This is a library for the Adafruit PN532 NFC/RFID breakout boards This library works with the Adafruit NFC breakout
Check out the links above for our tutorials and wiring diagrams These chips use I2C or SPI to communicate.
Contributions are welcome! Please read our Code of Conduct before contributing to help this project stay welcoming.
Documentation is produced by doxygen. Contributions should include documentation for any new code added.
Some examples of how to use doxygen can be found in these guide pages:

This library uses clang-format to standardize the formatting of .cpp and .h files.
Contributions should be formatted using clang-format:
The -i flag will make the changes to the file.
clang-format -i *.cpp *.hIf you prefer to make the changes yourself, running clang-format without the -i flag will print out a formatted version of the file. You can save this to a file and diff it against the original to see the changes.
Note that the formatting output by clang-format is what the automated formatting checker will expect. Any diffs from this formatting will result in a failed build until they are addressed. Using the -i flag is highly recommended.
- Binary builds and source available on the LLVM downloads page
- Documentation and IDE integration Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
