Hello,
I spend the last few days on making a GUI with a Homescreen and some under menus.
This is my first Project where I try to avoid to use the delay function and do all the timings with
millis. For a better overview I just post the Setup. On the UNO (Original) everything works perfect.
But due to the lack of unused pins a need a Mega to get all the Hardware connected. And thats my Problem:
Connected to the Mega( Not Original, link at the End) I only get a white Screen. I´ve got some Serial Print for debugging on each button on the Screen and it seems that the Touch is working properly.
The diagnose Sketches from MCUfriend are working correctly. The Chip is a 9341. So I think it need something to do with my Sketch..

tft.reset();
tft.begin(0x9341);
tft.setRotation(1);

}
Is there a point I´m missing where I need to say the TFT that it is mounted to an Mega?
