ABSTRACT
Electronic calendar and electronic thermometer with high accuracy, and show the advantages of appearance, are applied in shopping malls, family, hotels, banks, railway stations and other occasions. Electronic calendar with intuitive, easy to read display, versatile, simple circuit, low cost, and many other advantages, in line with the trend of development of electronic instrumentation, and has broad market prospects. It can on the year, month, week, day, hour, minute, second timing, but also the leap pensation function; temperature as the information indispensable in daily life, relationships, millions of households. With the continuous improvement of people's living standard, electronic calendar, or to gradually replace the traditional calendar, and more and more people are e.
This design microcontroller to STC89C52 as the main chip temperature sensor DS18B20 temperature measurement, the clock chip DS1302 real-time clock function, and LCD12864 LCD screen displays real-time clock, the current temperature and other information. Can develop students' basic knowledge of the dedicated chip bus technology, electronic circuits, microcontroller applications, especially in single-chip learning, has important practical significance.
Keywords: Single puter; electronic calendar; temperature sensor; liquid crystal display; keyboard
