JoyIT_RC522

A python library to read/write RFID tags via the MFRC522 RFID module.

This code was edited for the use with Raspberry Pi 5 by Joy-IT. Therefore the 'RPi.GPIO' library was exchanged with 'gpiozero'.The source code was published in relation to a blog post and you can find out more about how to hook up your MFRC reader to a Raspberry Pi there.

Prerequirements:

SPI has to be enabled, otherwise a error message will be shown ("FileNotFoundError: [Errno 2] No such file or directory").

To enable SPI you can do the following:

1. sudo raspi-config
2. Interface Options -> SPI -> Enable

Installation

This library is for the use with virtual environments for the Raspberry Pi 5 and older models.

mkdir your_project
cd your_project
python -m venv --system-site-packages env
source env/bin/activate

pip3 install spidev
pip install JoyIT-RC522

Example

In this library are two example codes. One is for reading from a tag and the other is for writing on a tag. You can execute them like the following.

git clone https://github.com/joy-it/MFRC522-python
python3 MFRC522-python/examples/write.py
python3 MFRC522-python/examples/read.py
