基于RFID的读卡器模块设计

摘要

RFID reader system which is based station chip MRC531 and M3S9B90 chip based on Cortex-M3 reads and writes MifarelS50 card. The system is realized with a frequency of 13. 56MHz MifarelS50 card identification data read and write, and the same time, it can also be convenient with the host computer to communicate. Communication uses open source TCP / IP protocol stack LWIP.%以MFRC531为基站芯片,以Mifare1S50卡为读写对象,以基于Cortex-M3的LM3S9B90芯片为控制器构建基于RFID的读卡器系统.该系统实现了对采用频率为13.56MHz的Mifare1S50卡的识别与数据读写,同时该系统还可以方便地与上位机进行通信.通信采用开源的TCP/IP协议栈LWIP.
