// Display Library 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!

//
|
|
// based on Demo Example from Good Display: https://www.good-display.com/product/426.html

// Panel: GDEQ031T10 : https://www.good-display.com/product/426.html
