本程序为调用系统时钟设计的一个汇编语言写的时钟程序

定时减法计数。输入数据0到9之间三位数，开始计时，每秒减一。当计数完成时，可做二次开发。还可做简单加减法-Timing counts subtraction. Input data between the three-digit 0-9, start running, by one per second. When the count is complete, do the secondary development. Also to do simple addition and subtraction

51单片机矩阵键盘扫描扫描之逐行扫描法.asm程序-51 single-chip scan matrix keyboard scanning method of progressive scan. Asm program

本代码为本人基于汇编语言的51单片机课程上机考试程序。;实验要求;利用P1/P2口或8255的接口电路和实验台上提供的六个数码管显示，设计一个电子钟，;电子钟设计如下格式   XX XX XX由左向右分别为时、分、秒;本人采用定时器溢出中断确定时间基准，main函数对共阴数码管进行动态扫描;p1口作为位选信号输出端;P2口作为段选信号输出端

用 AT89S51 单片机的定时 / 计数器 T0 产生一秒的定时时间，作为秒计数时间，当一秒产生时，秒计数加 1 ，秒计数到 60 时，自动从 0 开始。-with AT89S51 SCM timer/counter T0 produce than the regular time, seconds count as a time when a second time when, seconds count plus one, count to 60 seconds, the automatic starting from 0.
