This display module apperantly has quite a bit more to it than I was expecting... I was hoping for a simple display that could be used over serial when I picked it up, but that doesn't seem to be the case.
I still want to use this with the arduino, but I can't seem to comprehend how it's supposed to be used. Ideally I'd try to use less than 12 MCU pins to operate it, as well, but I can worry about that later...
It confuses me, because this display module evidently has some sort of internal memory, and I'm not sure how to use that, or to cause text to be displayed.
