摘　　要：利用Atmega8单片机作为控制核心部件,选用DS1302芯片作为时钟信号源,通过软件程序读写时钟数据,设计出了LED屏显多功能电子日历。详细地给出了Atmega8单片机与DS1302及LED点阵屏的硬件接口电路和部分软件程序。系统设计是在Proteus平台上进行软、硬件交互仿真,实现设计目的之后进行实物制作。从实物运行中观察到LED屏显日历计时准确,性能稳定,效果良好。还能滚动显示一些广告。Atmega8 microcontroller is used to do as a core component of control. DS1302 is chosen a source of clock signal. The clock signals is read and wrote by software program, the calendar of LED display screen has been designed. The emphases focus on the interface hardware electric circuit and software program on the Atmega8 microcontroller, DS1302 and LED display screen in this article. The system hardware and software interactive simulation is completed on the platform of Proteus, the purpose of the design has been presented, then the actual product can be made successfully. From the actual operation is observed that the calendar of the LED display screen accounts accurate timer, the function is stable and good effects is obtained. It can also roll to display some advertisement phrases.
