+
+ @section intro_sec Introduction
+
+ Driver for NXP's PN532 NFC/13.56MHz RFID Transceiver
+
+ This is a library for the Adafruit PN532 NFC/RFID breakout boards
+ This library works with the Adafruit NFC breakout
+ ----> https://www.adafruit.com/products/364
+
+ Check out the links above for our tutorials and wiring diagrams
+ These chips use SPI or I2C to communicate.
+
+ Adafruit invests time and resources providing this open source code,
+ please support Adafruit and open-source hardware by purchasing
+ products from Adafruit!

+
+ @section HISTORY
+
+ v2.2 - Added startPassiveTargetIDDetection() to start card detection and
+ readDetectedPassiveTargetID() to read it, useful when using the
+ IRQ pin.
+
+ v2.1 - Added NTAG2xx helper functions
+
+ v2.0 - Refactored to add I2C support from Adafruit_NFCShield_I2C library.
+
+ v1.4 - Added setPassiveActivationRetries()
+
+ v1.2 - Added writeGPIO()
+ - Added readGPIO()
+
+ v1.1 - Changed readPassiveTargetID() to handle multiple UID sizes
+ - Added the following helper functions for text display
+ static void PrintHex(const byte * data, const uint32_t numBytes)
+ static void PrintHexChar(const byte * pbtData, const uint32_t
+ numBytes)
+ - Added the following Mifare Classic functions:
+ bool mifareclassic_IsFirstBlock (uint32_t uiBlock)
+ bool mifareclassic_IsTrailerBlock (uint32_t uiBlock)
+ uint8_t mifareclassic_AuthenticateBlock (uint8_t * uid, uint8_t
+ uidLen, uint32_t blockNumber, uint8_t keyNumber, uint8_t * keyData) uint8_t
+ mifareclassic_ReadDataBlock (uint8_t blockNumber, uint8_t * data) uint8_t
+ mifareclassic_WriteDataBlock (uint8_t blockNumber, uint8_t * data)
+ - Added the following Mifare Ultalight functions:
+ uint8_t mifareultralight_ReadPage (uint8_t page, uint8_t * buffer)
