Dah Rules!

  • The selected processor must support all of the I/0 natively ie. no I/O Expanders.
  • There are more out there, but I own these, with the exception of the Pi.
  • The processors to be in the selection are:
    • Ardunio Duemilanove
    • Ardunio Mega
    • TI Stellaris Launchpad
    • Raspberry Pi
    • Beagle Bone
  • The Solution must be integrated with the Radio SubSystem or RSS.
  • There must be two sets of protocols developed.
    • Between the Control Head and the embedded processor.
    • Between the embedded processor and the RSS.

The Winners and Losers and Why?!

  1. Does not have enough I/O.
  2. Cost too much for a small job.
  3. I feel the Pi is over kill in this situation. But you might like it.
  4. The Mega has all of the power that you need.
  5. The Stellaris is my personal choice but, its a little heavy handed.

 

keep tuned in more to come
