IC card will not only facilitate people's lives, but also to promote the transformation of people's consumption patterns. In a sense, the emergence of the IC card to rewrite the traditional way of cash payment, opened a new era of fast payment. In the current society in twenty-first Century, the IC card reader has become very common, such as in the bank, consumer office also can be seen everywhere. Even our campus life with campus card, in supermarkets, schools the school cafeteria and red card center are IC read write device to recharge. This design is on the IC card read write principle and design methods of research and analysis.At the same time, the IC card has become an integral part of most people's life, it is referred to as the integrated circuit identification card. This paper introduces a based on 89C52 microcontroller series and to MF522 is a highly integrated contactless card reader chip as the core of the IC card read write device, and introduces the implementation of IC card data storage methods and ideas. The IC card reader can access the data, delete data, IC card data and modify the data processing, so as to realize the recharge and consumption function. At the same time, the reader can connect the computer, through the relevant data in computer operation, through the microcontroller to drive the corresponding MF522 IC card chip operation to modify the data in the card. In addition, also can be directly used directly in the input control device is connected only single-chip microcontroller development or input and display equipment directly based on the corresponding operation.IC 卡读写器的单片机实现-III-The author believes that the contemporary society active in the IC card, learning and understanding of SCM application development, is a rare practice experience. Especially for graduating students, understand the principle of the IC card identification and based on single chip microcomputer, the design of hardware and software, will be able to further study and master the development process of the microcontroller similar platforms and development train of thought and method, for the later formally entered the post design to lay the foundation. The design not only has practical value, but more important is the ability and experience accumulation in the inner meaning.Keywords: Card reader,no contact ,IC card,SCM,89C51IC 卡读写器的单片机实现-IV-目录目录摘要.IAbstract.II目录.IV前言.61 IC 卡读写器简单介绍.71.1 IC 卡的简单介绍.7 1.2 51 单片机的简单介绍.8 1.3 MFRC522 芯片介绍 .9 1.4 IC 卡读写器系统介绍.102 硬件设计.122.1 IC 卡读写器硬件开发环境介绍.12 2.2 硬件设计平台的搭建.13 2.3 硬件设计原理和思路分析.163 软件设计.193.1 软件开发平台介绍.19 3.2 软件设计思路分析.20 3.3 程序设计与分析.21 3.3.1 程序流程图.213.3.2 程序分析.234 IC 卡读写器的使用演示.274.1 软件安装.27 4.2 软件使用方法介绍.30 4.3 效果展示.
