I have some docs on how to drive one of those spare eBook reader eInk screens from my reverse engineering adventure of PocketBook: http://linux-sunxi.org/PocketBook_Touch_Lux_3 I've mainlined the support for this PocketBook to Linux 5.7. Though if I was doing this project I'd re-use the PocketBook board too, instead of building new HW to drive the screen. Driving the eInk signals on larger screens requires a very fast and precise signalling, and you also have to generate around 5 different voltages for the screen. And the board can already do that and the SW (bootloader, kernel) is all open source, so there's no downside. You could drop the RPI. |

Here’s my ipython notebook that I used to extract LUTs from an eInk dev panel [1] which eInk support declined to give us the LUTs for.
I’d stopped after I managed to display some images but I now I have a reason to revisit and play with the PocketBook Linux. Thank you!
