基于单片机数码管的电子钟〔郭天祥系列单片机〕
1、功能说明
〔1〕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key1-key4(左到右〕调节不同功能，7段数码管显示。
&nbsp; &nbsp; (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；
&nbsp; &nbsp; (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；
&nbsp; &nbsp; 〔5〕附加功能:当在闹铃和整点时,8个发光二极管会闪亮；
&nbsp; &nbsp; 〔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。比方：在显示时分秒时，按下key1键，可通过key2和key3对‘秒’加减；再按一下key1，可对‘分’加减；再按一下key1，可对‘时’加减；再按key1，时间开场走动
〔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。比方：当前为时分秒，按一下key4，那么显示年月；再按一下，那么显示闹铃时间；再按一下，那么显示时分秒时间。
