Greg, You know what. If I were you, I would get a Beaglebone black or green, and make learning about it your favorite hobby. This way, you could experiment with various things, until you're happy with what you end up using.
If memory is serving me correctly yes, you're using a blue. Yes, yes, but the hardware is largely the same, and most if not all the software will be exactly the same. So yes, buy a beaglebone, take it home, and start experimenting. Then I would probably not worry about HAVING to have hardware connected up with it. There is a lot you can do by experimenting with software only. How, and where to explore the GPIO subsystem. Which will then lead to being able to tell if you've configured your overlay file at boot correctly. etc, etc. On Sat, May 20, 2017 at 6:01 PM, Gerald Coley <gcol...@emprodesign.com> wrote: > I decided not to copy what was in the TRM into the SRM.
