单片机16×16点阵显示实验总结400字

单片机16×16点阵显示实验总结400字单片机16×16点阵显示实验总结这次实验我们使用单片机设计了16×16点阵显示器的驱动电路，并成功实现了在点阵上显示字符、数字和图案的功能。

下面是对本次实验的总结。

首先，我们按照实验手册的指示，采用逐行扫描的方式驱动16×16点阵显示器。

通过设置接口电路和引脚连接，将单片机与点阵电路相连，实现数据和控制信号的传输。

接着，我们编写了相应的程序代码，在单片机上进行编译和烧录，并使用示波器进行调试。

在调试过程中，我们发现了一些常见的问题，比如接口线连接错误、引脚配置错误等，及时解决这些问题，确保了实验的顺利进行。

接下来，我们开始编写点阵显示的控制程序。

通过对点阵每一个LED灯珠的亮灭状态进行控制，我们可以实现在点阵上显示不同的字符、数字和图案。

我们编写了一个字符库，其中包含了常用字符和数字的点阵码。

通过查表的方式，我们可以根据需要在点阵上显示相应的内容。

在编写程序的过程中，我们充分利用了单片机的IO口和定时器的功能，并采用了合理的算法，提高了程序的执行效率。

在实验过程中，我们遇到了一些困难和挑战。

首先，点阵显示器的像素较多，对于单片机的计算能力和IO口的数量有一定要求。

因此，在编写程序的过程中，我们需要注意内存和资源的使用，避免发生卡顿或者无法正常显示的情况。

其次，点阵显示器的扫描速度要求较高，需要通过设置定时器的中断来实现，以确保显示的稳定性和清晰度。

通过本次实验，我们不仅掌握了单片机的基本原理和编程技巧，还深入了解了点阵显示器的工作原理和驱动方式。

通过自主设计和编写代码，我们成功实现了在16×16点阵上显示字符、数字和图案的功能。

这不仅加深了我们对嵌入式系统的理解，还提高了我们的动手实践能力和问题解决能力。

总之，通过这次实验，我们不仅学到了很多知识，还锻炼了自己的动手能力和团队合作能力。

虽然在实验过程中遇到了一些困难，但通过不懈努力和团队合作，我们最终取得了成功。

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。

(整理)点阵液晶模块LCD12864实例代码

一、概述带中文字库的128X64是一种具有4位/8位并行、2线或3线串行多种接口方式，内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64,内置8192个16*16点汉字，和128个16*8点ASCII字符集.利用该模块灵活的接口方式和简单、方便的操作指令，可构成全中文人机交互图形界面。

可以显示8×4行16×16点阵的汉字.也可完成图形显示.低电压低功耗是其又一显著特点。

由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。

基本特性:低电源电压（VDD:+3.0--+5.5V）显示分辨率:128×64点内置汉字字库，提供8192个16×16点阵汉字(简繁体可选)内置128个16×8点阵字符2MHZ时钟频率显示方式：STN、半透、正显驱动方式：1/32DUTY，1/5BIAS视角方向：6点背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10通讯方式：串行、并口可选内置DC-DC转换电路，无需外加负压无需片选信号，简化软件设计工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃二：模块主要硬件构成说明●忙标志:BF BF标志提供内部工作情况.BF=1表示模块在进行内部操作,此时模块不接受外部指令和数据.BF=0时,模块为准备状态,随时可接受外部指令和数据.利用STATUS RD指令,可以将BF读到DB7总线,从而检验模块之工作状态.●字型产生ROM（CGROM）字型产生ROM（CGROM）提供8192个此触发器是用于模块屏幕显示开和关的控制。

DFF=1为开显示（DISPLAY ON),DDRAM的内容就显示在屏幕上，DFF=0为关显示（DISPLAY OFF)。

DFF的状态是指令DISPLAY ON/OFF和RST信号控制的。

课程设计说明书基于arm的图形点阵lcd菜单设计--学位论文

编号：课程设计说明书(信息系统综合实训课程设计)题目：图形点阵LCD菜单设计院（系）：信息与通信学院专业：电子信息工程学生姓名：学号：指导教师：2016年 1月2日摘要目前图形点阵液晶显示模块广泛用于各式各样的电子设备，人机界面越来越直观形象，对于大多数用户来说，显示界面的友好与否，将直接影响到其产品的使用。

人机交互界面设计的目标是实现菜单窗口界面，用户可以在菜单方式下进行人机交互。

菜单响应用户的选择，根据用户的选择运行程序，实现相应的功能。

同时友好的人机界面使得电子设备更加易于维护。

本文在新唐Cortex-M0开发板设计了一种能实现四级深度的菜单，硬件部分由Cortex-M0主控芯片、12864LCD和3*3的矩阵键盘组成，通过软件部分循环扫描按键，并统计按下的按键，根据不同的需求在LCD上显示各种图片和文字。

图片和文字通过用取模软件进行取模可以转换成在LCD上显示所要求的格式。

通过将12864LCD看成一个平面坐标的形式，可以把大小合适的图片及文字放置到液晶屏合适的位置上。

基于此，我们实现了具有菜单查找、菜单返回、屏蔽错按等基本功能的四级深度的菜单设计。

关键词：菜单，Cortex-M0，LCDAbstractThe graphic dot matrix LCD module are widely used in all kinds of electronic equipment, man-machine interface is more and more intuitive image, for most users, display of friendly interface or not, will directly affect the use of its products. The human-computer interaction interface design goal is to achieve the menu window interface, users can be human-computer interaction in the menu mode. In response to user menu choice, according to the user's choice to run the program, realize the corresponding function. At the same time, friendly man-machine interface makes the device more easy to maintain.In this paper, Nuvoton Cortex-M0 development board is designed to achieve a depth of four menu, the hardware part by the Cortex-M0 main chip, 12864LCD and 3 * 3 matrix keyboard composition, part of the cycle by the software to scan button, and statistics press the button, depending on the needs of a variety of images and text displayed on the LCD. Pictures and text can be converted into modulo displayed on the LCD by performing the required format using modulo software. By plane coordinates 12864LCD as a form, you can put the right size of pictures and text is placed to the appropriate location on the LCD screen. Based on this, we have realized the find menu, the menu returns, shielding the wrong press and other basic functions of four depth of menu design.

点阵液晶汉字显示实验马敬松2008132217黄歆2008132218陈伟2008132203一、实验任务和要求用LCD128x64点阵液晶显示器显示指定汉字，最多可以显示4行、8个/行汉字，通过键盘可以随时改变显示的内容。

准备汉字字库不少于50个汉字。

二、实验方案论证及系统硬件电路设计12864点阵液晶显示模块由128*64个液晶显示点组成的一个128列*64行的阵列。

每个显示点对应一位二进制数，1表示亮，0表示灭。

要显示某个图形或汉字将相应的点阵信息写入到相应的存储单元中，并处理好显示点在液晶屏上的位置（行和列）与其在存储器中的地址之间的关系。

我们使用的液晶显示模块由两片列驱动器构成，也就是说12864液晶屏实际上是由左右两块独立的64*64液晶屏拼接而成，左右半屏驱动电路及存储器分别由片选信号CS1和CS2选择。

每一屏又分为八页，每页64列。

基于周立功实验开发板，实验电路如下：电路中，时为便于程序设计连线方式如下：A0（D\I）口连P3.0、A1口连P3.1(R\W)、A2口连P3.3（片选信号，P3.3为0时选CS1，否则选CS2）、RD 口连VCC、CS口连GND、WR(E)口连P3.2、RST口连VCC。

三、实验程序设计依据12864点阵液晶显示模块显示基本原理，对液晶屏操作前要判忙状态，对数据线DB0—DB7操作时分为下命令和写数据两个步骤（详细数据命令表和读写时序可查询器件使用手册），程序清屏及写数据显示均分屏、分页、按列处理。

其中读写时序如下：写操作时序读操作时序依据上述基本原理，部分程序框图如下：写左半屏一行程序框图字模提取采用软件提取方式纵向读取。

准备的字库和实验程序见附录。

四、实验结论通过调试，最终可实现每屏4行，每行8个汉字字符显示。

并可通过键盘切换显示的内容。

五、实验心得通过这次综合实验，我们小组有很多的心得体会，有关于单片机的，更多的是有关于人与人之间关系方面的。

在方案设计选择和芯片的选择上，培养了我们综合应用单片机的能力,对单片机的各个管脚的功能也有了进一步的认识。

LCD可分为段位式LCD、字符式LCD和点阵式LCD。

其中，段位式LCD和字符式LCD只能用于字符和数字的简单显示，不能满足图形曲线和汉字显示的要求；而点阵式LCD不仅可以显示字符、数字，还可以显示各种图形、曲线及汉字，并且可以实现屏幕上下左右滚动、动画、分区开窗口、反转、闪烁等功能，用途十分广泛。

由于LCD液晶显示具有显示字符、字母、汉字和图形的功能，它将用户需要显示的字符,字母或汉字进行编码，再将符合图形液晶显示模块规范的编码输入图形液晶显示模块，即可得到显示。

本文通过应用点阵式液晶图形显示控制器T6369C与单片机的接口及编程，在液晶屏上实现各种字符、汉字、数字、图形、曲线等的显示，并实现采集数据的波形曲线在液晶屏上的显示。

1．1 液晶显示模块的介绍液晶显示模块具有显示数字、字母、汉字和图形符号的能力，它是由点阵字符液晶显示器件和专用的行、列驱动器、控制器及必要的连接件，结构件装配而成。

图形点阵LCD液晶模块显示界面的可视化编程方案与实践样本

图形点阵LCD液晶模块显示界面的可视化编程方案与实践随着图形点阵LCD液晶显示模块在各行各业的逐步使用, 使得人机界面变得越来越直观, 特别对于国内大多数需要有汉字和图形显示的用户来说, 显示界面的友好与否, 将直接影响到其产品的形象和市场竞争力, 但一般涉及有关图形点阵液晶模块显示界面开发的技术人员由于缺乏经验而往往感到力不从心, 特别当用户的控制电路资源非常缺乏的条件下( 如家用电器) , 图形点阵液晶模块则更是望尘莫及, 而市面上所能见到的仍是那些"不顾客户死活而又自认清高"的传统型液晶显示模块, 虽然其成本已经降到普遍能接受的地步, 但还是因其控制方法的特殊性和复杂性严重阻碍液晶显示器的推广应用。

针对当前的这种状况, 深圳联合电子有限公司开发出一种图形点阵液晶模块, 将LCD所有的底层操作集成于模块内的MCU中, 这样其控制就变得极为容易, 占用户资源最少, 而且所有显示界面的编辑及调试全部在电脑上独立完程, 整个过程一目了然, 极大地方便用户编写显示界面的控制软件, 从而也提高了LCD液晶显示模块在产品中的附加值。

可视化编程LCD模组技术特性:1．模块显示点阵数( 分辨率) 128X64, 192X64, 256X64三种可选;2．内含高速MCU及64KB用户显示资料现场可编程FLASH;3．标准RS232串行通讯控制, 只占用户两根口线, 小马拉大车成为可能;4．配备仿真调试软件, 在电脑上独立完成显示界面的编辑, 资料下载, 仿真调试;5．简单又丰富的控制命令使模块显示的控制易如控制一只LED;6．用户可随时改写显示资料, 现场编程易如反掌, 显示界面无限升级;7．模块提供忙信号输出, 以检测模块状态;用户首先在电脑上完成LCD显示界面的编辑, 资料下载及仿真调试工作, 所配仿真调试软件可使用户方便的进行上述工作, 在硬件上除可视化编程LCD模组之外还配有一块电脑RS232电平转换转接板, 此板负责模块与电脑联接和对模块的供电, 模块与电脑联接图示如下。

点阵LCD取模软件使用说明

点阵LCD显示信息的取模
自由软件zimo221是个比较好用的点阵液晶取模软件（有需要的读者可以从网上下载），本节重点介绍使用该软件的使用方法。

第一步：打开zimo221.exe进入图x.1的主界面；
图x.1
第二步：取摸参数配置。

点击左下侧的“参数配置”按钮，再点击“其他选项”，弹出配置对话框后，按图x.2进行设置后确定保存；
第三步：取摸字体配置。

点击左下侧的“参数配置”按钮，再点击“文字输入区字体选择”会弹出相应配置对话框后，根据需要进行配置后确定保存；
第四步：输入字符。

在文字输入区输入一个待取输入待去字模的汉字或字符，然后按“Ctrl+Enter”组合键结束输入；
第五步：获取字模。

点击左侧的“取摸方式”按钮，再点击“C51 格式”或“A51 格式”，即可在点阵生成区生成相应的字模。

摘要
介绍了一种点阵ＬＣＤ菜单的编程方法，菜单项的有关显示信息存储在程序Ｒ将ＯＭ区，进行显示时，过查表获取在通

对于以上实例，单操作的过程可用图１示。要注意的菜表需是每次菜单从一级菜单进入二级菜单或从二级菜单返回到一级菜单时，单项值都会发生跳跃变化，要采用计算公式或查表菜需
