      4  This sketch uses the GLCD font (font 1) only. Disable other fonts to make
      5  the sketch fit in an UNO!
      6 
      7  Make sure all the display driver and pin connections are correct by
      8  editing the User_Setup.h file in the TFT_eSPI library folder.
      9 
     10  Note that yield() or delay(0) must be called in long duration for/while
     11  loops to stop the ESP8266 watchdog triggering.
