    I've been wondering how to load things in a LCD graphic display. I know how to use most of the pins on the displays. But I don't know how to use the the inputs on them because I don't know what kind of data to give it. :confused:

    Could someone tell me what kind of data?:)

    If you have the spec sheet on the display, it should detail the exact nature of the driving signals. You use logic levels to turn individual cells on and off.

    The cells are like pixels. Each cell is either "on" or "off." You use a combination of cells to make signs or other characters.

    You should research the different kinds of LCD displays, some have all the interfacing you could want and you send them serial data, some you send an address to turn on or off a cell. The more complex the display the more likely you'll need to send them serial data of some sort.
