微机课设实验报告.doc

课程设计(综合实验)报告( 2014 - 2015 年度第 一 学期)名称：微机原理及应用 题目：在液晶LCD上显示汉字字符图形院系：控制与计算机工程学院班级：自动1203学号：姓名：其他组员：指导教师：吴华 设计周数：1 成绩：日期：2015年1月11日课程设计（综合实验）报告一、 课程设计(综合实验)的目的与要求目的：了解单片机AT89C52和AMPIRE128X64汉字图形型液晶显示屏的应用，学会字模转换及在单片机仿真软件上测试程序。使我们掌握单片机的内部功能模块的应用，培养系统设计的思想。培养软件设计能力，提高动手能力。培养学生查阅相关资料、撰写文档的能力和自学、科研的能力。要求：a) 使用单片机和LCD，编程在LCD的中心显示汉字字符串“微机原理及应用课程设计”。 b) 编程从LCD中间的最右端开始，从右向左滚动显示汉字字符串“微机原理及应用课程设计”。 二、设计（实验）正文 （1）根据应用系统的要求，初步掌握总体结构的方法和构思，从中选择一种最佳的设计方案。 （2）根据应用系统结构规模的要求，掌握在单片机AT89C52外部扩展系统硬件设计的基本过程：例如接口的设计，正确合理选用所需元器件，在proteus上绘制LCD与单片机连接的电路图等项工作。 （3）通过点阵液晶取模软件获得汉字字符串的字模。 （4）根据设计任务和要求，首先画出程序总体流程图，然后进行各控制模块程序的设计、编写系统程序。 （5）掌握如何应用单片机仿真软件Keil C51来开发应用系统及仿真调试的过程。 （6）在proteus环境下用程序控制仿真电路，在LCD显示屏上得到所需的效果。三、课程设计（综合实验）总结或结论 在这次课设过程中，我们自学了单片机的编程与接口连线。出于对显示汉字的数目等因素的考虑，我们选择了AMPIRE128X64汉字图形型液晶显示屏，同时，我们自学了取模软件的应用以及下载了Keil C51来方便我们的编程。proteus环境有大量的库元件，从而使我们选择在其中仿真实验电路。四、参考文献 1 何立民.单片机应用技术选编M.北京航空航天大学出版社：2011.10. 2
