Thanks for the reply, that's great info! I'll keep an eye out for the VCOM stickers, I had no idea that was a concern.
The waveshare e-paper screens I'm using come with some decent sample code for driving them, and I just found this Rust implementation that looks interesting as well https://github.com/caemor/epd-waveshare.
I do agree with you though that the idea of driving them directly with the waveforms sounds quite fun. I've seen some interesting stuff online where people have been customizing the waveforms to get even more performance out of them (maybe partial refresh would be fun to look into as well).
As someone who's only exposed to embedded development in a hobbyist way, that epdiy repo looks quite useful, thanks for linking that.
Now to find the time to add on yet more personal projects :)
