I bought a nice SparkFun Graphic LCD Serial Backpack and a Graphic LCD 128x64, which excitingly arrived yesterday.
I got the backpack attached to the screen, and connected to my Arduino, and so far have a nice bright blank screen, but no response to serial comands
Ran out of time then, so no idea what I've got wrong yet. I rebuilt my robot a bit to make the arduino extractable so I can play with the screen in isolation. For now assuming I've done something wafty, so will cross fingers and have another stab this evening. Expect questions
I think it's something to do with using SoftSerial, at 9600, when the backpack defaults to 118000, so I'll tinker about with configuring it using the real serial io pins to talk at 9600.
