    Do you have a link to the data sheet for this module? Or any link for that matter?

    It does not look to be a Parallax product.

    It looks like Adafruit has a display with that controller: http://www.adafruit.com/product/1651 and they link the controller datasheet: http://www.adafruit.com/datasheets/ILI9341.pdf

    Code dosn't seem to work I know it is ILI9341 GPU..
    Banging my head against the wall with it, written code to just get it to light up a pixel or anything.
    Followed the ILI9341 data sheet page 33.
    Turn CSx High initialize state.
    1. Turn CSx low telling it to get ready for Transfer.
    2. Turn DC Pin (Low = command High = Data)
    3. Put Data onto Mosi pin starting with MSb7
    4. Turn SCL Pin Low then High tto move bit to ILI9341
    4b. Repeat 3 and 4 for each bit of the Byte
    5. Turn CSx High to signify end of Transfer.
    Repeat 1 - 5

    Nothing........................................... ...........
    Anyone using this module PLEASE HELP CODE ect

    Figured it out!
    It seems, and why I don't know, that the wires I was using (Hard wire) were not good. I purchased some jumper wires from Parallax and it works like a charm.
    I'm using sebastian1989 ILI9341 driver http://forums.parallax.com/showthread.php/154703-Read-bmp-image-from-SD-to-Display-ili9341.-Done-in-spin-but-very-slow?highlight=ILI9341
    Hope this helps others thanks to sebastion for the driver, now I can start figuring it out with the datasheet..
