Can any LCD be used? Because I’m a scrap junky and see little LCDs for printers and stuff all the time. Is it feasible for this sort of thing to be used without much trouble? Or is everyone purchasing specific LCDs with open APIs or what have-you?
Take a look in the wiki under LCD.
There you’ll find all types of LCDs that are currently supported.
