Members description:

Initialize (CSPin As Byte, ResetPin As Byte, CardPresentSub As SubVoidArrayByte) As void

Initializes the object.
CSPin - Chip Select pin (also called SS).
ResetPin - Reset pin.
CardPresentSub - Sub that will handle the CardPresent event.

MifareAuthenticate2 (BlockAddress As Byte, Key() As Byte, KeyA As Boolean) As Boolean

Gains access to the specified block.
BlockAddress - Block index.
Key - Array of 6 bytes.
KeyA - If true then key A will be used. Otherwise key B will be used.

MifareRead (BlockAddress As Byte, Buffer() As Byte) As Byte

Reads the data from the specified block. Returns the number of bytes read.
You should first call MifareAuthenticate.
BlockAddress - Block index.
Buffer - Data will be written to this buffer. Must be 18 bytes or more.
The last two bytes are the checksum.

MifareWrite (BlockAddress As Byte, Buffer() As Byte) As Boolean

Writes data to the specified block. Returns true if writing was successful.
You should first call MifareAuthenticate.
BlockAddress - Block index.
Buffer - Data to write. 16 bytes will be written (array length must be 16 or more).

TYPE_ISO_14443_4 As Byte

PICC compliant with ISO/IEC 14443-4

TYPE_ISO_18092 As Byte

PICC compliant with ISO/IEC 18092 (NFC)

TYPE_MIFARE_1K As Byte

TYPE_MIFARE_PLUS As Byte

MIFARE Plus

TYPE_MIFARE_UL As Byte

MIFARE Ultralight or Ultralight C

TYPE_NOT_COMPLETE As Byte

TYPE_TNP3XXX As Byte

Only mentioned in NXP AN 10833 MIFARE Type Identification Procedure

TYPE_UNKNOWN As Byte
