摘要
介绍一种基于EM4094模拟前端芯片和LPC2132高性能MCU的多协议RFID读卡器系统设计。通过对多个现有13.56MHz的通用RFID协议、目前流行的防冲撞算法以及模拟前端的研究,得到合理的软件流程设计,并最后给出最终设计效果。
The design of a multi-protocol RFID reader system based on the analog front-end EM4094 and a high-performance MCU LPC2132 are introduced. After the research on the existing RFID protocol on 13.56 MHz and anti-collision algorithm, a reasonable software process is found out, and the last results of the system is provided.
