Hallo,
ich würde gern ARD SHD 2,6TD Arduino Shield - Display 2,8", Touch, 320 x 240 Pixel, ILI9341 mit einem Folientaster an der Mega2560 anschließen.
Es geht darum, dass ich mehrere Seiten von Messwerten einfach mit dem Druckknopf wechseln will in der Reihenfolge z. B. Seite1--drucken--Seite2--drucken---Seite3--drucken-- Seite1 usw..
Das Problem ist, ich weiß gar nicht, wie ich das Beispiel text in mehrere Screens aufteilen soll und nachher mit dem Knopf umschalten.
In dem Beispiel Sketch ist 3-mal Hallo in verschiedenen Farben, leider aber nur auf einer screen.

Zeichne mall wie ist der "Druckknopf" verbunden, ist ein Widerstand zu GND? Wie in dem Beispiel? https://funduino.de/nr-5-taster-am-arduino
Mach anders verbinde den Taster mit GND, und im setup `
Der "Druckknopf" ist verbunden mit 1K Widerstand zu GND. Der Sketch habe, ich geändert aber ich glaube, dass es gar nicht funktioniert. Der Code ist bestimmt falsch. Leider kann ich kein passendes Beispiel im Netz finden.
