Julien @ hackaday.io build a custom board to control e-ink display. He writes:
The idea is to control an old broken kindle 3 eink display with a FPGA. I started looking at http://essentialscrap.com/eink/waveforms.html and http://spritesmods.com/?art=einkdisplay since eink constructor is so secretive that you can’t find any information. I got some success with a stm32f4 microcontroller but was disapointed by the poor performance (low refresh, black and white only). So I decided to do something better using an FPGA and some memory, I started with the ice40 Olimex board https://www.olimex.com/Products/FPGA/iCE40/iCE40HX1K-EVB/open-source-hardware.
