基于单片机的LED广告信息展示屏控制电路设计

摘要

为了实现LED广告信息展示屏的控制，提出了一种基于单片机的LED广告信息展示屏控制设计方案，并完成系统的软硬件设计。该系统的硬件部分主要用单片机进行电路的控制，软件部分采用keil uvision4进行编程，能够完成广告信息的滚动播出或多幅信息的自动切换播放，同时也可手动切换并固定在一幅信息上。电路软硬件测试结果表明，设计方案正确可靠，检测的结果符合设计指标。%In order to realize the control of LED advertising information display screen, a LED advertising information display screen control design scheme based on MCU is proposed, and the hardware and software design of the system is completed. The hardware of the system mainly by single chip computer circuit control, part of the software using keil uvision4 programming, to complete the advertisement information broadcast of a rolling or more pieces of information automatically play, also can be manually switched and fixed on a piece of information. The results of the system show that the design scheme is correct and the results are in line with the design target.
