Electronic perpetual calendar which is an application of the single-chip processor system, is combining by hardware and software. Hardware is composed of five modules： Main control unit, clock circuit, temperature test circuit, display circuit, keyboard interface. Main control module adopts AT89C52, clock circuit adopts the DS 12C887 clock chip, display module adopts the LCD, and temperature test adopts the DS 18B20 temperature sensor, keyboard interface circuit is completed by connecting ordinary button. Software takes language of C to program, Single-chip processor gets the time data through using the DS12C887 clock chip. The DS18B20 gathers temperature siguals and transmits them to single-chip processor. Lastly, the LCD displays solar calendar year, month, day, hour, minute, second, alarm clock, week and temperature.
