Result.
Success.
Call it what you will.
See that little blue square?
I drew that. It seems the LCD init routine was working all along - it just wasn't visible because of the backlight problem! Put 9V onto the backlight (check out the PP3 connected to the VIN pin at the top of the photo) and it all works perfectly.
So at least have a working solution for now, keeping the PP3 connected to make the LCD viewable. Obviously, in time, we need to be able to get the whole thing running from a single 3.3V source. But that's a problem for tomorrow. Today, we've got some graphics drawing libraries to build!
