Hi David
I am including following libraries:
#include <Adafruit_TFTLCD.h>
#include <Adafruit_GFX.h>
#include <TouchScreen.h>
I am not sure what you mean by "which example name gives a problem"
I get no error message. After Uploading, It does show the the programmed screen first and then the display just turns white after half a second. The display stays white until I download the code again.
The bug seems to be random. As soon I change setting in cursor line for position or size, it may work or not.
e.g. change setCursor to 35,48 as showm here insead of 30,48 and the screen goes white.
In code:
void Screenhome (){
// Taste1
tft.setCursor(35,48);
I tried it with an Arduino Uno and Mega. I tried several Arduinos but it shows the same bug.
Thank you very much for your support.
Here is the whole code:
