SCM since the 20th century since the advent of the 1970s, with its high cost performance, by the people's attention and concern, a very wide application, developed very quickly. 51 SCM SCM is the most typical and most representative one.
The design of a 89 S51 chip as the core, supplemented by the necessary external circuit, designed a simple electronic clock, from 5 V DC power supply. In terms of hardware, in addition to CPU, using a total of six six anode of the digital display, LED using a dynamic scan showed that the use of the code drive 74 HC573 chip to drive. Through the LED can accurately display hours, minutes and seconds. Four-way stand-alone keys to achieve the time for change. Software using assembly language programming. The entire electronic system can be completed 10 minutes of time, transfer, the regular alarm clock, reset, and other functions.
Through the SCM minimum system circuit design principles let me gain a better understanding of the basic circuitry of the microcontroller, how to control timer interrupt programming and the basic methods, PCB design of ideas, the master circuit board welding skills and practical , Programming methods, testing and decomposition. I thus tempered the study, design and development of software and hardware capabilities.

单片机自20世纪70年代问世以来，以其极高的性能价格比，受到人们的重视和关注，应用很广、发展很快。而51单片机是各单片机中最为典型和最有代表性的一种。
本次设计以89S51芯片为核心，辅以必要的外围电路，设计了一个简易的电子时钟，它由5V直流电源供电。在硬件方面，除了CPU外，使用六个6位共阳极数码管进行显示，LED采用的是动态扫描显示，使用段码驱动器74HC573芯片进行驱动。通过LED能够比较准确显示时、分、秒。4路独立式按键实现对时间的调整。软件方面采用汇编语言编程。整个电子钟系统能完成时间的显示，调时，定时闹钟，复位等功能。
通过这次单片机最小系统电路原理设计让我更深入了解了单片机的基本电路，如何控制定时器和中断编程的基本方法，PCB设计分析思路，掌握了电路板焊接技巧和实际操作，程序设计方法、调试和分解。从而锻炼了我学习、设计和开发软、硬件的能力。

The monolithic integrated circuit has come out since the 1970s, by it extremely high performance price compared to, is valued people's and the attention, the application is very broad, the development to be very quick. But 51 monolithic integrated circuits are in various monolithic integrated circuits are most typical and the most representative one kind. this design take the 89S51 chip as a core, auxiliary by necessity peripheral circuit, has designed a simple electronic clock, it by 5V direct-current power supply power supply. In the hardware aspect, besides CPU, uses six 6 altogether anode nixietubes to carry on the demonstration, what LED uses is the dynamic scanning demonstrated that the use section code driver 74HC573 chip carries on the actuation. Through LED can when the quite accurate demonstration, divides, the second. 4 group free standing pressed keys realize to the time adjustment. The software aspect uses the assembly language programming. The entire electron clock system can complete the time the demonstration, the timing, fixed time alarm clock, functions and so on replacement. was smallest through this monolithic integrated circuit the system circuit principle design to let my inquire deeply monolithic integrated circuit's basic electric circuit, how to control the timer and the interrupt programming essential method, the PCB project analysis mentality, has mastered the circuit wafer welding skill and the actual operation, the programming method, the debugging and the decomposition. Thus exercised me to study, the design and to open becomes tender, hardware's ability.
