Problem Importing Simple Function From "LibraryFolder" To "Main"

[Eloufou]

Just realized its in the wrong section. im using RP2040 tho

I want to create a simple code to test if I am able to import a library with some function from the "LibraryFolder.py" to the "main.py" but it does not work. I checked in several GitHub Forum but can't find anything...

here is the "main.py"

from LibraryFolder import blink_led

# Call the function to start blinking the LED
blink_led()

and here is the "LibraryFolder.py"

from machine import Pin
from utime import sleep

def blink_led():
    pin = Pin("LED", Pin.OUT)
    print("LED starts flashing...")
    while True:
        try:
            pin.toggle()
            sleep(1) # sleep 1sec
        except KeyboardInterrupt:
            break
    pin.off()
    print("Finished.")

and here is the Error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: no module named 'LibraryFolder'

Im coding in VSCode V1.87.2 with Python V3.12.2

Thanks for your help!

os.listdir() will list your files. Are both of your files present where you expect them to be?

sys.path will show what the import path is. Is the directory where those files are on the path?

As an alternative, use mpremote with it's mount feature, which mounts directories on the PC as local directories on the board.

ill try this

I need to put the .U2F file in the RP2040? If so, do I need to take the one for the 2 codes and where do I find them?

You have to copy the Python files to the board. The .uf2 file is only uploaded by the bootloader during firmware update. With the bootlaoder you cannot upload Python files.
A tool to upload python Files is for instance mpremote. If you work with Thonny (it seems to be the case), then you may as well use Thonny for that task. But I highly reccomend mpremote, since that is the official tool for MicroPython.

For mpremote, see https://docs.micropython.org/en/latest/reference/mpremote.html
