🚀 WIZnet-ioNIC-micropython-examples

• Main firmware repository:
  • https://github.com/WIZnet-ioNIC/WIZnet-EVB-Pico-micropython.git
• This repository contains MicroPython example scripts for the WIZnet EVB Boards.

⚡ Quick Start (Release UF2 Recommended)

Step 1: Download Firmware

• Download the appropriate firmware.uf2 file for your board from the Releases page.
  • Example: build-W55RP20_EVB_PICO/firmware.uf2, build-W6300_EVB_PICO/firmware.uf2

Step 2: Flash Firmware

1. Hold down the board's BOOTSEL button and connect via USB
2. The RPI-RP2 drive will automatically mount
3. Drag & drop the downloaded firmware.uf2 file into the RPI-RP2 drive
4. The board will automatically reboot after the copy is complete

💡 If you built from source, use ports/rp2/build-<BOARD>/firmware.uf2 with the same procedure.

🛠️ Example Scripts

This repository includes various network example scripts:

• Loopback.py : TCP server/client example
• dhcp.py : DHCP-based example
• HTTP_Client.py : HTTP/HTTPS request examples
• dns_client.py : DNS domain name resolution example
• sntp.py : NTP time synchronization example
• redis_client.py : Redis server connection and data store/retrieve example

Edit the configuration (network, board name, etc.) at the top of each script to match your environment, then run with Thonny or similar tools.

🧪 Verify Operation (REPL)

After the board reboots, connect to the serial port REPL and test with the following example:

from wiznet_init import wiznet
nic = wiznet("W55RP20-EVB-Pico", dhcp=True)
print('ifconfig:', nic.ifconfig())

🔧 Upload Scripts with Thonny (Optional)

1. In Thonny, set the interpreter to MicroPython (Raspberry Pi Pico)
2. After connecting to REPL, upload your example scripts to the board for execution
