Abstract
In recent years along with the computer in the social domain seepage and the large scale integrated circuit development, the monolithic integrated circuit application was moving towards unceasingly thoroughly, because it had function, the volume was small, the power loss was low, the price was cheap, the work was reliable, characteristics and so on easy to operate, therefore suited specially in with the control related system, more and more widely applied in the automatic control, the intellectualized instrument, the measuring appliance, the data acquisition, the military proct as well as the domestic electric appliances and so on each domain, the monolithic integrated circuit often is took a core part used, in the basis concrete hardware architecture, as well as in view of the concrete application object characteristic software union, made the consummation.
Along with take the computer as the axle center various information processing installment birth, for will adapt this kind of new situation, the information electrical appliances, the network termination, use and so on broadcast - correspondence LCD markets is also rapid expands, not only moreover the present LCD development direction lies in the large screen, moreover in the small screen aspect, for example the automobile guidance system, the camera, the digital photographic camera, the portable television, PDA (personal digital assistant), the entertainment/mechanical games, the camera and so on has the further development.
Liquid-crystal display (LCD) has the merit which the power loss low, the volume small, the weight light, ultra thin and so on many other monitors are unable to compare, in recent years widely uses in the intelligent instrument, the measuring appliance and the low power loss electronic procts which the monolithic integrated circuit controls .LCD may divide into section type LCD, character type LCD and among lattice type LCD., section type LCD and character type LCD only can use in the character and the digital simple demonstration, cannot satisfy the graph curve and the Chinese character demonstration request; Not only but lattice type LCD may demonstrate the character, the numeral, but also may demonstrate each kind of graph, the curve as well as the Chinese character, the animation, and may realize functions and so on screen trundle, reverse, twinkle, the use is extremely widespread.
Thus it can be seen the LCD application is so widespread, therefore controls the liquid-crystal display with MPU is the very universal application. This topic main research realizes the liquid crystal mole character demonstration through the monolithic integrated circuit control.

㈣ 关于51单片机 的秒表/时钟计时器设计摘要
数字电子秒表具有显示直观、读取方便、精度高等优点，在计时中广泛使用。本设计用单片机组成数字电子秒表，力求结构简单、精度高为目标。
设计中包括硬件电路的设计和系统程序的设计。其硬件电路主要有主控制器，计时与显示电路和回零、启动和停表电路等。主控制器采用单片机AT89C52，显示电路采用共阴极LED数码管显示计时时间。
本设计利用AT89C52单片机的定时器/计数器定时和记数的原理，使其能精确计时。利用中断系统使其能实现开始暂停的功能。P0口输出段码数据，P2.0-P2.4口作列扫描输出，P1.1、P3.2、P3.3、P2.5口接四个按钮开关，分别实现开始、暂停、清零和查看上次计时时间功能。电路原理图设计最基本的要求是正确性，其次是布局合理，最后在正确性和布局合理的前提下力求美观。硬件电路图按照图1.1进行设计。
图1.1 数字秒表硬件电路基本原理图
根据要求知道秒表设计主要实现的功能是计时和显示。因此设置了四个按键和五位数码管显示时间，三个按键分别是开始，停止、复位和查看上次计时时间按键。利用这四个建来实现秒表的全部功能，而五位数码管则能显示最多99.999秒的计时。
本设计中，数码管显示的数据存放在内存单元79H－7DH中。其中79H存放毫秒位数据，7AH存放十毫秒位数据，7BH存放百毫秒位数据，7CH存放秒位数据，7DH存放十秒位数据，每一地址单元内均为十进制BCD码。由于采用软件动态扫描实现数据显示功能，显示用十进制BCD码数据的对应段码存放在ROM表中。显示时，先取出79H-7dH某一地址中的数据，然后查得对应的显示用段码，并从P0口输出，P2口将对应的数码管选中供电，就能显示该地址单元的数据值。
最终缓存区则设置为59H-5DH，数据存放规则和79H-7DH一样。分别对应存放毫秒位至十秒位数据。与79H-7DH存储区不一样的是：59H-5DH存储的内容为数字秒表上一次计时显示的时间。而79H-7DH为当前计时时间存储区。
计时采用定时器T0中断完成，定时溢出中断周期为1ms，当一处中断后向CPU发出溢出中断请求，每发出一次中断请求就对毫秒计数单元进行加一，达到10次就对十毫秒位进行加一，依次类推，直到99.999秒重新复位。
再看按键的处理。这四个键可以采用中断的方法，也可以采用扫描的方法来识别。复位键和查看主要功能在于数值复位和查询上次计时时间，对于时间的要求不是很严格。而开始和停止键则是用于对时间的锁定，需要比较准确的控制。因此可以对复位和查看按键采取扫描的方式。而对开始和停止键采用外部中断的方式。
设计中包括硬件电路的设计和系统程序的设计。其硬件电路主要有主控制器，显示电路和回零、启动、查看、停表电路等。主控制器采用单片机AT89C52，显示电路采用共阴极LED数码管显示计时时间，四个按键均采用触点式按键。
对于数字显示电路，通常采用液晶显示或数码管显示。对于一般的段式液晶屏，需要专门的驱动电路，而且液晶显示作为一种被动显示，可视性差，不适合远距离观看；对于具有驱动电路和单片机接口的液晶显示模块(字符或点阵)，一般多采用并行接口，对单片机的接口要求较高，占用资源多；另外，AT89S52单片机本身无专门的液晶驱动接口。而数码管作为一种主动显示器件，具有亮度高、响应速度快、防潮防湿性能好、温度特性极性、价格便宜、易于购买等优点，而且有远距离视觉效果，很适合夜间或是远距离操作。因此，本设计的显示电路采用7段数码管作为显示介质。
数码管显示可以分为静态显示和动态显示两种。由于本设计需要采用五位数码管显示时间，如果静态显示则占用的口线多，硬件电路复杂。所以采用动态显示。
图1.3 显示电路基本原理图
动态显示是一位一位地轮流点亮各位数码管，这种逐位点亮显示器的方式称为位扫描。通常各位数码管的段选线相应并联在一起，由一个8位的I/O口控制；各位的公共阴极位选线由另外的I/O口线控制。动态方式显示时，各数码管分时轮流选通，要使其稳定显示必须采用扫描方式，即在某一时刻只选通一位数码管，并送出相应的段码，在另一时刻选通另一位数码管，并送出相应的段码，依此规律循环，即可使各位数码管显示将要显示的字符，虽然这些字符是在不同的时刻分别显示，但由于人眼存在视觉暂留效应，只要每位显示间隔足够短就可以给人同时显示的感觉。
数码显示管分为共阳数码管和共阴数码管两种
共阳极数码管的8个发光二极管的阳极（二极管正端）连接在一起，如图1.4（b），通常，公共阳极接高电平（一般接电源），其它管脚接段驱动电路输出端。当某段驱动电路的输出端为低电平时，则该端所连接的字段导通并点亮，根据发光字段的不同组合可显示出各种数字或字符。此时，要求段驱动电路能吸收额定的段导通电流，还需根据外接电源及额定段导通电流来确定相应的限流电阻。
共阴极数码管的8个发光二极管的阴极（二极管负端）连接在一起，如图（c），通常，公共阴极接低电平（一般接地），其它管脚接段驱动电路输出端，当某段驱动电路的输出端为高电平时，则该端所连接的字段导通并点亮，根据发光字段的不同组合可显示出各种数字或字符。此时，要求段驱动电路能提供额定的段导通电流，还需根据外接电源及额定段导通电流来确定相应的限流电阻。
㈤ 单片机摘要怎么写
摘 要
LCD液晶显示已经是人机界面的关键技术。本文对基于单片机的LCD液晶显示器控制系统进行了研究。
首先在绪论中介绍了本课题的课题背景、研究意义及完成的功能。本系统是以单片机的基本语言C语言来进行软件设计，51的编程语言常用的有二种，一种是汇编语言，一种是C 语言。汇编语言的机器代码生成效率很高但可读性却并不强，复杂一点的程序就更是难读懂，而C 语言在大多数情况下其机器代码生成效率和汇编语言相当，但可读性和可移植性却远远超过汇编语言，而且C 语言还可以嵌入汇编来解决高时效性的代码编写问题。对于开发周期来说，中大型的软件编写用C 语言的开发周期通常要小于汇编语言很多。综合以上C 语言的优点，我在学习时选择了C 语言指令的执行速度快，节省存储空间。为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了。使硬件在软件的控制下协调运作。正文中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，并介绍了单片机微处理器的发展史，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, 并具体描述了AT89C51 AMPIRE128×64接电路接口的软、硬件调试。其次阐述了程序的流程和实现过程。本文撰写的主导思想是软、硬件相结合，以硬件为基础，来进行各功能模块的编写。
最后对我所开发的用单片机实现LCD液晶显示器控制原理的设计思想和软、硬件调试作了详细的论述。
