A new driver for the Badger2040 e-ink, or EPDs hacking and waveform LUTs design.

"The world of e-paper displays is one of the most undocumented you can find: this is the unfortunate side effects of patented technologies, as there is a strong incentive to avoid disclosing useful information, with the effect of slowing down software progresses towards programming these kind of displays. "

That's a startling remark to make. I mean, like if I wanted to control OLED display waveforms, there's not exactly a massive stash of documentation about that. It is just that nobody really needs to since OLED drivers are hugely commercially successful that standard controllers drive them perfectly whereas the niche market for black white slow panels ends up with things less than satisfactory. I'd love to see evidence for claims like "slowing down software progresses towards programming these kind of displays".
