Raspberry Pi Pico W's LED doesn't blink #12

Closed ilgrandeanonimo closed 4 days ago

ilgrandeanonimo commented 1 month ago

Today I tried to run the Blinky example on my Raspberry Pico Pi W. I sucefully builded the .uf2 file:

but when i install the .uf2 file the led doesn't blink

Build Output:

phausler commented 2 weeks ago

The pico-w does not have a GPIO pin enabled for the LED; instead it uses the wireless chip to extend the GPIOs - this would require some additional HAL code to interact with that chip.

phausler commented 2 weeks ago

You can use the https://github.com/apple/swift-embedded-examples/tree/main/pico-w-blink-sdk example to do that instead. That one is built to use the existing pico sdk and interface for the pico-w

I think @phausler's solution is correct, please reopen this issue with more details if the solution does not work for you.
