I bought a cheap Tochscreen from China on ebay.
After some try and error i was able to get it running. It is working quite well.
I had some problems with the touch module using the i2c on J8/9. So i had to use some gpio pins on J5A/J5B.
I used the UTFT Library from Henning Karlsen as a starting point.
Maybe someone is interested in the code.
here the link to the display on ebay:
3.2 Touch Screen

The pcb beneath the dispay is forcing me to use the 16bit parallel mode of the 1298 controller. i could read out data from the diplay, but i had no reason to do it yet.
i am not capable of getting the display to work in 8bit mode. i can't find the fault and it is driving me mad. they mouted a 74HC573 latch on the pcb to use the 16bit mode with 8 bit input, instead of making it possible to enable the nativ 8bit mode of controller.
