Description: With the rapid development of electronic technology, especially with the emergence of large-scale integrated circuits, it has brought fundamental changes to human life. It is a single chip microcomputer application product has entered thousands of households. The electronic calendar has brought many conveniences to people's life.
This paper describes the working principle of the system hardware, each accompanied by a diagram of the system structure, introduced this system by the application of the hardware interface technology and the function of each interface module and the work process, secondly, expounds the application of various modules and implementation process. The design is based on the digital integrated circuit technology, the single chip microcomputer technology is the core. The main idea written in this paper is the combination of software and hardware, which is based on hardware, and the preparation of functional modules.
This system by single chip microcomputer C language for software design, increase the readability and portability of the program, to facilitate the expansion and changes to the design of the software adopts modular structure, make the program design more concise and clear logical relations. The system can display the data through the dot matrix liquid crystal, so it has the humanized operation and beautiful page effect. Display time, lunar calendar, week, temperature, solar terms, dry ground and sunrise sunset times, and alarm and intelligent control of household electrical appliances.
