Our Arduino Micrometer Project is off and running. We have the speech module up and running, and now the VGA output module. It’s a simple serial interface and only uses two i/o ports. We are using the PICASO QVGA/VGA/WVGA Graphics Controller from Sparkfun – http://www.sparkfun.com/products/10329

The µVGA-II(SGC) is a compact & cost effective drop in embedded graphics engine that will deliver stand-alone functionality to your project. The simple to use embedded commands not only control background color but can produce text in a variety of sizes as well as draw shapes in 256 colors while freeing up the host processor from processor hungry screen control functions. This means a simple micro-controller with a standard serial interface can drive the module with ease.
