Based on a Single Chip Microcomputer to Realize Electronic Clock Design and Analysis

Abstract

The clock, since the beginning of the day of human invention, it has become an essential thing in people's life, but with the continuous development of the times and science and technology, people pay more and more attention to the time concept, so the higher the accuracy of time. So we need to design a new type of electronic clock. Electronic clock is the use of digital circuit to display minutes, when the device, compared with the traditional mechanical clock, it has a time accurate, intuitive display, no mechanical transmission device, etc., so it is widely used. With the continuous improvement of people's living environment, and the beautification of the digital electronic clock can be seen in many occasions. Among them, in order to achieve the use of single-chip electronic clock is the most common, its main features are: programming flexible, easy to expand the electronic clock function, the use of electronic clock issued a variety of control signals, high accuracy. This paper mainly introduces the method of realizing the electronic clock with the timer counter in the chip microcomputer. The design consists of a single chip microcomputer electronic clock with the necessary circuit, which is based on AT89S52 chip and LED digital tube. Compared with the traditional mechanical watch, it has a more powerful and perfect function. Its time period is 24 hours, it is marked with 59 seconds, in addition, it also has the function of the school.
