==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==
*Download the ESP32 Demo codes [https://www.waveshare.com/w/upload/5/50/E-Paper_ESP32_Driver_Board_Code.7z e-Paper ESP32 Driver Codes] to your PC.
*Unzip the demo codes
: The demo codes are included in the examples folder.
:[[File:Epd esp32 download 1.png|500px]]
*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.

==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:

'''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

==Run the Demo Codes==
*Open the Arduino IDE
*Choose File->Examples-> waveshae-e-Paper -> And the project according to the type of display
:[[File:Epd esp32 example 2.png|700px]]
*Build and program the ESP32 board
*Open the serial monitor, you can check the degbug information when runing the demo codes
