Image RFID (EB052, RWD_MICODE) component

Low level routines for controlling a RF Solutions RFID interface Allows communications between Mifare, ICode and HiTag type RFID tags. Also available in the form of the EB052 RFID E-block.

Examples

Reading the status

The status of the RFID module is read using the "GetRFIDStatus" macro which returns a byte which is then displayed using the PORTB pins. FC6 Icon.png RFID Status Status byte breakdown for Mifare.

Reading and Writing Data

Example which talks to a ICode type card and allows the data to be read and written via a keypad. FC6 Icon.png RFID Read/Write

Macro compatibility

Not all the macros can be used with all card types, here is a list of RFID transponder types and the macros that are compatible.

GetRFIDTypeID

Collects the 3 bytes required to determine which kind of MIFARE device is present. Stores the result into the local buffer 0 - 2 and returns the response of the module.

Parameters

This macro has no parameters


Return value

BYTE


WriteRFIDBlock

Writes a block of information to the RFID device.

Parameters

BYTE Address
Remote RFID Block Address.
BYTE Key_Type


Return value

BYTE


WriteRFIDModule

Stores a byte of data to the internal EEPROM of the RFID module at the address specified.

Parameters

BYTE Address
BYTE Data


Return value

BYTE


DecrementRFIDValue

Perfoms a 32-bit decrement on the number held in location page or block.

Parameters

BYTE Src
Page / Block
BYTE Dst
Page / Block
BYTE Key_Type
Needed for MIFARE Commands


Return value

BYTE


FormatRFIDValue

Initialises the internal buffer of the Microcontroller so that it is ready to perform a Increment, Decrement or Transfer command.

Parameters

This macro has no parameters

Return value

BYTE


TransferRFIDValue

Perfoms a 32-bit block data transfer on the number held in location page or block.

Parameters

BYTE Src
Page / Block
BYTE Dst
Page / Block

Needed for MIFARE Commands


Return value

BYTE


GetRFIDUID

Collects the UID from a RFID device. Stores the result into the UID buffer and returns the response of the module.

Parameters
