When I was in China last year I sourced a couple of small E-ink displays (GDEH0124S01) through Taobao. They were simple ones with 8 14 segment characters. After some searching on the Chinese website from the manufacturer I found the datasheet. It was by all means not complete and a lot info was missing. After a bit more searching I found the controller used is DM130120 and its datasheet tells a bit more…
I made a PCB quite some time ago, but due to personal matters, I hadn’t the time to solder them up and write some code for it. A couple of days ago I soldered the PCB and fired up the compiler. After struggling through both of the chinglish manuals I converted their pseudo code into something the compiler and the micro understands.

I like the font you used
Thanks
With this Font it feels more Paper and Pen style writing.
Looks like the same display as this one, might save on that order of 10k :) https://www.aliexpress.com/item/1-24-inch-Flexible-Bending-Segment-E-Paper-Black-White-LCD-Display-Screen-IIC-Interface-TT30120/32782113915.html
I bought from him :) but it appears he was just relaying the order to the manufacturer.
Never trust stocklevels on aliexpress ;)
