HISTORY

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 uint8_t * data, const uint32_t numuint8_ts) static void PrintHexChar(const uint8_t * pbtData, const uint32_t numuint8_ts)
• 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)
