the Kent Displays EVGA Evaluation kit sports a 160x120 pixel bistable ChLCD. This means that it only requires power to change the image on the display, not to maintain it. You may have heard of this other company with a similar technology. However Kent has a product that is in the reach of the casual hobbyist whereas Eink does not.
update rate
These displays take about 1s to fully update. They use a 'wipe' fade just like the news did many years ago. Read on for why this wipe effect manifests itself (or just skip to the driver section now). To give you an idea of what this update looks like please check out this grainy video. As always I have provided this video with the assistance of my trusty CVS Cam.
You may recognize the sideways logo in the movie - it belongs to boston engineering. Also note that I took some creative license with the logo by not including the text "Boston Engineering" in the same place it shows up on the website. Yeah, someone mentioned it to me...
device driver
i have decided to try to write this as my first linux device driver. if it ends up working i'm sure it will be sloppy, inefficient, and full of bugs - but hey it's my first one so i'm not too worried about that. I'm aided by a wonderful and free book O"Reilly Linux Device Drivers 3rd Ed.. You should check it out too and enter the exciting world of device drivers.
I have a basic, no frills driver working but I don't think its worth posting yet. I'm tied up in so many projects at the moment that I can't break free and update it just yet.
