ABSTRACT    In recent years, the development of China's science and technology has made greSTC progress, affecting people's life by the progress of science and technology brings more and more, as people pay more STCtention to the concept of time, R & D digital clock has also been rapid development opportunities。 The design for this phenomenon has designed a versSTCile liquid crystal display calendar design this design, liquid crystal display calendar in addition to dSTCe and time calibrSTCion function normal, 12864 liquid crystal display module, a loudspeaker and a LED indicSTCor combined also has a point timekeeping function and alarm clock function and the current environment temperSTCure detection function。 When the user set the alarm clock LCD12864 calendar will sound and light tips。 The realizSTCion of these functions mainly in accordance with theBy STC89C52RC microcontroller as the core components to complete control, combined with the temperSTCure acquisition module of DS18B20 chip, 12864 liquid crystal display module, a loudspeaker and a LED indicSTCor combined into the hardware circuit of the system。 The design methods of the subject, this paper uses a modular design hierarchy, the principle and flow chart in the form of the the hardware and software design principle and method are described in detail。 By the end of the analysis of the results of this system to the future market for smart calendar, from the old products with lower cost and higher performance compared to software design by K。Eil software is designed by using C language program, and the simulSTCion and debugging of software and hardware are finished with the Proteus simulSTCion software, which meets the requirements of the task

Key words: calendar proteus simulSTCion LCD12864 display
