16×16点阵LED显示屏整个过程及C语言程序(1).
16×16点阵LED显示屏整个过程及C语言程序7.1功能要求设计一个室内用16×16点阵LED图文显示屏，要求在目测条件下LED显示屏各点亮度均匀、充足，可显示图形和文字，显示图形或文字应稳定、清晰无串扰。
图形或文字显示有静止、移入移出等显示方式。
7.2方案论证从理论上说，不论显示图形还是文字，只要控制与组成这些图形或文字的各个点所在位置相对应的LED器件发光，就可以得到我们想要的显示结果，这种同时控制各个发光点亮灭的方法称为静态驱动显示方式。
16×16的点阵共有256个发光二极管，显然单片机没有这么多端口，如果我们采用锁存器来扩展端口，按8位的锁存器来计算，16×16的点阵需要256/8=32个锁存器。
这个数字很庞大，因为我们仅仅是16×16的点阵，在实际应用中的显示屏往往要大的多，这样在锁存器上花的成本将是一个很庞大的数字。
因此在实际应用中的显示屏几乎都不采用这种设计，而采用另一种称为动态扫描的显示方法。
动态扫描的意思简单地说就是逐行轮流点亮，这样扫描驱动电路就可以实现多行（比如16行）的同名列共用一套列驱动器。
具体就16×16的点阵来说，我们把所有同一行的发光管的阳极连在一起，把所有同一列的发光管的阴极连在一起（共阳的接法），先送出对应第一行发光管亮灭的数据并锁存，然后选通第一行使其燃亮一定的时间，然后熄灭；再送出第二行的数据并锁存，然后选通第二行使其燃亮相同的时间，然后熄灭；……第十六行之后又重新燃亮第一行，这样反复轮回。
当这样轮回的速度足够快（每秒24次以上），由于人眼的视觉暂留现象，我们就能看到显示屏上稳定的图形了。
采用扫描方式进行显示时，每行有一个行驱动器，各行的同名列共用一个列驱动器。
显示数据通常存储在单片机的存储器中，按8位一个字节的形式顺序排放。
显示时要把一行中各列的数据都传送到相应的列驱动器上去，这就存在一个显示数据传输的问题。

16乘16点阵显示实验报告
实验报告实验名称： [16×16点阵显示实验] 姓名： []学号： [2011]指导教师： []实验时间： [2013年4月25日]信息与通信工程学院16×16点阵显示实验1实验要求任务1：将所给程序改正使结果为正显示；任务2：使显示四个字、八个字。
2实验原理2.1 LED显示器结构和原理1>8*8LED点阵的结构图1 8*8LED点阵结构图从图1中可以看出，8*8LED点阵共由64个发光二极管组成，每个发光二极管是放置在行线和列线的交叉点上，当对应的某一行置1高电平，且某一列置0低电平，则相应的发光二极管就亮；因此要用8*8LED点阵来显示一个字符或汉字，只需要根据字符或汉字图形中的线条或笔画，通过点亮多个发光二极管来勾勒出字符或汉字的线条或笔画就行了。
当要比较完美的显示一般的汉字，单个8*8LED点阵模块很难做到，因为LED的点数（也称为像素点）不够多，因此要显示汉字的话，需要多个8*8LED点阵拼合成一个显示屏。
假如用4个8*8LED点阵模块拼成16*16的点阵，即能满足一般汉字的显示。
但要显示信息量大的图形，则需要n个多个8*8LED点阵，拼装成一个大屏幕才行。
LED点阵显示器最大的特点是亮度高、功耗较低、寿命长、容易控制等，因此它的应用很广，常用在广场、车站、商业广告等室外的显示。
2>8*8LED点阵的封装和引脚规律64个发光二极管按照行共阳、列共阴4个一组的方式封装成一个模块，这样8*8LED 点阵模块就有8行、8列共16个引脚。
其实物图如图2，电路模块符号图如图3。
图2 8*8LED点阵实物图图3 8*8LED点阵符号图但8*8LED点阵的16个引脚并不是很有规律，千万不要想象成1~8个引脚是行，9~16个引脚是列。
而且不同产品的点阵外部引脚排列规律还可能不一样。
以下是NLB1388SRA 和LDM1388SRA两个型号点阵引脚对应行、列的关系表：行号H0 H1 H2 H3 H4 H5 H6 H7引脚号9 14 8 12 1 7 2 5列号L0 L1 L2 L3 L4 L5 L6 L7引脚号13 3 4 10 6 11 15 16 假如你买到一块新的8*8LED点阵，又没有关于它的相关资料，那你只有自己用万用表或通过VCC电源串接一个510欧姆的电阻来检测了。

LED点阵显示屏可以显示数字或符号, 通常用来显示时间、速度、系统状态等。
文章给出了一种基于MCS-51单片机的16×16 点阵LED显示屏的设计方案。
包括系统具体的硬件设计方案,软件流程图和部分汇编语言程序等方面。
在负载范围内, 只需通过简单的级联就可以对显示屏进行扩展,是一种成本低廉的图文显示方案。
关键词：MCS-51；LED；单片机AbstractAs a popular display device component, LED dot-matrix display board consists of several independent LED (Light Emitting Diode). The LED dot-matrix display board can display the number or sign, and it is usually used to show time, speed, the state of system etc. This paper introduces a kind of simple 16ｘ16 LED display screen design process based on MCS-51 single chip minicomputer . The detail hardware scheme, software flow and assemble language programmer design and so on is followed. The display part can be cascaded to meet the need. The practice proves the design is low-cost and effective.Key words: MCS-51；LED；MCU1设计原理1.1 MCS-51单片机的结构及编程方法MCS-51单片机的组成： CPU(进行运算、控制)、RAM(数据存储器)、ROM(程序存储器）、I/O口(串口、并口）、内部总线和中断系统等。

LED16×16点阵汉字显示设计(VHDL版)
毕业设计（论文）开题报告设计（论文）题基于FPGA的LED 16×16点阵汉字显示设计目一、选题的背景和意义：LED点阵显示屏是集微电子技术、计算机技术、信息处理技术于一体的大型显示屏系统。
它以其色彩鲜艳，动态范围广，亮度高，寿命长，工作稳定可靠等优点而成为众多显示媒体以及户外作业显示的理想选择。
受到体育场馆用LED显示屏需求快速增长的带动，近年来，中国 LED显示屏应用逐步增多。
目前，LED已经广泛应用在银行、火车站、广告、体育场馆之中。
而随着奥运会、世博会的临近，LED显示屏将广泛的应用在体育场馆以及道路交通指示中，LED显示屏在体育广场中的应用将出现快速增长。
因此，本设计是很有必要的，之所以基于FPGA设计是因为现场可编程门阵列（FPGA）设计周期小，灵活度高，适合用于小批量系统，提高系统的可靠性和集成度。
并且采用编写灵活的VHDL语言编写主程序。
本设计可以方便的应用到各类广告宣传中。

16×16点阵LED显示汉字
以下程序在16×16点阵LED上依次显示“梅川酷子”四个字，分别用正向显示和反向显示，间隔两秒钟变换一次，电路图和效果图下图所示。
AT89 c52晶振频率为24MHz，用T0定时，改变变量flag值，从而让程序确定显示哪个汉字和显示方式（正向or反向）。

16X16显示“汉字”
这是我玩LED点阵屏的第一块电路板，也是学习单片机入门的第一个实验器材。
它由4片30mm×30mm的8×8红色高亮点阵模块与两片74HC595、两片74HC138、16只8550晶体管、一片74HC244集装在一块宽高65mm×210mm的双面PCB板上，它应该是一组级联安装的LED屏的一个单元模块，拿到它时，我正在学习《无线电》杂志2007/11期刊上杜洋的一组文章，刚刚做好了ISP下载线，只做了“一个发光二极管的控制实验”，面对这个既好玩又陌生的玩意，真是无从下手，通过上网学习，解析研究，前后弄了两个多月，最后在《无线电》杂志2005/12期的配文程序的帮助下，终于踏进了点阵控制的门槛，两年过去了，我又玩了许多单片机控制器件，但这块屏却一直摆在我的桌案上，每当遇到难题时，看看它那稳定清晰的显示，我都能找到许多灵感；最近、在摆弄一块并行驱动的16×64点阵屏时（前几篇文章介绍了）时，因为用的还是这段程序，就又想起了它，虽然程序已经详解过了，但是，为了留记一段经历、一段回忆，决定还是“貂续狗尾”写在这里，留着自己欣赏吧。

16X16点阵显示实验
实验报告实验名称： [16X16点阵显示实验]姓名：学号：指导教师：实验时间： [2013年6月15日]信息与通信工程学院16X16点阵显示实验1、实验要求：理解并掌握点阵显示符号的原理，理解原有程序，会使用动态扫描的方式使点阵显示汉字，明白点阵滚动显示的原理。
根据原有程序，掌握LPM_ROM的应用，会应用LPM_ROM存储需要显示的内容。
参照液晶显示程序，编写16*16点阵显示程序。
任务一：实现点阵列扫描。
点亮点阵的一列，并让其不断的向右移动。
任务二：在点阵上循环滚动显示“嵌入式系统设计”。
2、实验原理：2.1点阵基本原理本实验对点阵的扫描使用列扫描的方式。
就是将要显示的数据分成16列，在某一时刻只选中一列，并向点阵传送该列需要显示的数据，那么如果从左往右依次循环选中所有列，并且循环的速度足够快，因为视觉停留效应，我们就能看到完整的显示了。
如果要显示大于16列的信息，比如要显示多个汉字，由于只能同时显示16列，那么就需要在一个比较慢的时钟的指挥下，不断更新要显示的连续的16列数据，使用这样的方法就能实现滚动显示。
2.2任务原理8*8LED点阵共由64个发光二极管组成，每个发光二极管放置在行线和列线的交叉点上，当对应的某一行高电平（置1），且某一列低电平（置0），则相应的发光二极管就亮；因此要用8*8LED点阵来显示一个字符或汉字，只需要根据字符或汉字图形中的线条或笔画，通过点亮多个发光二极管来勾勒出字符或汉字的线条或笔画就行了。
当要比较完美的显示一般的汉字，单个8*8LED点阵模块很难做到，因为LED的点数（也称为像素点）不够多，因此要显示汉字的话，需要多个8*8LED点阵拼合成一个显示屏。
假如用4个8*8LED点阵模块拼成16*16的点阵，即能满足一般汉字的显示。
16×16扫描LED点阵的工作原理同8位扫描数码管类似。
它有16个共阴极输出端口,每个共阴极对应有16个LED显示灯，所以其扫描译码地址需4位信号线（SEL0-SEL3），其汉字扫描码由16位段地址（0-15）输入。
