    II便捷式单片机实验开发装置[摘要] 《单片机基础》 、 《微机原理与应用》课程对许多专业来说是非常重要的专业基础课。目前,我国各高校大多是以MCS-51单片机(简称51系列)或者 8086CPU(简称86系列)为主要内容进行教学。尤其是近年来,随着半导体技术与计算机技术的飞速发展,大量高性能、采用新技术的嵌入式系统CPU的面世,让电子技术再次飞跃新的台阶。在高校单片机课程逐步成为电子专业的一门重要的专业基础课,所以在教学过程中采用理论知识的学习和实践操作相结合的方式,以便于初学者更好地在理解的基础上掌握这门技术。论文首先叙述了课题背景,根据教学需要,进行模块化组合式设计的基本方案和思路。其次,讲述了51及AVR系列单片机的基本特性。通过对关键的设计电路的分析,说明了51及AVR单片机综合实验系统相应设计模块的实验目的和意义。最后,对课题进行了总结,说明在开发该装置的实际意义。[关键词] 单片机;PCB;ISP 在线下载;USB 下载IIISCM development of portable test equipment[ABSTRACT] “SCM basis“, “Principles and Computer Application“ Curriculum for many professional is very important basis of the professional classes. At present, China's universities and colleges are mostly MCS-51 SCM (51) or 8086 CPU (referred to 86 series) as the main content of teaching. Especially in recent years, As semiconductor technology and the rapid development of computer technology, A large number of high-performance, Introduction of new technology embedded systems the CPU available, Electronics once again leap to new heights.SCM courses in colleges and universities will gradually become a professional e-important foundation for the professional classes, So in the process of teaching a theoretical knowledge of the study and practice of combining operations, Beginners in order to better understand the master on the basis of this gate technology.Papers described the first subject background,According to teaching needs,The modular design of a modular programme and the basic line of thought.Secondly, on 51 and AVR microcontroller series of the fundamental characteristics. Through the key to the design of the circuit analysis shows that 51 and AVR microcontroller integrated experimental system corresponding design of the experimental module purpose and significance.Finally, the subject of the summary, Help in the development of the practical significance of the device.[Key word] SCM;PCB;ISP online download; USB downloadIV目录0 引言 -----------------------------------------------------------------------------------------------11 课题背景 -----------------------------------------------------------------------------------------21.1 单片机概述 ------------------------------------------------------------------------------21.2 单片机课程教学现状 ------------------------------------------------------------------21.3 课题的研究意义 ------------------------------------------------------------------------32 系统组成结构概述 -----------------------------------------------------------------------------42.1 系统的组成 ------------------------------------------------------------------------------42.2 实验内容 ---------------------------------------------------------------------------------42.3 系统框图 ---------------------------------------------------------------------------------53 硬件电路设计 -----------------------------------------------------------------------------------63.1 8051 系列单片机—— AT89S52 -------------------------------------------------------63.1.1 引脚功能 ----------------------------------------------------------------------------83.1.2 串口通信 ---------------------------------------------------------------------------103.1.3 串口通信方式 ---------------------------------------------------------------------103.1.4 串行通信控制寄存器 ------------------------------------------------------------103.1.5 数据发送与接收 ------------------------------------------------------------------113.2 单片机最小系统 -----------------------------------------------------------------------123.3 ISP 在线下载模块 ---------------------------------------------------------------------133.4 USB 下载模块 ---------------------------------------------------------------------------143.5 串口通信模块 --------------------------------------------------------------------------143.6 4*4 键盘模块 ---------------------------------------------------------------------------153.7 LM386 低频功放及 1302 时钟模块 -------------------------------------------------163.8 数码管显示模块 -----------------------------------------------------------------------163.9 液晶接口及 24C02 存储模块 --------------------------------------------------------174 系统开发软件环境 ---------------------------------------------------------------------------18V4.1 开发软件的使用说明 -----------------------------------------------------------------184.2 WAVE6000 的使用 -------------------------------------------------------------------184.3 下载软件—— 双龙 MCU 下载器的使用 -----------------------------------------204.4 progist1.67 下载软件的用 -----------------------------------------------------------215 实验指导书设计与编写 ---------------------------------------------------------------------225.1 数制转换与单片机端口的控制 -----------------------------------------------------225.2 4*4 键盘应用 ---------------------------------------------------------------------------245.3 串行通信 --------------------------------------------------------------------------------255.4 计数器定时器的应用 -----------------------------------------------------------------265.5 1602 液晶显示 -------------------------------------------------------------------------295.6 单片机音乐播放器制作 --------------------------------------------------------------30结论 --------------------------------------------------------------------------------------------------32致谢语 -----------------------------------------------------------------------------------------------33参考文献 --------------------------------------------------------------------------------------------34附录一 系统原理图 -----------------------------------------------------------------------------35附录二 实验程序 --------------------------------------------------------------------------------36附录三 英文原文 --------------------------------------------------------------------------------47附录四 英文译文 --------------------------------------------------------------------------------54附录五 数据光盘 --------------------------------------------------------------------------------60
