1.使用PCF8563T实时时钟芯片与ZLG7290B显示电路结合起来,构成一时钟系统。
2.由8位数码管显示当前时间,并通过一按钮开关,不按下时显示“时、分、秒”,按下时显示“年、月、日”。
3.实现整点报时(共五声-前四声为低音,最后一声对应整点为高音)。
4.可以通过键盘来设定当前时间(时、分、秒)
-1 Use PCF8563T ZLG7290B display real-time clock chip and circuit combine to form a clock system. 2 of 8 digital tube display the current time, and through a push-button switch, the display when not pressing the " hours, minutes, seconds," when pressed displays " year, month and day." (3) to achieve the whole point timekeeping (a total of five sound- for the bass tones before finally heard the whole point corresponding to the treble). 4 can be set via the keyboard current time (hours, minutes, seconds)
