1、.基于单片机的IC卡读写器设计摘要：随着社会的进步和现代化程度的不断提高，人类所拥有的信息种类和数量都在成倍地增长，每天都要处理许多与个人有关的信息，而这些信息管理十分不便。因此，在实际生活中IC卡的应用范围非常广泛，它有助于解决问题。IC卡读写器是IC卡和计算机之间的传输媒介，它与计算机之间通过串行口相连，本文主要应用89C2051单片机为核心对SLE4442卡进行读写控制。接触式IC卡是IC卡领域的一项新兴技术,它是射频识别技术和IC卡技术相结合的产物。首先在绪论中介绍了课题的开发意义及功能概述。其次在主要描述了系统硬件工作原理，并介绍了I
2、C卡SLE4442的内部结构及原理图，论述了本次毕业设计所应用的各硬件接口技术和各个接口模块的功能及工作过程。本系统是以单片机的基本语言汇编语言来进行软件设计，指令的执行速度快。最后具体描述了各个功能模块的软、硬件调试。本文撰写的主导思想是软、硬件结合，以硬件为基础，来进行各功能模块的编写。关键词：读写控制，单片机，IC卡。Abstract:Raisecontinuouslyalongwiththeprogressandmoderndegreeofthesociety,theinformationcategoryandquantitiestha
