在没有设备的情况下为 Raspberry Pi Pico W 编写 MicroPython 代码

Question

I have ordered a Raspberry Pi Pico W which hasn't arrived yet. Is there a way for me to start writing MicroPython code before the Pico is here?

I tried Thonny as suggested in the Raspberry Pi Documentation and set it to use the "MicroPython (Raspberry Pi Pico)" interpreter:

But that sems to require an actual device, as Thonny keeps saying

Device is busy or does not respond. Your options:
- wait until it completes current work;
- use Ctrl+C to interrupt current work;
- reset the device and try again;
- check connection properties;
- make sure the device has suitable MicroPython / CircuitPython / firmware;
- make sure the device is not in bootloader mode.

Well, of course I can set Thonny to use the "Local Python 3" interpreter instead, but I guess that could result in code which does not necessarily run on a Pi Pico then?

Update

The Pico is here now and I can say that online emulators such as Wokwi do not (fully?) work:

import machine
led = machine.Pin("LED", machine.Pin.OUT)
led.on()

lead to

Traceback (most recent call last):t str to int
MicroPython v1.19.1 on 2022-06-18; Raspberry Pi Pi
File "main.py", line 3, in <module>
TypeError: can't converco with RP2040

Maybe a different version of Micropython? Wifi is not available as well, which obviously is a bummer for the Pico W .

Answer 1

OK, kind of embarrassing: While being focussed on Thonny and how to set it up, I missed online emulators. There's ie Wokwi which looks promising. If there's a drawback and/or I find a better one, I'll update this answer.

Answer 2

There are some results searching for virtual Raspberry Pi Pico for example raspberry-pi-pico-emulator-keypad-and-led-interface-project .

I'm not sure how customizable it is for your own projects, but worth a look.
