基于MSP430单片机的电子时钟设计
摘要
电力系统谐波分析
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 校恶臭污染物排放标准
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。

Abstract情景模拟教学
Multi-function digital clock is very common, by single chip microcomputer as the core of the digital clock controller, through its function of timing clock signal, the time data by the MCU output, using the monitor display. Through the keyboard to school, timing, and other functions. This system using single-chip microcomputer to realize its timing, the functions such as digital clock. When the school is based on single chip MSP430F149 as the core element at the same time adopt LCD12864 display at the same time "the hours, minutes, seconds, year, month, day, week, temperature" modern timing devices. Shows highly hu
manized, the other has a school function, when my alarm clock and saving electricity protecting functions. Using singlechip microcomputer digital clock has a flexible programming, function expansion conveviently, such as reserved on the circuit board output power, temperature sensing socket outlet, such as convenient for function extension.
