Adapted from the Adafruit graphicstest sketch.
|
|
|
|
This sketch uses the GLCD font (font 1) only. Disable other fonts to make
|
|
the sketch fit in an UNO!
|
|
|
|
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.
