There are many posts about this same problem, and I have looked through quite a few of them. Unfortunately, I seem to still be stuck. I am using UTFT.
Here is the display I picked up: http://www.ebay.com/itm/291168396956?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
According to the page, the display driver is an ILI9341. However, the screen uses a 16pin parallel interface, and I think the ILI9341 is a serial interface. So that's probably wrong.
I have tried the SSD1289 driver with no success.
So, has anyone out there tried this display, and gotten it to work?
The ILI9341 itself supports both SPI and parallel mode.
Manufacturers of these shields, however, generally only include one of the interface types so they can charge a higher price for the SPI version, which in fact costs them less to make.
So you should find the right library for it, just bare in mind if you write ILI9341 on UTFT it will most likelly default to the SPI variant.
Try to find a big manufacturer that uses the same controller on their shields. I am not sure if adafruit does, have a try.
If nothing else works, just get a similar 16bit screen set up and change the initialization commands as per datasheet: it can be tedious, thats why you should always check the model number before you buy.
Last but not least, ask the seller if they have a demo. Often they point you to the right model to use with a graphics library, if not theill give you some code which contains the init commands, so it makes it easier for you to modify one of the existing UTFT liraries to fit your display.
Good Luck, perhaps someone here has the same TFT and can give you some clue, fingers crossed
Looking at board and spec my gues is SanSmart device which in turn derives from the Ninteno DS teplacement..
The big connector is the parallel interface and the other is the touch screen interface
The circuit diagram for the actual shield supplied by Sansmart probably go to Trade Spoting on ebay they have store + pdf down loads.. of cct's demo's etc..
