Mir ist bewußt das es abhängig vom verwendeten Modul ist. Deshalb auch die Frage wofür YP,XM,YM und XP steht. Die 2.4'' TFT Module sind ja prinzipiell alle gleich. YP und XM sollen laut Touchscreen.h Doku an Analog Ports (die bereits belegt sind A0=RD,A1=WR,A2=RS,A3=CS und A4=RST) und YM und XP an Digitalports (D8=LCD_D0 und D9=LCD_D1)
