3、pe intelligent domestic electric appliances appear in our life one after another. Calendars are necessary daily goods in peoples life. But they are generally paper goods with inconvenient use and short life. Electronic calendar adopts the technology of intelligent electronic control and display, and
4、 then improves the deficiency of paper calendars. The design adopts the core of AT89S52 single chip microcomputer, which constitutes controlling circuit, and integrates DS1302 clock chip and 24C02FLASH memory, which achieve self-adjusting of time and no power protecting. LCD displays all information
5、. Time and date adjusting is carried out by three keys, which can also set the alarm clock. The calendar can display solar and lunar year, month, day, week, hour, minute, second. When displaying lunar months, leap month is showed. Keywords: electronic calendar 52 series single chip microcomputer clock chip flash memory LCD 目 录 1 引言
