Also I found oloh after looking at videos about android where Jeff Sharkey mentions he used zebra crossing in his compare everywhere application to decode bar codes for comparing products.

new google code project

I created a google code project for the code for the cw or morse code keyboard. It's called morsekeyboard. The AVRopendous works great as a USB keyboard. Decoding the dits and dahs is next.

Or maybe this might work best since I can develop for AVR chips with gcc. It's the AVRopendous http://code.google.com/p/avropendous. Cost is $20.

It comes with keyboard controlling firmware too. As you can see it types keys when he grounds the pins.
