A Python interface for using the RC522 SPI RFID module with NTAG21x tags on Raspberry Pi.
Note: for a general-purpose RPi RC522 library, refer to pi-rc522. In comparison, this project:
- Focuses on NTAG21x and does not support other tags (not even the MIFARE Classic series).
- Provides high-level wrappers for the main NTAG21x functionality: reading/writing data, authenticating, configuring password protection.
- Has a polling-based interface, does not use the
IRQpin. - Replaces return codes with exceptions, which not only make the code quite a bit cleaner, but also allow errors to have informative messages.
- Works with (and was actually developed for) MFRC522 clones with the
0x12version code. Unlike the original chips, they don't support soft reset, so the code performs a hard reset on initialization instead. - Uses a pigpio-based C implementation, which means it's slightly faster, but requires root to run.
The project is not available on PyPI at the moment. You can install it system-wide on RPi with the following commands:
git clone https://github.com/timlathy/rc522pi
cd rc522pi
python3 setup.py installCheck out the usage example to see the module in action.
