基于单片机的LED点阵图文显示控制VIP免费

四川理工学院毕业设计（论文）基于单片机的LED显示系统控制设计学生：张波学号：06021050225专业：电子信息科学与技术班级：2006.2指导教师：黄晓莉四川理工学院自动化与电子信息系二零一零年六月摘要由于单片机技术的不断发展和高亮度LED发光管的出现使得大屏幕高亮度LED电子广告屏成为可能，与传统的霓虹灯广告在显示效果以及可修改性上都有着无法比拟的优势，而且单片机的日益平民化以及LED技术的不断创新，使得高亮度高清晰的LED点阵广告牌与传统霓虹灯广告牌的成本日益接近。另外，SMT技术的飞速发展，开关电源的大规模使用，使其无论在体积上还是在可靠性上都比传统的霓虹灯广告有明显的优势，为其在特殊领域的应用奠定了基础。为了能简单的实现基于单片机的LED显示系统控制，我们将设计一个室内用32*64点阵LED单色图文显示屏，它能在目测条件下LED显示屏各点亮度均匀，充足，可显示图形和文字，显示图形或文字稳定、清晰无串扰；图形或文字显示有静止和移入移出等显示方式。(摘要是论文内容的简要陈述，是一篇具有独立性和完整性的短文。摘要应包括本设计（论文）的成果及其理论与实际意义。摘要中不宜使用公式、图表，不标注引用文献编号。避免将摘要写成目录式的内容介绍。设计（论文）摘要不超过300字。)关键词：单片机；LED显示屏点阵；网络；套接字（关键词：4－8个）(关键词是供检索用的主题词条，应采用能覆盖论文主要内容的通用技术词条（参照相应的技术术语标准）。中文摘要在前，对应的英文摘要在后另页书写。)注：专科学生不写英文摘要和文献综述。ABSTRACTTexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttexttextKeywords:Distributedsystem；Event-driven；Network；Socket目录ABSTRACT...........................................................II第1章引言........................................................11.1标题..................................................................................................................................11.1.1标题.........................................................................................................................11.2标题..................................................................................................................................1第2章设计任务及要求...............................................22.1设计题目..........................................................................................................................22.1.1标题.........................................................................................................................22.2设计要求与目的...............................................................................................................2实现LED点阵屏核心功能即汉字、数字、字母的多样化显示；......................................22.3设计任务..........................................................................................................................2设计系统硬件；...............................................2设计系统软件；...............................................2编写设计说明书。......
