Temperatur auf Display ausgeben läuft - fast

[DH4MBM]

Problem solved!
Herzlichen Dank für eure Hilfe.
Aus dem setup() habe ich die Befehlszeile :

tft.setTextColor(TFT_BLUE); // TFT_WHITE = Black - TFT_BLUE = White

entfernt. Das hat die Farben durcheinander gewürfelt. Weißer Hintergrund mit schwarzer Schrift funktioniert.

Ich nutze dieses Display: https://eckstein-shop.de/Mega-2560-3...d-fuer-Arduino
Es liest zwei Dallas-DS18B20 Temperatursensoren aus. http://playground.arduino.cc/Learning/OneWire
Auf beiden Seiten findet ihr die zugehörige library.

Hier nun der funktionierende Code:

   

/*
  
  Test the tft.print() viz the libraries embedded write() function
  Make sure all the required fonts are loaded by editting the
  User_Setup.h file in the TFT_ILI9341 library folder.
