1. Installing Raspberry Pi Pico/RP2040/RP2350 Boards
   Open Arduino, go to File -> Preferences -> Additional Boards Manager URLs:
   Input https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
   
   
   And go to Tools -> Board -> Boards Manager, search for 'RP2040', and install Raspberry Pi Pico/RP2040/RP2350 (version 4.2.0 or later).
   
    
2. Download W55RP20-Ethernet3 Library
   Clone or download it from the following W55RP20-Ethernet3 GitHub link (https://github.com/WIZnet-ioNIC/W55RP20-Ethernet3) into your Arduino libraries folder (e.g., Documents/Arduino/libraries), and then run DhcpAddressPrinter.ino from the examples folder.
    
3. Build example and check
   Go to Tools -> Board -> Raspberry Pi RP2040 -> WIZnet W55RP20-EVB-Pico
   
    
4. Upload
   Press and hold the BOOTSEL button on the board, then press the RUN button. After that, click the Upload button in Arduino to build the firmware, and verify it through the Serial Monitor
