Chinese TFT SPI 2.8'' display as touchscreen

@David : I actually didn't check that the picture was the same as my display, sorry.

@6v6gt : Thanks, I tried that. I wired as in the ino code :

#define CS_PIN  8
// MOSI=11, MISO=12, SCK=13

//XPT2046_Touchscreen ts(CS_PIN);
#define TIRQ_PIN  2

But all I get on the console is : "Pressure = 4095, x = 0, y = 0"

Did I miss anything?
