5、件设计时，没有良好的基础知识和实践经验会受到很大限制，每项功能实现时需要那种硬件，程序该如何编写，算法如何实现等，没有一定的基础就不可能很好的实现。在编写程序过程中发现以现有的相关知识要独自完成编写任务困难重重，在老师和同学的帮助下才完成了程序部分的编写。万年历的设计过程在硬件与软件方面进行同步设计。硬件部分主要由AT89C52单片机，LED显示电路，以及调时按键电路等组成。在单片机的选择上本人使用了AT89C52单片机，该单片机适合于许多较为复杂控制应用场合。显示器使用2片7SEG-MPX8-CA和一片7SEG-MPX4-CA。7SEG-MPX8-CA是一种八个共阳二极管显示器，7SEG-M
6、PX4-CA是一种四个共阳二极管显示器。为了能更轻松的控制这三片显示器，本人使用了3片74HC164来驱动。74HC164 是 8 位边沿触发式移位寄存器，串行输入数据，然后并行输出。软件方面主要包括日历程序、时间调整程序，公历转阴历程序，显示程序等。程序采用汇编语言编写，以便更简单地实现调整时间及阴历显示功能。所有程序编写完成后，在wave软件中进行调试，确定没有问题后，在Proteus软件中嵌入单片机内进行仿真。最后总在老师同学的帮助以及自己的努力下完成了此次电子万年历的设计。关键词：时钟电钟；DS1302；DS18B20；动态扫描；单片机 Abstract E-calendar day
7、time is a very wide range of tools, increasingly popular in modern society. It can be year, month, day, Sunday, hours, minutes, seconds for time, but also has a leap year compensation to a variety of functions, and the DS1302s long life, small error. For the digital electronic calendar using an intu

12、esign process in hardware and software to synchronize the design. Hardware mainly by the AT89C52 microcontroller, LED display circuit, and the tune composed of the circuit when the button. In the SCM choice I used the AT89C52 microcontroller, which is suitable for many of the more complex control applications. Monitor the use of two 7SEG-MPX8-CA and a 7SEG-MPX4-CA. 7SEG-MPX8-CA is a total of eight-yang diode display, 7SEG-MPX4-CA is a total of four-yang diode display. In order to more easily control the three monitors, I use thr
