Ok so SSD1289 is the controller, but by the look of the chip it also contain the XPT2046 chip and since it has pins maked D0-15 dose it mean it only can be operated in PPI mode or can i use say one of the pins together with the CS WR RD RS pins to get a 5pin layout that makes it run in SPI?
Any clues?
What determines the configuration of the pins the LCD controller the separate XPT controller wich seams to be SPI operated or do i need to figure out what pins goes were by reverse engineering?
