There was some discussion here a while back that the Hawkboard uses a different interrupt model that should have less latency, and might be worth a look. The Hawkboard seems to sell for about $150, when they're available. I'd kick in at least $50 for that (maybe more), if someone had time to work on it.
It looks like the Hawkboard uses a very dense connector for the GPIO pins, we might need to come up with a breakout board for it. ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
