I've created code to drive the E3 LCD-Key using SPI.
The E3 LCD-Key.
http://www.e3-keys.com/english/sb.htm
Is a 64x32 pixel LCD display with RGB backlighting.

Tom's code for the ScreenKey was a huge help.

The project can be found here.

This is my first published project, so be gentle.

Good job, Jim. I'm thinking I might add a Tiny13 to the Screenkeys I have and turn them into SPI devices.

Cheers,

Tom

That was my thought at first. Unburden the main processor and offload the bit-banging constant clock stuff to a second chip. But I also didn't want to increase the parts count.
I'm going to port my original code from the mega644 (way overkill) down to the Mega168 and see how things go.
SPI was so much simpler to work with than the custom 12-bit.
