It looks like all of the available GPIOs on the BeagleBone can be controlled with the PRU, albeit with a 4X penalty. Some timing info here: http://hipstercircuits.com/?p=489 With that said, the BeagleBone with the Adafruit Proto Cape (http://www.adafruit.com/products/572) is a cost effective way of getting access to all of those GPIO pins from the expansion headers on the BeagleBone with hard realtime capabilities for about $100. ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
