"" 2.8" inch mit Touchscreen TFT LCD Display ILI9341 Arduino AVR CP11005 "" is an parallel driven LCD ! not an SPI !
its not supported by the PiCromite but see here:

This display uses a 16-bit parallel I/F so not really do-able in the Pi and in any event Grogster's board doesn't have any connections for DB8-DB15.

Peter,

what kind of Display are you using in the post from 31. August?
Do you have a source where to buy it?
