基于郭天祥单片机数码管的电子钟(含闹钟、整点报时)

基于单片机数码管的电子钟(郭天祥系列单片机)

功能说明

(D本电子钟可以显示当前时刻、年月日和闹钟时刻。不同时间的显示可以用key4来切换。

(2)、独立键盘key—key4(左到右)调节不同功能，7段数

码管显示。

(3)整点提示功能:当时间为整点时,蜂鸣器会滴滴滴响，响20秒；

(4)闹铃功能:本程序有闹铃功能，当定时时间到时，闹铃会滴滴滴报警，报警30秒；

(5)附加功能:当在闹铃和整点时,8个发光二极管会闪亮;

(6)时、分、秒之间和年、月、日之间也是用分割。

2、键盘控制

(1)key1-键移动调整单位，每按一次移动一个单位，可调整时分秒、年月日和闹钟时间。比如：在显示时分秒时，按下keyl 键, 可通过key2和key3对'秒'加减；再按一下keyl,可对"分'加减;再按一下keyl,可对"时'加减；再按keyl,时间开始走动

(2)key2-加 1 ； key3-减 1;

(3)key4-键切换时分秒、年月日和闹铃时间的显示。比如：当前为时分秒，按一下key4,则显示年月；再按一下，则显示闹铃时间；再按一下，则显示时分秒时间。
