AT89S52 Mini Development Board – Interfacing μRFID (EM-18 Compatible)

The AT89S52 Mini Development Board provides on board support for interfacing RFID reader. Radio-frequency identification (RFID) technology enables remote and automated gathering and sending of information between RFID tags or transponders and readers using a wireless link. Using RFID the exchange of data between tags and readers is rapid, automatic and does not require direct contact or line of sight. The RFID module can be interfaced with the board using the same serial reception program used for testing the UART. When a Card (tag) is brought near the RFID reader, it tries to communicate with the tag, receives the data and decodes it. Finally it send the data over the Tx line. The UART module in MCU receives the data and thus used for further applications. The sample code below describes interfacing of UART and RFID module and thus displays the data over the LCD.
