ESP32/2.13" 250x122 3-color Epaper Module using ZinggJM/GxEPD2

Display on 2.13" 250x122 3-color E-paper (SSD1680) with ESP32-DevKitC V4 using ZinggJM/GxEPD2 Library (in arduino-esp32 framework).

Visit WeAct Studio 2.13/2.9 Inch Epaper Module EPD in GitHub (https://github.com/WeActStudio/WeActStudio.EpaperModule). It provide info and example code for WeAct Epaper Modules. We are going to use EpaperModuleTest_Arduino_ESP32 Example later, it use GxEPD2 library to control e-paper.

Visit Github ZinggJM/GxEPD2 (https://github.com/ZinggJM/GxEPD2). To download library in ZIP:
Click on Code > Download ZIP

Open Arduino IDE, to install download library:
Sketch > Include Library > Add ZIP Library
Select the downloaded ZIP file

Connection

To run the examples below, we follow the connection in WeAct Example:

e-paper	ESP32 GPIO
------------------
1 BUSY	GP15
2 RES	GP2
3 D/C	GP0
4 CS	GP5
5 SCL	GP18
6 SDA	GP23
7 GND	GND
8 VCC	3V3

Try WeAct Example

Then copy WeAct Example, EpaperModuleTest_Arduino_ESP32.

For 3-color 2.13'' EPD Module 122x250 SSD1680, use:

GxEPD2_3C<GxEPD2_213_Z98c, GxEPD2_213_Z98c::HEIGHT> display(GxEPD2_213_Z98c(/*CS=5*/ 5, /*DC=*/ 0, /*RST=*/ 2, /*BUSY=*/ 15)); // GDEY0213Z98 122x250, SSD1680

Try example from GxEPD2 library

In Arduino IDE
Open Examples > GxEPD2 > GxEPD2_Example

Edit GxEPD2_display_selection.h to define display following EpaperModuleTest_Arduino_ESP32 example.

updated@2023-03-30:

GxEPD2 is available in Arduino Library List now, that means you can install it in Arduino IDE's Library Manager directly.
