摘要
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Mi-fare1S50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。
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 host computer to communicate. Communication uses open source TCP / IP protocol convenient with the stack LWIP.
