TIL about "Charlieplexing", or how to use a reduced set of pins to drive a matrixed set of LEDs. https://en.wikipedia.org/wiki/Charlieplexing

That's going to be funny when you try to make a photograph on a short shutter time. Half the display will be off!

Super common technique. Aircraft cockpit videos usually exhibit stroboscopic effects because of the scan rate of the camera and the refresh rate of the displays, and those are very expensive devices. Short shutter time photos are just not a case I think most displays are designed for.

Question for the people who have used the CH32V003 or more generally WCH, either for hobby or production, what is the current state of documentation and toolchain for these chips? Positive experiences, war stories?

Running Rust on them worked well for me: https://github.com/kpcyrd/ch32v003-demo I had to put in more effort regarding RAM use and flash size, but I managed to fit a game into the 16kb limit regardless: https://github.com/kpcyrd/game-streetcat2026

Very nice walkthrough in the demo readme, thanks for sharing.
