毕 业 设 计指导老师：2025 年 5 月 24 日课题名称基于单片机的 LED 点阵图文显示控制设计院/专 业 机械工程学院/ 机电一体化班 级 学 号学生姓名摘要LED 的点阵图文显示目前被广泛应用于各个方面，尤其当 LED 点阵图文显示与功能强大且价格低廉的单片机，其化学效应异常剧烈，单片机不仅丰富了 LED 点阵图文显示的应用范围，也增强了其有用性。本次毕业设计就是针对 STC89C52 单片机作为驱动 LED 的图文显示控制的芯片，主要阐述了单片机的硬件结构，工作原理及方式，LED 的工作方式及原理以及相关软件的运行。讨论了单片机对 LED 点阵显示屏的控制技术。在以上理论为基础的前提下，我设计了搭建基于单片机的 LED 图文点阵图文显示控制的电路，并用相关的元器件，在万用电路板上以焊接的形式，实现了单片机对 LED 点阵显示屏的图文控制，并最终达到预期设计要求。关键词：LED；单片机； 点阵控制 ABSTRACTLED lattice of graphic display has been widely applied in various aspects, especially when the LED dot-matrix graphic display and powerful and low cost of single chip microcomputer, the chemical effect unusually intense, single-chip microcomputer not only enriched the application range of the LED lattice graphic display, also enhanced its usefulness. This graduation design is aimed at the STC89C52 single-chip microcomputer as the drive LED graphic display control chip, mainly expounds the hardware structure of single chip microcomputer, working principle and mode, working way and principle of the LED and the operation of relevant software.Studies the technique of single-chip microcomputer control of the LED dot matrix display screen. On the premise of theory on the basis of above, I designed the building graphic dot-matrix LED graphic display based on MCU control circuit, and related components in universal circuit boards in the form of welding, implements the single-chip microcomputer control of LED dot matrix display screen shots, and ulti...
