This sketch demonstrates the Adafruit graphicstest sketch running in a
|
|
viewport (aka window) within the TFT screen area. To do this line 37 has
|
|
been added. Line 39 draws a frame outside the viewport.
|
|
|
|
This sketch uses the GLCD font (font 1) only.
|
|
|
|
Make sure all the display driver and pin connections are correct by
|
|
editing the User_Setup.h file in the TFT_eSPI library folder.
