How to Build W6300-EVB-Pico or W6300-EVB-Pico2 on Arduino

This guide provides instructions on how to build the W6300-EVB-Pico or W6300-EVB-Pico2 on Arduino. The Arduino version used is 1.8.19, which can be downloaded from the link below.

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 4.6.0 or later).
   
    
2. Build example and check
   Go to File -> Examples -> lwIP_w6300 -> WiFiClient-W6300
   And Go to Tools -> Board -> Raspberry Pi RP2040 -> WIZnet W6300-EVB-Pico or WIZnet W6300-EVB-Pico2
   
   
   
    
3. Click Upload
   
   
   Check serial terminal
   Since the WiFi module is not currently connected, an error will occur, but you can check that an IP address is assigned to the Ethernet through DHCP.
   
    

In this library, the W6300 operates via QSPI.
The QSPI pins are defined by default in the following path:
