    I don't know much about controllers. The GLCD I'm using is the NHD-C12864WM-09-FSW-FBW-3V3-M from New Haven Displays. It uses SPLC501C controller, which would now be the only one I know *anything* about. I still had to take the output and modify it somewhat.

    For the little image pasted below, here's the code that the software generated:

    So it didn't write *all* my code for me, but it sure helped shorten the amount of time.

    I guess the moral to all this is that there is no substitute for reading (and reading and re-reading) the datasheet until it starts to make sense...
