@Disasm @officialdarksheao can I assign this task you you?

I have environment for building firmware for STM32F1xx (docker image and a lot of config/scritps). Do you need it or you has own idea or development?

@glitchcore I do not see any Rust code in this repo at the moment, so I don't know how to add a build environment right now. I'd like to play with Tock OS first to see which components it has and how to build them.
Other than that -- feel free to assign me.

I suppose add Rust support first and then write some code
