Hy, i buy from amazon THAT 2.8 TFT display
Buy i have a problem:
i'm using that code whit adafruit librarys:
#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_TFTLCD.h> // Hardware-specific library
#include <TouchScreen.h>

#define YP A2 // must be an analog pin, use "An" notation!
#define XM A1 // must be an analog pin, use "An" notation!

#define XP 7 // can be a digital pin
#define TS_MINX 173
#define TS_MINY 146

// For better pressure precision, we need to know the resistance
// between X+ and X- Use any multimeter to read it
// For the one we're using, its 300 ohms across the X plate

But if i use only touch screen or only LCD the single things work fine, but when i try to use touch and LCD i can't read position.
I try to change bits inside the touch class but dont work...
I'have attached the model pic and his pins
