Constructors

MfRc522(I2cDevice, Int32, GpioController, Boolean)	Constructor for MFRC5222 with I2C interface.
MfRc522(SerialPort, Int32, GpioController, Boolean)	Constructor for MFRC5222 with Serial Port interface.
MfRc522(SpiDevice, Int32, GpioController, Boolean)	Constructor for MFRC5222 with SPI interface.
MfRc522(String, Int32, GpioController, Boolean)	Constructor for MFRC5222 with Serial Port interface.

Fields

DefaultSpiMode	Only SPI Mode supported is Mode0
MaximumSpiClockFrequency	The maximum speed for SPI transfer speed
SupportedProtocols	The set of NFC protocols that are supported by this transceiver.

Properties

Enabled	Switch on or off the antenna.
Gain	Get or Set the gain.
MaximumReadSize	The maximum number of bytes that can be read from the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver).
MaximumReadSize	The maximum number of bytes that can be read from the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver). (Inherited from CardTransceiver)
MaximumWriteSize	The maximum number of bytes that can be written to the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver).
MaximumWriteSize	The maximum number of bytes that can be written to the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver). (Inherited from CardTransceiver)
SerialSpeed	Set or Get the baud rate for the serial port communication. Default is 9600 baud.
Version	Get the Version.

Methods

Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Halt()	Stop to communicate with a card.
IsCardPresent(Byte[], Boolean)	Check if a new card is present.
IsCardPresent(Byte[])	Check if a new card is present.
ListenToCardIso14443TypeA(Data106kbpsTypeA, TimeSpan)	Listen to any 14443 Type A card.
MifareAuthenticate(ReadOnlySpan<Byte>, MifareCardCommand, Byte, ReadOnlySpan<Byte>)	Specific function to authenticate Mifare cards
PrepareForSleep()	Prepare for sleep, make sure cryptography is off and switch off the antenna.
ReselectTarget(Byte)	Once you have an authentication operation failing with Mifare cards or a read/write, the card stop. TYhe only way to have it back is to send the unselect and anti collision. This function provides this feature
SendAndReceiveData(MfrcCommand, ReadOnlySpan<Byte>, Span<Byte>, Byte)	Sand and Receive Data.
SoftReset()	Perform a soft reset. The configuration data of the internal buffer remains unchanged.All registers are set to the reset values.This command automatically terminates when finished.
Transceive(Byte, ReadOnlySpan<Byte>, Span<Byte>, NfcProtocol)	This function has to be implemented by all NFC/RFID/Card readers. This function is used in exchange of data with the reader and the cards.
Transceive(Byte, ReadOnlySpan<Byte>, Span<Byte>, NfcProtocol)	This function has to be implemented by all NFC/RFID/Card readers. This function is used in exchange of data with the reader and the cards. (Inherited from CardTransceiver)
Transceive(Byte, ReadOnlySpan<Byte>, Span<Byte>)	This function has to be implemented by all NFC/RFID/Card readers. This function is used in exchange of data with the reader and the cards.
Transceive(Byte, ReadOnlySpan<Byte>, Span<Byte>)	This function has to be implemented by all NFC/RFID/Card readers. This function is used in exchange of data with the reader and the cards. (Inherited from CardTransceiver)
