Topic: 2.8" TFT Touch Shield (Read 2426 times) previous topic - next topic



I just got the new 2.8 TFT Touch Shield from SeeedStudio:
First I used the sketch below which worked great. Then I added a few Rectangles and
more circles but suddenly the Screen stayed white even after disconnecting from the Arduino
and reattaching.

I then just tried the example sketch but the Display stays white....
I tried several things but still it won't change anything... Is the Display already dead?

// Draw Circles - Demonstrate drawCircle and fillCircle APIs

#include <stdint.h>
#include <TouchScreen.h>
#include <TFT.h>

#define YP A2   // must be an analog pin, use "An" notation!
#define XM A1   // must be an analog pin, use "An" notation!
#define YM 14   // can be a digital pin, this is A0
#define XP 17   // can be a digital pin, this is A3

void setup()

  Tft.init();  //init TFT

  Tft.drawCircle(100, 100, 30,YELLOW);
  Tft.drawCircle(100, 200, 40,CYAN);
  Tft.fillCircle(200, 100, 30,RED);
  Tft.fillCircle(200, 200, 30,BLUE);

void loop()



I know what you mean. Actually that just means that one of your shapes' edges are out of bounds. Try displaying your shapes inside the screen borders.
