfully used it to program clocks and a blinky on a SAMD21 (cortex-m0+).
