电子万年历的设计方法很多,可选用可编程逻辑控制器或单片机为主控器进行设计,它其功能强大,使用方便,成本较低。本文以MCS-51系列单片机为主控芯片与DS1302时钟芯片组合设计了一种电子万年历,再配电源电路、按键电路和显示电路完成万年历硬件系统。试用表明,该万年历系统稳定可靠,具有一定的实用价值。 Many design methods of electronic calendar, the choice of programmable logic controller or microcontroller for the master design, its powerful, easy to use, low cost. In this paper, MCS-51 series microcontroller as the main control chip and DS1302 clock chip combination designed an electronic calendar, together with the power circuit, the key circuit and the display circuit to complete the calendar hardware system. Trial shows that the calendar system is stable and reliable, has a certain practical value.
