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.
