==Setup Arduino IDE (Winodws)==
To use the ESP32 board with Arduino IDE, you need to first add the support of the board package to the IDE. We use Windows PC as an example.<br />
The ESP32 used here is the Waveshare [https://www.waveshare.com/e-paper-esp32-driver-board.htm ESP32 e-Paper Driver Board]<br />
*Download the Arduino IDE from [https://www.arduino.cc/en/software/ Arduino website]
*Install the Arduino-ESP32 Support Page:[https://codeload.github.com/espressif/arduino-esp32/zip/master Click to download]
*Unzip the support package to the hardware/espressif/esp32 folder, which is under the installation directory of Arduino IDE. You may need to create them if you didn't find the directory on your PC.

*Enter the tools folder, run the get.exe file as administrator.
*After installing, restart the Arduino IDE, and you can find the ESP DEV Module options in the Tools-Boards menu of IDE

Download Demo Codes

The demo codes are included in the examples folder.

  • You should copy the esp32-waveshare-epd folder to the \hardware\espressif\esp32\libraries folder which is under the installation directory of IDE. The esp32-waveshare-epd is saved under the examples directory.
  • Epd esp32 example 1.png

Hardware connection

  • Raw panel + ESP32 Driver Board
If you have the ESP32 e-Paper Driver board as well as an e-Paper raw panel.You can just connect the e-paper panel to the ESP32 board as below:

Trigger state e-Paper
A 1.54inch e-Paper, 2.13inch e-Paper, 2.13inch e-Paper (D), 2.9inch e-Paper
B 1.54inch e-Paper (B), 1.54inch e-Paper (C)

2.13inch e-Paper (B), 2.13inch e-Paper (C)
2.7inch e-Paper (B)
2.9inch e-Paper (C), 2.9inch e-Paper (B)
4.2inch e-Paper (B), 4.2inch e-Paper (C)
5.83inch e-Paper (B), 5.83inch e-Paper (C)
7.5inch e-Paper (B), 7.5inch e-Paper (C), 7.5inch HD e-Paper, 7.5inch HD e-Paper (B)

Note: The ACeP e-Paper doesn't support this connecting method.

  • e-Paper Module/HAT + ESP32 Board
If you have the ESP32 Board as well as the e-Paper module/HAT which has PCB already, you can wire the displays by 8-pin cable pin
Connect to ESP32 Driver Board
e-Paper ESP32
Vcc 3.3V

Run the Demo Codes

  • Open the Arduino IDE
  • Choose File->Examples-> waveshae-e-Paper -> And the project according to the type of display
Epd esp32 example 2.png
  • Build and program the ESP32 board
  • Open the serial monitor, you can check the degbug information when runing the demo codes
