-
-    @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)

-    Version: November 12, 2010

-

-  This library is designed to use CC1101/CC1100 module on Arduino platform.

-  CC1101/CC1100 module is an useful wireless module.Using the functions of the 

-  library, you can easily send and receive data by the CC1101/CC1100 module. 

-  Just have fun!

-  For the details, please refer to the datasheet of CC1100/CC1101.

-    Version: November 12, 2010

-

-  This library is designed to use CC1101/CC1100 module on Arduino platform.

-  CC1101/CC1100 module is an useful wireless module.Using the functions of the 

-  library, you can easily send and receive data by the CC1101/CC1100 module. 

-  Just have fun!

-  For the details, please refer to the datasheet of CC1100/CC1101.
