@krzysztofgawrys just so I understand, why didn't you go with ch32fun for this project?

(Will comment in another message in an official capacity)

This project appears to be eligible for a PID code. All source + hardware sources (easyeda) are made available with PDF schematic, under open source license.

I recommend merging.

@cnlohr
This project started on an STM32 and moved to the CH32 because they are dirt cheap, so the easiest firmware transition was to the WCH SDK,the StdPeriph-style API is nearly 1:1 with what the code already used.

Also, I'm new to the CH32 ecosystem and didn't do my homework thoroughly, I simply didn't know about ch32fun at the time. I'll take a look at it.

Thanks for the review, is anything else needed to get this merged?

@krzysztofgawrys hey, sorry, one more thing I have been made aware of, before approving, we require the source hardware files (which you have) as well as a PDF/image of the schematic and/or embodiment (preferably both). Can you add those to your project?

Other than that, everything looks fine and I can merge.

Please @ me in thread so I can do a quick turnaround.
