基于51单片机的计算器的设计与研究王琨湖北工业大学，湖北，430068摘要:当今社会，随着人们物质生活的不断提高，电子产品已经走进了家家户户，无论是生活还是学习，还是娱乐和消遣几乎样样都离不开电子产品，大型复杂的计算能力是人脑所不能胜任的，而且比较容易出错。计算器作为一种快速通用的计算工具方便了用户的使用计算器可谓是我们最亲密的电子伙伴之一。设计计算器着重在于分析计算器软件的可开发过程中的环节和步骤，并从时间经验出发对计算器设计做了详细的分析和研究。单片机由于其微小的体积和极低的成本，广泛的应用于家电、工业控制等领域中。在工业生产中，单片微型计算机是微型计算机的一个重要的分支，也是颇具生命力的机种。单片微型计算机简称单片机，特别适用于控制领域，故又称微控制器。简易计算器是一种非常广泛日常工具，对现代社会越来越流行。它可以进行一些简易的计算。一般计算器是以AT89C51单片机为核心的简易计算器设计，输入采用4*4矩阵键盘，可以进行加、减、乘、除带符号数字运算（八位整数），并在液晶显示屏上静态显示操作的过程及结果。软件用C语言编程、Keil uVision2和protues仿真。关键词：单片机；计算器；液晶显示屏；矩阵键盘Abstract：In todays society, with the continuous improvement of peoples material life, electronic products has entered every household, whether it is life or learning or entertainment, and almost everything is inseparable from the electronic products, large and complicated calculation ability is human are not competent, and than the most error prone. As a quick and versatile tool for computing, the calculator is one of our most intimate partners. Design calculator focuses on the analysis of the process of the development of the calculator software in the process of links and steps, and from time to time experience in the design of the calculator to do a detailed analysis and research. SCM because of its small size and very low cost, widely used in home appliances, industrial control and other fields. In industrial production, the single chip micro computer is an important branch of micro computer, and also quite viable models. Single chip microcomputer for short, especially for the control field, it is also known as micro controller.Simple calculator is a very wide range of everyday tools, increasingly popular in modern society. It can make some simple calculations.The calculator is based on the AT89C51single-chip microcomputer as the core of a simple calculator design, using 4*4matrix keyboard input, you can add, subtract, multiplication, except the symbol digit operation ( eight integers ), and static display operation process and result in the screen LCD.
