#ARDUINO UNO PINOUT MAPPING SERIAL#
With the following code I succeeded in using this shield on the Mega: /*** COPY-PASTE from Serial Terminal:Ĭonst int XP=8,XM=A2,YP=A3,YM=9 //240x320 ID=0x9341Ĭonst int TS_LEFT=116,TS_RT=936,TS_TOP=68,TS_BOT=891 The “TouchScreen_Calibr_native” example from the named library told me, that I have to use different pins for the TouchScreen on the Mega than on the Uno: XP=8, XM=A2, YP=A3, YM=9. But in my project I need a Mega 2560, so I tried to port an example to the Mega. I found that the Mcufriend-library-examples work with this shield, as long as I have it plugged onto an UNO. I have this ( link) TFT-Colour-Device (driver chip: ILI9341) with a touch screen. I try to get acquainted with touch screens.
