文档编号:JD1198 文档字数:17690 基于单片机的简易计算器的设计 摘要:本文叙述了一种基于单片机的简易计算器的设计过程。该设计采用C语言编写简易计算器的加、减、乘、除基本运算程序。通过单片机、键盘数码管驱动芯片HD7279A、数码管以及相应按键的组合来实现上述功能。该系统在计算器基本运算功能实现的基础上,对计算器的记忆功能和计算精度进行了拓展,最终使计算器计算位数达到8位,计算精度达到小数点后2位。
Abstract:This article expatiates the process of one design of the simplified calculator based on single-chip computer. The program of the addition , subtraction, multiplication and division defined as the basic function of simplified calculator is written by C language . The above functions are realized by the combination of the single-chip computer, digital tube & keyboard driver chip HD7279A , digital tube and correspond key. Based on the realizing of the basic function of the simplified calculator, the system was developed on the funtions of saving result and advancing precision. The number of digit bit in this system reaches 8,while the compute precision reaches two decimal palces. Keywords:calculator;single-chip computer;digital tube;keyboard;driver chip
