5、ry,Ministersand基于MSP430单片机的电子时钟设计摘要多功能数字钟的应用非常普遍，由单片机作为数字钟的核心控制器， 通过它的时钟信号 进行实现计时功能，将其时间数据经单片机输出，利用显示器显示出来。通过键盘可以进行 校时，定时等功能。本系统利用单片机实现其具有计时、校时等功能的数字时钟.是以单片机MSP430F149为核心元件同时采用LCD12864同时显示“时、分、秒、星期、年、月、日、温度”的现代计时装置。显示极具人性化，另外具有校时功能，闹钟功能和节电保护功能。利用单片机实现的数字时钟具
6、有编程灵活，便于功能的扩充等优点，如在电路板上预留有电源输出，温度传感 插座等插座，便于功能扩展。关键词：MSP430F149 单片机 DS12887AbstractMulti-functiondigitalclockisverycommon,bysinglechipmicrocomputerasthecoreofthedigitalclockcontroller,throughitsfunctionoftimingclocksignal,thetimedatabytheMCUoutput,usingthem
