Join your Wi-Fi
Pico W and Pico 2 W use the saved Wi-Fi network. Pico, Pico 2, and Waveshare RP2040-Matrix have no Wi-Fi and display NO IP; use USB to upload.
The board discovers its own Wi-Fi address when it starts and scrolls it across the selected display. If the board is offline, it shows “NO IP”.
How it works
The board reads its network address and keeps it moving across the LED display.
