-// 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, available here: http://www.e-paper-display.com/download_detail/downloadsId=806.html
-// Panel: GDEH0154D67 : http://www.e-paper-display.com/products_detail/productId=455.html
-// Controller : SSD1681 : http://www.e-paper-display.com/download_detail/downloadsId=825.html
