Install the ESP32 PLug-in in the Arduino IDE
1. Open the Arduino IDE, click on the file in the upper left corner, and select Preferences.
2. Add the following link in the additional development board manager URL, then click OK.
https://dl.espressif.com/dl/package_esp32_index.json
Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:
https://dl.espressif.com/dl/package_esp32_index.json, http://arduino.esp8266.com/stable/package_esp8266com_index.json
3. Download the packages, unzip the packages and copy the files to the following path:
C:\Users\xutong\AppData\Local\Arduino15
Note: Replace the username: xutong with your own username.
Software Download And Run
- Download the sample demo.
- Copy the files under
..\ESP32\librariesto the libraries under the Arduino IDE installation directory
(Arduino IDE 2.0 or above, the libraries path is general C:\Users\"your_user_name"\AppData\Local\Arduino15\libraries) - After connecting the wires according to the hardware connection diagram, the software settings are as follows:
- Open the demo through File, see the relative path:
