Based on the electronic clock ds12c887 the C Language Program

本源代码是单片机乒乓球实验，用89C51，74LS164和8255完成- The source code is the monolithic integrated circuit ping pong experiment, with 89C51, 74LS164 and 8,255 completes

这是用PIC单片机做的DTMF信号解码，用的是汇编语言。已经通过实验了。有兴趣的人可以看一下。-This is a single-chip microcomputer PIC to do with the DTMF signal decoding, using assembly language. Has passed the test. Those who are interested can look at.

自己动手制作一个MCS-51编程器，非常实用-yourself making a MCS-51 programmer, very practical

本设计实例包含了DS1302时钟+DS18B20，具有时钟显示和温度显示功能。包含源程序Proteus仿真。-This design example includes the DS1302 clock+ DS18B20, with a clock display and temperature display. Contains the source Proteus simulation.

8051f02x 单片机的实用排序子程序。-Singlechip 8051f02x practical sort subroutine.

本设计主要是运用单片机设计一个最小系统――电子时钟，它具有24小时计时功能，能够对时间进行调整，并且能实现时、分、秒的显示，同时还有内设闹钟，时间到时候会响铃，响铃时可以通过按键控制延时再启动或关断。与此同时还设置了整点报时功能；并采用采用了软件去抖的方法扫描键盘，动态刷新显示数码管，并通过查表实现译码输出时间等编程方法；-This design is the use of single-chip design of a minimum system- Electronic clock, it has a 24-hour timer function, capable of time to adjust, and can achieve the hours, minutes and seconds display, but also equipped with alarm clocks, time to When ringing the bell to ring when the button control can delay re-start or shutdown. At the same time also set up the whole point timekeeping function and adopt the use of the software to scan the keyboard shaking method, dynamic refresh display digital tube, and through the realization of decoding look-up table output time programming method
