Pico W WiFi + LED
Overview
This sample demonstrates concurrent WiFi and LED operation on the Raspberry Pi Pico W and Pico 2 W. A background thread blinks the onboard LED via the CYW43 GPIO driver while the main thread performs a WiFi scan.
Requirements
This sample requires a board with an Infineon CYW43439 WiFi chip:
Raspberry Pi Pico W (
