Yeah, those are all included in the configuration.h file
What I don't know is where to configure it for the 20x4 LCD I have. All I get out of the display are two lines of solid squares, with some characters visible when I press one of the buttons on the keypad. Sometimes I'm not sure I'm actually turning the contrast trimpot on the board, but regardless of that I should be getting all 4 lines of the display, not just two.
