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.

shure we can do that. i think 25$ for a touchscreen can't be beat. paul

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: http://www.ebay.de/itm/3-2inch-lcd-module-with-touch-panel-bulid-in-SSD1298-controller-PCB-board?item=170863074266&ih=007&category=26206&cmd=ViewItem
