If you read the previous article here about the progress of the tele-presence robotic avatar that Duane is working on, I think you’ll agree that this one sheds a bit more light on where he’s coming from and how he is approaching his endgame. Let’s check in real quick – regarding how he seems to blow up his GPIO:
In order to deal with my exploding GPIO problem, I didn’t go to group therapy. Instead, I purchased two Gadget Factory 16-bit I/O buffer wings when I ordered the Papilio Pro. They cost a lot less than a new FPGA board and are completely transparent to the FPGA configuration. The image [above] shows the Papilio Pro, one of my I/O buffer wings, an LED/button wing, and a breadboard with a switch and four LEDs.
Before getting back to work on my robot avatar, I wanted to give the Papilio Pro a quick run-through to see what changes I might need when migrating my existing designs from the Avnet/Xilinx Spartan-6 LX9 board.
