Create Default Class Function

create_default_Arduino_DataBus()

Arduino_GFX try to find the settings depends on selected board in Arduino IDE, if you selected a dev device that have built-in display the Arduino_GFX can be auto created:

#include <Arduino_GFX_Library.h>
Arduino_DataBus *bus = create_default_Arduino_DataBus();

If the dev board is not yet recognised, a Arduino_ILI9341 class is created.

create_default_Arduino_DataBus()

If your dev board does no built-in display, Arduino_GFX can still use default pin mapping to create a default Arduino_DataBus class for the display:
