pyFirmata gives error: module 'inspect' has no attribute 'getargspec'

Question

I'm trying to use pyFirmata, but I can't get it to work. Even the most basic of the library does not work. I guess there is something wrong with the library code.

from pyfirmata import Arduino,util
import time

port = 'COM5'
board = Arduino(port)

I get this error:

Traceback (most recent call last):
  File "c:\Users\Public\pythonpublic\arduino.py", line 5, in <module>
    board = Arduino(port)
            ^^^^^^^^^^^^^

AttributeError: module 'inspect' has no attribute 'getargspec'. Did you mean: 'getargs'?

Answer 1

According to the first line of pyFirmata docs:

It runs on Python 2.7, 3.6 and 3.7

You are using Python 3.11. The inspect (core library module) has changed since Python 3.7.
