Present situation of electronic perpetual calendar

Electronic calendar is a modern digital timekeeping product, which uses an independent chip to control internal data operation, and uses LED digital display to display daily information such as date, time, week, solar terms and temperature, and combines many advanced electronic technologies and modern classic technologies. The compatibility between internal electronic board hardware and software, hardware and hardware is manifested in the static or dynamic driving of LED digital, such as whether there is flashing or broken pen. It is earthquake-resistant, fire-proof and riot-proof; There are many series and specifications of products, and the materials of products are also divided into glass, plastic, aluminum alloy and so on. Electronic calendar technology has entered the stage of optimizing the overall relationship among people, families and the environment, and is developing towards ultra-miniature, ultra-efficient and miniaturization of integrated circuits. At present, there are many kinds of digital calendars in the market, most of which are electronic systems designed based on single chip microcomputer technology. They are generally composed of input pulse circuit, single chip microcomputer, crystal oscillator and reset circuit, external storage circuit and LED display circuit. Nowadays, digital calendars are mainly used for timing, automatic time telling, timing, date inquiry and automatic control. Due to the development of single chip microcomputer technology and digital integrated circuit technology, today's digital calendar system has the advantages of small size, accurate timing, low power consumption, convenient maintenance, stable performance, accurate travel time and convenient carrying. In addition, there are ready-made digital calendar integrated circuit chips on the market, which are cheap and easy to use.
