RP2040 and ESP32 code example

1】 Download the decompression package

2】 Code for burning ESP32

2.1] Turn the dial switch to ESP32, RT and TX to RP2040

      

2.2] In the extracted package, enter the RP2040andESP32 folder, and then enter RP2040 again_ ESP32 folder, open RP2040_ ESP32.ino

Install the ESPAsyncWebSrv third-party library

(Note: Each person's path is different)

    

Copy the path to my computer path search box


After entering librariesh, locate the ESPAsyncWebSrv folder and enter,


Then enter src and open the AsyncWebSocket.cpp file


Modify the I PAddress AsyncWebSocketClient:: remoteIP() in it

Before modification


After modification


2.3] Configure Arduino IDE_ ESP32C3 parameter


After configuring the parameters as shown in the above figure, enter the WIFI name and password

2.4] After burning, open the serial port monitor


After burning, open the serial port monitor


At the beginning, there will be a connection process, and after a moment, you can see the STA IP address (the WIFI address is different for everyone). Copy to website


After copying the IP address to the website, the following figure appears
