基于C8051F410的128*64带字库点阵LCD显示器设计 摘要：LED（Light Emitting Diode）行业已成为一个快速发展的新兴产业，市场空间巨大，前景广阔。本文介绍了基于单片机的LED显示屏设计。其中着重介绍了LED点阵显示的硬件设计思路、硬件电路各个部分的功能及原理、相应软件的程序设计，以及详细的使用说明和工作流程。 本文分为六部分，其中主要内容是系统总体分析,系统硬件设计系统软件设计三部分。系统总体分析是基础；系统硬件设计是本文的关键及核心部分，该部分首先简单描述系统硬件工作原理，且附以系统硬件设计框图，论述了本次毕业设计所应用的各硬件接口技术和各个接口模块的功能及工作过程；软件设计是系统运行必不可少部分。 关键词：C8051F410 LED 点阵 汉字 Based on the C8051F410 128*64 character dot-matrix LCD display design Louyunfeng (Wenzhou School of Physics and Electronic and Information Engineering, 10 Electrical Engineering and Automation) Abstract This design in view of the present LED display monitor, in national dividends many domains obtain in the widespread quotation situation, has carried on this paper design after the investigation. This article elaborated in detail with monolithic integrated circuit development LED lattice demonstration in aspect and so on advertisement, propaganda applications, introduced the LED lattice demonstration hardware design mentality, hardware circuit each part of functions and the principle, the corresponding softwares programming emphatically, as well as detailed operating instructions and work flow. This design divides into six parts, the primary coverage is the system macro analysis, the system hardware design, the system software designs three parts. The system macro analysis is this article foundation, the system hardware design is this article key, is this design hard core, this part first simply describes the system hardware principle of work, and attaches by the system hardware design diagram, elaborated various hardware interface technology which and each interface module function and the work process this graduation project applies. The system software design is this article sublimation. this article composes the guiding ideology is the software and hardware unifies, take the hardware as the foundation, carries on various functional module the design.
