Most everything I've got planned involves the Atmel silicon onboard, the ATTiny 2313a.

The ATTiny is the (128 Byte) brains of this setup - it has a Universal Serial Interface which I am using as SPI. For the early demo, the first thing the board does is program the LTC6903 to get 2x VGA frequency (target: 25.175x2 MHz).

Most of the next work will involve the ATTiny. Here's the fun I've got planned.
