英文摘要: Abstract :LED electronic display screens, which are applied more and more widely,have been generally accepted by the whole society as an important propagandistic platform,In this work,a digital 16*32 dot matrix LED electronic display screens was designed and made from a 8x8LED electronic display screen and the related peripheral circuits ,with a microcontroller as the controlling core. The thesis introduces the design of a dot matrix display based on AT89C51 the design ideas of 16*32 dot matrix LED display,and expounding the realization process of system hardware and software design in thesis focuses on the design ideas and making of modularization of display module and related driving design including interrupt module and display module is also the idea of modularization,and it comes true by the application of a simple and popular language can achieve the function of a clear graphic with Happy Valley with moving-out and moving-in the actual design and debugging process,they observe the stability of the pictures on the scream through eyes,and find if they are clear without any interference,and work out the reasons why the pictures are not clear,then adjust the plan and make the pictures match to the requirements as mach as possible. Key words: AT89C51 Micro Controller Unit; LED; Lattice display; Dynamic display; Assembly language. 指导教师评语: 指导教师签名: 年 月 曰 编号: 时间:x月x曰 书山有路勤为径,学海无涯苦作舟 页码:
