Hi Steve, Sounds like you have your head in the game.. Smart! :-)
I have no clue how successful the BeagleBone is going to be. But it sure is interesting! It could really be a game changer. I'm going to try hard to get to Wichita and so far I have been able to keep my schedule clear for that week. It could be a very interesting gathering. >>The design is based around a programmable logic device to minimize the impact of incorrect assumptions of how the Beagle Bone Black is pinned out and configured. << Very smart as this bleeding edge stuff sometimes needs different accommodations! :-) Regards, Dave Cole Cole Controls On 4/28/2013 9:56 PM, Steve Stallings wrote: > Dave, > > PMDX is considering just such a product and is trying to > figure out what things are needed for a "real" industrial > control. > > Meanwhile, we are actually working on a "cape" to be used > as a test platform at Wichita.
