花样流水灯毕业设计

摘要

近年来随着科技的飞速发展，单片机的应用正在不断地走向深入，同时带动传统控制检测日新月异更新。在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用，仅单片机方面知识是不够的，还应根据具体硬件结构，以及针对具体应用对象特点的软件结合，加以完善。

正文首先介绍本课题的背景、研究意义及完成的任务功能；接着简单描述设计过程中所用的一些主要元器件、方案的论证，以及介绍了系统硬件工作原理，并且附以系统硬件设计框图；其次阐述了ＰＣＢ板的画质、制作、实物的完成、程序的编写和调试；最后对本设计进行了总结。

本次毕业设计根据设计要求，基本达到预期的目的。即通过ATmega16单片机来控制16x8的贴片发光二极管矩阵显示，以中、明字符为例，分别可以实现‘全亮’到字模‘中’再到字模‘明’到‘全暗’的循环显示。用户可以按照自己的喜好选择不同的字模、显示方式。关键词：单片机 ATmega16 发光二极管霓虹灯

Abstract

In recent years, with the rapid development of science and technology, SCM applications are continually deepening, while the traditional control test drive rapid updates. In real-time detection and control of the microcomputer application system, the microcontroller is often used as a core component, Jin Zhi Shi MCU side is not enough, Haiyinggenju specific hardware structure and application specific characteristics of the software Duixiang Jie He, to be perfect.

The text introduces the subject of this issue background, significance, and complete functionality. A brief description of the design process used in some of the major components of the demonstration program, and introduced the principle of the system hardware, and attached to the system hardware design block diagram; second section describes the PCB board of the definition, production, physical completion of the preparation process and debugging; Finally, a summary of the design.

The graduation project according to set requirements, achieves the desired purpose. ATmega16 microcontroller to control through the SMD LEDs 16x8 matrix display to the Ming character, for example, were able to achieve 'full light' to the font 'in' then font 'out' to 'all dark' cycle of ers can follow their own preferences to select a different font, display

Keywords: microcontroller ATmega16 LBD Neon
