How to emulate a Prop2 on a DE2-115?

ersmith

Are there any instructions for this? I've got the DE2_115_Prop2_v7.pof file from the Feb 2016 release, and I can program it into the DE2-115, but PNut can't seem to find the Prop2 on any COM port. Which GPIO pins should my PropPlug be plugged into?

Eric, I assume you don't have the Parallax adapter board for the DE2-115 since there are for Prop Plug pins on that. There is a schematic for the adapter board in one (or more) of the old P2-Hot zipfiles but I don't have any of those files on any of the computers I have with me. If I can find it, I will post it. It should at least show what pins map to the Prop Plug pins on teh adapter board. (maybe?)

I've never connected my DE2 without the adapter board.

Thanks, the adaptor board is what I needed, and I managed to find my old one (for some reason I had the prop-plug connected directly to my DE2-115 before). Tubular, thanks for the link, the documentation there was very helpful, and I've managed to get the all-cogs-blink demo working.
