系统由单片机、外围电路、单片机最小系统以及显示电路构成。

关键词:AT89C51单片机;LCD;Proteus中图分类号:TN702 文献标识码:A 文章编号:1674-7712 (2012) 12-0046-02一、引言亮丽实用的广告牌可以给我们的生活添加光彩、可以给店铺招揽生意。
传统的广告牌都是固定的汉字,并且时间长了会掉色,使汉字模糊难认,这给我们的生活带来很多的不便。
尤其是到了晚上传统的广告牌就失去了作用。
因此我们需要一种造价低廉、使用方便、可以发光、可以方便改变汉字且比较耐用的电子显示广告牌。
二、设计过程及工艺要求(一)基本功能1.可以发光;2.可以滚动;3.可以用电脑改变汉字。
(二)主要技术参数1.单片机选择AT89C51;2.LCD显示器选择SMG12864A或AMPIRE128×64;3.晶振选择12MHz;4.两个输出电容选择30pF;5.两个外围电阻选用10K和100Ω。
本设计的主要任务是显示标语,因此在硬件安装方面需要有适当的面积来安装电子显示屏,并且还要通过数据线把电子显示屏和电脑连起来。
三、系统的总体设计(一)系统设计本设计是基于51单片机的LCD汉字滚动显示,该设计是以AT89C51基本系统为核心的一套应用系统,其中包括单片机、复位电路、外围电路、显示电路、系统软件等部分的设计【1】。
(二)芯片AT89C51介绍AT89C51是一种带4K字节闪存可编程可擦除只读存储器(FPEROM—Flash Programmable and Erasable Read Only Memory)的低电压、高性能CMOS 8位微处理器, 该器件采用ATMEL高密度非易失存储器制造技术制造,与工业标准的MCS-51指令集和输出管脚相兼容。

【实验内容】1．编程要求：主程序利用C 语言编写，调用驱动程序。
2．实现功能：在LCD显示器上按行显示20个汉字，内容自拟。
3．实验现象：清屏，持续一段时间，显示第一行，持续一段时间，再显示第二行，依次循环显示每一行。
【实验原理】1. DM Tool 字模提取工具与显示英文字符（ASCII 码）不同，汉字不能直接显示在点阵的LCD显示器上，而是要借助一个工具，先把汉字转换成LCD 显示器能显示的形式。
可以利用unSP 系列16 位单片机的字模数据提取工具DM Tool提取汉字字模、BMP位图字模，还可以很方便地提取ASCII 码字模。
2. SPLC501 液晶显示模组汉字显示API 函数介绍驱动程序文件SPLC501User.c 同样定义了显示汉字的API 函数，在SPLC501User.h 文件里也对这些函数进行了申明。
void LCD501_Init(unsigned int InitialData) //初始化液晶显示void LCD501_ClrScreen(unsigned int Mode) //点亮屏幕或清屏void LCD501_SetPaintMode(unsigned int ModeCode) //设置图形显示模式unsigned int LCD501_GetPaintMode(void) //获取图形显示模式void LCD501_Bitmap(unsigned int x,unsigned int y,unsigned int *word) //显示汉字或者位图的字模数据前面四个函数在上一实验中已经有详细说明，这里只介绍最后一个函数：【API 格式】C：void LCD501_Bitmap(unsigned int x,unsigned int y,unsigned int *word)【功能说明】显示汉字或者位图的字模数据【参数】x 表示显示字符的起始列（0~128）y表示要显示的字模的起始行（0~64-y_whide）*word 表示要显示的汉字字模的数据首地址【返回值】无【备注】只显示用DM T ool 取字模软件所取的汉字字模数据；该函数可以在指定位置显示位图。
