1、成都理工大学工程技术学院毕业论文IC卡读写器的单片机实现作者姓名:专业名称:指导教师:讲师IC卡读写器的单片机实现摘要随着电子技术行业的快速发展,人们生活的水平也提高了很多,IC卡慢慢的在人们生活中就被广泛的使用了。IC卡不仅将便捷了人们的生活,人们的消费方式也因为IC卡而发生了改变。换一种方式来说,就是IC卡的出现改写了人类传统的现金支付方式,从而实现了轻便式生活方式。从而开启了快捷支付新时代。本文讲述了一种基于51单片机,使用MFRC522IC卡识别芯片的IC卡读卡器的设计过程和原理。该读卡器是包括上位机与单片机之间的数据交换和控制和单片机与IC卡之间的数据交换过程,具有成
2、本低,稳定性好,设计比较简单等优势,适用于大面积的市场各领域的运用。在目前生活中,IC卡在现代社会中有着相当大的作用,对于我们学习和理解单片机的使用,是一种难得的实践机会,为以后的正式进入后社会奠定基础。设计不仅具有实用价值,更重要的是能够实践和经验积累的内在意义。关键词:读写器非接触单片机IC卡89C51-42-IC卡读写器的单片机实现AbstractWiththerapiddevelopmentofelectronictechnology,people'slivingstandardscontinuetoimprove,theICcardhasbeenwidelyusedi
