From: Clem Cole <clemc at ccc.com> Yeah, an Arduino as the USB to T.ls would make this pretty trivial as a "general" solution. I'm a year or two behind in Arduini -- do you mean there are versions that realistically let you use the USB port as more than just serial I/O? That would be super sweet! That said, the RPi should be able to support it without anything other than the leds and switches added to the AdaFruit breakout board, I have. Don't get me started on the RPi! By the time they got around to shipping me what was by then an off-rev board I was so pissed I cut it in half with a chainsaw. John Wilson D Bit
