2. Anyone got this thing working? (2.13in e-ink display) : esp8266

   Works with GxEPD library using GxGDEW0213Z16 display type.
   Not GxEPD2 :-(

5. To everyone having issues · Issue #11 · HelTecAutomation/e-ink · GitHub

   By now you know this repository is crap. This is what worked for me on a 1.54 e-ink display. It should work on other sizes as well.
   
   NOTE: This display requires 3.3 data lines. It works on 5v data lines, but just barely. The display is not crisp. I've read it's possible to use a 10k/4k7 resistor divider for 5v data lines, but it didn't work for me.
   
   Download this library https://github.com/ZinggJM/GxEPD
   
   From Arduino IDE, open the example
   
   Select this display
   #include <GxGDEH0154D67/GxGDEH0154D67.h> // 1.54" b/w
   
   Use these pins
   GxIO_Class io(SPI, /CS=/ 10, /DC=/ 9, /RST=/ 8);
   GxEPD_Class display(io, /RST=/ 8, /BUSY=/ 7);
   
   Connect as follows (display / arduino):
   VCC / VCC
   GND / GND
   D/C / D9
   SDI / D11
   CS / D10
   CLK / D13
   BUSY / D7
