Design And Realization Of RF IC Card Reader System Based On MSP430 Microcontroller

This paper mainly introduces RF IC card reader subsystem of the device that can stored the information of GPS and photo in IC card, details of the RF IC card reader important role in the terminal, and describes in detail based on MSP430F2274 chip RF IC card reader system for the design and implementation process. Specifically, the paper introduces the Features of the RF IC card, the international standards and the reasons for Selecting IC. In theory RF IC card reader systems and communication mechanisms, the paper describes the working principle, characteristics of the RF interface, data transfer mechanisms and communication. In practice, the paper introduces detail the RF IC card reader hardware design and software implementation. On the hardware, the MCU of the system is MSP430F2274 MCU and the RF IC chip if TRF7960. On the software, the paper highlights the software programming ideas and anti-collision programming ideas.
