Hi Jeff, and thanks for the response.
Although not exactly what I’m looking for though. Sure, the response is technically correct, but is really “here is a link to the massive Cortex documentation, good luck” really the best answer to what is clearly a beginner question…? Just saying…
The best pin documentation I’ve found for the Cerb40 II is on this page I get to if I follow this link-trail:
GHI -> Catalog -> System on a Module -> Cerb40 II -> Resources -> Cerb-family -> FEZ Cerb40 -> click “This page” at the bottom and come over to wiki.tinyclr.com -> Click the redirect link.
Needless to say, I don’t remember this path every time, so there is a lot of clicking back and forth. That page has a decent table with the pin layouts which I assume is applicable for the Cerb40 II as well.
And it is from that table that it isn’t crystal clear to me which ones I can use as GPIOs.
