A small class to interface with the NFC reader Module MFRC522 on the Raspberry Pi.
This is a Python port of the example code for the NFC module RF522-AN.
- Install on Raspberry Pi running Jessie
- Install on Raspberry Pi running Wheezy
- Usage
- Useful Resources
- Disclaimer
Make sure you have the latest kernel (>= 4.4.14), because it fixes a bug in earlier version Issue #1547.
You can check your version using:
uname -a | sed -E "s/.*([0-9]+\.[0-9]+\.[0-9]+)-v.*/\1/"
If you need to update your kernel, use sudo rpi-update. If it's not yet installed, do so using sudo apt-get install rpi-update.
| RF522 Module | Raspberry Pi |
|---|---|
| SDA | Pin 24 / GPIO8 (CE0) |
| SCK | Pin 23 / GPIO11 (SCKL) |
| MOSI | Pin 19 / GPIO10 (MOSI) |
| MISO | Pin 21 / GPIO9 (MISO) |
| IRQ | – |
| GND | GND |
| RST | Pin 22 / GPIO25 |
| 3.3V | 3.3V |
sudo raspi-config
And then go to 9 – Advanced Options > A5 SPI and enable the SPI interface.
Reboot (sudo shutdown -r now).
You can verify a successful configuration by entering
ls /dev/spi*
The output should be similar to the following, thus confirming the existence of the necessary sockets.
/dev/spidev0.0 /dev/spidev0.1
Make sure you have Python and Git installed:
sudo apt-get install git python3-dev --yes
git clone https://github.com/mab5vot9us9a/SPI-Py && cd SPI-Py
sudo python3 setup.py install
cd ..
git clone https://github.com/mab5vot9us9a/MFRC522-python.git && cd MFRC522-python
python3 Dump.py
and place your tag (MIFARE Classic 1K (S50)) on the reader to dump its data.
Follow these instructions: RASPBERRY PI RFID RC522 TAGS AUSLESEN (NFC).
Import the class by importing MFRC522 in the top of your script. For more info see the examples.
