Lopaka is a web-based tool for creating graphics and user interfaces for electronic projects, supporting various display types and libraries. It allows users to create images and interfaces visually, with generated source code for integration into projects.
Works with GxEPD library using GxGDEW0213Z16 display type.
Not GxEPD2 :-(

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
