Pin as string doesn't work

[jumperwire]

Hello,

I have Raspberry Pi Pico W with:

Code: Select all

Python version
3.4.0; MicroPython v1.19.1 on 2022-06-18
Version info.
(3, 4, 0)

When I am trying to run the following:

Code: Select all

from machine import Pin

led = Pin( "LED", Pin.OUT )
led.on()
led.off()

I get an error:

Code: Select all

Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
TypeError: can't convert str to int

I can't specify integer value for the LED, because on Pico W it's not pin 25 any more. I have no idea what integer number is the LED on. But everywhere in the google I see people are using string values as well as in documentation it says as id I can use string.
Any idea?

You need to be using the latest unstable version for that to work
