USB mass storage mode

If you press the reset button while pressing the BOOT button, it will enter USB mass storage mode (RPI-RP2).

When in USB mass storage mode, you can install MicroPython or CircuitPython firmware from your PC.

Please refer to the following articles for how to install MicroPython and CircuitPython firmware.

You can use the firmware of Raspberry Pi Pico.

Add board to Arduino
IDE

Add Raspberry Pi Pico/RP2040 board ( earlephilhower version ) in advance.
See the article below for how to add.

Arduino Additional Boards (Third Party Boards) & Libraries Summary

I put together a list of boards (third-party boards) that require URLs to be added to Arduino and libraries that are often used. How to add a board Arduino IDE Open the > screen from the Arduino IDE. ...

Installing the Raspberry Pi Pico/RP2040 board

Install the Raspberry Pi Pico/RP2040 board by clicking Tools > Boards > Board Manager and entering 'rp2040' in the search box.

board selection

Select [Tool] > [Board] > [Raspberry Pi RP2040 Boards(Ver)] > [WIZnet WizFi360-EVB-Pico].

Serial port selection

Select the serial port to which WizFi360-EVB-Pico is connected from [Tools] > [Serial Port].

If you have an environment that cannot write from a serial port, such as a Chromebook, you can write sketches manually.

How to write Arduino sketch to Raspberry Pi Pico/RP2040 board without using serial communication

In some environments such as Chromebook (Linux development environment = Crostini) and Raspberry Pi OS, it is not possible to write sketches to RP2040-equipped boards (such as Raspberry Pi Pico) via serial communication.

Install WizFi360 library

download

The library for WizFi360-EVB-Pico is below (GitHub).

https://github.com/Wiznet/WizFi360_arduino_library/tree/WizFi360-EVB-Pico

Download the ZIP file from Code > Download ZIP .

install

Arduino IDE

Sketch > Include Library > Install .ZIP Library…

Click.

Select the downloaded ZIP file to install.

Sample program (Arduino sketch)

Sketch example

Arduino IDE File > Example Sketch > Try some WizFi360 sketches.

Connect WPA

Open the example sketch ConnectWPA .

Replace the following (Wi-Fi information) with the Wi-Fi information of the connection destination and write the sketch.

/* Wi-Fi info */
char ssid[] = "wiznet";       // your network SSID (name)
char pass[] = "0123456789";   // your network password

You can check the information of the connected Wi-Fi from the serial monitor.

Web Server AP

Sketch example Open WebServerAP and write a sketch.

WizFi360-EVB-Pico is WebServer, so try to connect.

Connection example with a smartphone (iPhone)

Tap wiznet from Wi-Fi.

Enter "0123456789" for the password and tap "Connect".

If you open the wiznet information (tap the i mark), you can see that the IP address (router) is "192.168.36.1".

When you access http://192.168.36.1 from your browser , the following is displayed.

Browser Chrome usage example

Also, the serial monitor of the Arduino IDE is displayed as follows.
