Like many people on this forum, I'm interested in connecting a e-paper display to an Arduino.
But then I'd like something larger than the Sparkfun thing. I want to make a paper terminal for my PC, so I can stare at VIM on a piece of e-paper instead of a big lamp.
I've been talking to MSC - the distributor of Pervasive Displays for Europe - about their displays, and there seem to be 3 methods of control.
- SPI via a TCON board
- An EPSON chip in a BGA package
- Directly via waveforms
I think SPI would be the easiest, but then you can only refresh the complete screen with 1 bit B&W. When typing on my terminal, I don't want to wait for the whole screen to refresh every time I press a key.
The EPSON chip allows you to do partial refreshes with grayscale, but I'm not sure how hard it would be to integrate that chip.
I have no idea what it even means to do waveforms, and if that is possible with the Arduino. The spec for 1 bit is free, the spec for grayscale waveforms is 5500USD.
They also ignored my requests for a price.
If this is even remotely feasible, I would buy a prototype screen, and later a batch to resell to other enthusiasts.
I am a programmer, not an electrical engineer. I did make this PICAXE controller before: http://studl.es/2012/05/diy-servo-controller/
