PN532 NFC HAT

This is a PN532 NFC library for Raspberry Pi.

Features

• Support I2C, SPI and HSU of PN532
• Easy to understand how the PN532 chip works

How to use

1. Plug the PN532 NFC Hat to your Pi.
2. The module supports I2C, SPI and HSU.

• on I2C:

  MOSI/SDA/TX Pin to Pi's SDA
  NSS/SCL/RX Pin to Pi's SCL
  

  Then set SEL0: ON and SEL1: OFF
• on SPI:

  MOSI/SDA/TX Pin to Pi's MOSI
  NSS/SCL/RX Pin to Pi's CE0
  

  Then set SEL0: OFF and SEL1: ON
• on HSU(UART):

  MOSI/SDA/TX Pin to Pi's RX
  NSS/SCL/RX Pin to Pi's TX
  

  Then set SEL0: OFF and SEL1: OFF

3. Run the example with python3 example.py
4. With waving a 13.56MHz NFC card, the UID of the card will be printed.
