I've tried this on a graphic LCD I got from here: Blue Graphic LCD Display 128x64 Technical Data with no luck.
It's a "B" style pinout, and although the LCD lights up and I get contrast adjustment, I get no actual graphics from the Arduino. I do get a slight flicker running down the screen with a medium contrast, but that's it.
I've triple checked the wiring - the only thing I'm not sure of is the resistor to the backlight, but it's 180 Ohm (in the middle of the range given), and I can't see how that would affect data. Any clues?
I'm using a diecimila with Arduino v0010.
Thanks!
