Blink onboard LED on Pico W using PIO?

[mdaeron]

Sorry if this is obvious, but I can't seem to find a way to blink the Pico W's onboard LED using the PIO.

rp2.StateMachine(0, blink, freq=2000, set_base=machine.Pin('LED')) yields the following error: ValueError: expecting a regular GPIO Pin.

Is there an obvious workaround that I'm missing?

This is not possible to do on the Pico W, because on that board the built-in LED is driven by the WiFi chip (the CYW4343). So there's quite a lot going on to turn that LED on/off, it's not a simple GPIO on the RP2040.

Thanks! I assumed (wrongly) that the simplest way to tech myself to write a PIO program was to blink that LED. No worries.
