Waveshare 7.5" ePaper (B/W/R) and GxEPD porting

[Norfeldt]

The GxEPD2 has been generously ported by @ZinggJM - thank you so much!

GxEPD2_PP : Particle Display Library for SPI E-Paper Displays

GxEPD2_PP is the GxEPD2 Arduino Library ported to Particle Photon It supports SPI e-paper displays from Dalian Good Display and the display boards from Waveshare that use these display panels. This topic is intended for asking questions, reporting problems and issues, and hopefully telling your successful use of these displays. Support and information can also be found in the Arduino Forum Display topics: https://forum.arduino.cc/index.php?topic=487007.0 https://forum.arduino.cc/index.php?t…

(Now I need to figure out how to print my own images and not the logos in the lib)
