STM32f4 discovery and 3.2 TFT....

Hi all. I was just wondering about TFTs. I have used a 3.2'' TFT on my Arduino before and have seen much use of TFTs on the STM32f4 discovery... The TFT I have in question is a 3.2'' with an SD card slot in the back. Like this one:

http://www.ebay.co.uk/itm/SainSmart-3-2-TFT-TFT-LCD-Shield-for-Arduino-Mega2560-Mega1280-R3-Nano-Robot-/271036654419?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item3f1b0b2353

I am wondering if anybody has used this particular type.. I believe it uses an SSD1289 controller but has different physical connections than other tfts I have seen being used ( like the mikromedia boards for example...)

If anybody has, I would be interested to know.

( It is purely for educational purposes ATM.)

Thankyou.

Steve.

I know this one Clive. I've actually got the TFT connected to the Arduino mega2560 via an adapterboard from seeedstudios. The ITDBGraph16 and Touch libraries work well albeit a little slow on the 8 bit 2560. Very easy libraries to use though. The TFT in question has an SSD1289 driver. I have ordered some female to female jumper wires to connect the board as in the diagram here:

And will try connecting then.

Will let you know how I get on.

( I would like, to start with, to build a simple MIDI controller with a TFT GUI.)

( I can just about make out the peak of this learning curve in some very hazy, smoky distance...)

I posted for the benefit of others, as the eBay link didn't have the technical detail required. Should probably connect via the FSMC.

''Should probably connect via the FSMC. ''

What is the FSMC? ( REM I am a beginner )
