Adapted from the Adafruit and Xark's PDQ graphicstest sketch.

This sketch uses the GLCD font only.

|
|
|
Make sure all the display driver and pin comnenctions are correct by
|
|
editting the User_Setup.h file in the TFT_eSPI library folder.
|
|
|
|
Note that yield() or delay(0) must be called in long duration for/while
|
|
loops to stop the ESP8266 watchdog triggering.
