人類最早使用的定時工具是沙漏或水漏，但在鐘表誕生發(fā)展成熟之后，人們開始嘗試使用這種全新的計時工具來改進定時器，達到準 確控制時間的目的。 關鍵詞 ： 單片機，時鐘芯片，液晶模塊，定時控制 Subject： Development of Time Controller Based on Single Chip Microprocessor ABSTRACT Along with the electronic technology rapid development, appears of the large scale integrated circuit specially, these have made a big change on people’s living. Products including the technology application of the single chip microprocessor sets already entered every family. As one application of the single chip microprocessor technology, the time controller has been applied in the daily life, the industry situation and military field. This article introduced mainly the design process of the time controller posed by the single chip microprocessor. As the main control ponent, the single chip microprocessor is the core of the device and it plays the main control action. The clock chip provides a digital clock for the device and helps to realize the function of the timing control. The liquid crystal display is the carrier for th
