New Kent Display

From Public

This is the new display combined with my QR encoding library, all at http://github.com/tz in the sparkfun repo, in the qrkentlcd subdirectory.

The display holds the image with the power off. This is 4x (one QR square = 4x4 pixels).

It uses SPI, 1 is white, 0 is dark blue.

One big downside is that it is SLOW. It takes over a second to update the display. It isn't going to do fast animations (or rpm updates from my harley :(, it doesn't have adequate sub-screen update). But for things like this - persistent and high-resolution, high contrast, sunlight readable, it works very well.

It is also a bit pricey.
