ABSTRACT

Modern Industrial Revolution represents the characteristic is the computer products and applications, and along with the computer technology the deepening of innovation and development, based on computer the thinking patterns of the core technology of electronic products has gradually as inseparable and important component of human social life, the typical representative is: effective recording time electronics products. The graduation design topic is: Design of digital calendar based on MCU, using AT89S52 as the core of digital calendar control processor system with serial chip DS1302 calendar to record time AT89S52 as the core of digital calendar control processor can leap year compensation and accurate. In this paper, the design digital calendar, can meet the user for temperature detection function, chip selection is widely used and powerful chip, and a liquid crystal display panel having strong anti-interference ability, as the interface of the digital calendar. This calendar with data read is very convenient, feature rich, the circuit looks very simple and the manufacturing cost is not too high and the advantages. Therefore, there will be a very good market prospects. It can be through the design of a design based on single chip digital calendar, an effective solution to the problems existing in the existing product. Therefore, in pushing the market has a good application value.
