LED 点阵显示屏系统设计( 一) 工学部工学一部专业自动化班级 B641301 学号 B64130132 姓名张琪指导教师应文博负责教师应文博沈阳航空航天大学北方科技学院 20 10年6月沈阳航空航天大学北方科技学院毕业设计(论文) I 摘要本设计利用 Visual Basic 编程语言编写 LED 点阵显示屏的上位机软件,并设计上位机与主控板上通信单片机的通信电路, 使用户能够通过此上位机软件对 LED 显示屏的显示内容及显示效果进行修改和设置。另外, 通信单片机还能与主控单片机相互配合, 对时钟芯片和温度传感器进行操作, 完成时间和温度信息的实时采集。本上位机软件能与 LED 点阵显示屏系统进行良好的通信, 易于实现显示效果的变换和显示内容的修改,并且拥有友好的人机对话界面,通用性好,操作简单、方便,具有较广阔的应用前景。关键词: LED 显示屏; Visual Basic ;上位机;通信沈阳航空航天大学北方科技学院毕业设计(论文) II Abstract This piles puter software for the LED dot matrix display monitor by using Visual Basic which isa kind of visual programming languages ,and designs munication circuit between the puter software and munication MCU on the master control board ,user can change the demonstrates content s and the demonstration effect sof the LED dot matrix display monitor. In addition, the coordination between the Main Control MCU and munication MCU, to update the time data and the temperature information real-time gathering. The puter software can carry on the good correspondence with the LED dot matrix display monitor system,and can change the demonstrates content s and the demonstration effect sof the LED dot matrix display monitor easily, t his puter software has the good man-machine contact surface,the good versatility,the simple and convenience operationality,and the broad application prospect.
