// Display Library example for SPI e-paper panels from Dalian Good Display and boards from Waveshare.
// Requires HW SPI and Adafruit_GFX. Caution: the e-paper panels require 3.3V supply AND data lines!
//
// Display Library based on Demo Example from Good Display: https://www.good-display.com/companyfile/32/
//
// Author: Jean-Marc Zingg
//
// Version: see library.properties
//
// Library: https://github.com/ZinggJM/GxEPD2
//
// Purpose: show uses of GxEPD2_GFX base class for references to a display instance
//
// BitmapDisplay shows the use of the display instance reference as a class member

// but here display.epd2.panel is not known at compile time.
