I’m trying to use a mfrc522 mifare reader on a Rpi 3b as per tutorial here and have downloaded the mfrc522 library and installed python3-dev and spidev.

When I try to import the mfrc522 library in a simple python script, the interpreter can’t find the “machine” module used in the mfrc522.py library.

import RPi.GPIO as GPIO
from mfrc522 import SimpleMFRC522

reader = SimpleMFRC522()

try:
        id, text = reader.read()
        print(id)
        print(text)

finally:
        GPIO.cleanup()

Traceback (most recent call last):
  File "read_tag.py", line 4, in <module>
    from mfrc522 import SimpleMFRC522
  File "/home/pi/python/raspberrypi_mfrc522/mfrc522.py", line 1, in <module>
    from machine import Pin, SPI
ModuleNotFoundError: No module named 'machine'

I can’t find what library package this module should exist in.. Can anyone help me try to figure out what libraries I need to (re)install to get this working??

Thanks in advance!

Thanks
