描述: 8位共阴数码管时钟,显示88-88-88样式,正常走时的时候,两个“-”0.5秒闪烁一次;
调时:按KEY1按键第1次分钟位闪烁,再按KEY2一次分钟加1,按KEY3一次分钟减1,长按连加连减;
按KEY1按键第2次小时位闪烁,再按KEY2一次小时加1,按KEY3一次小时减1,长按连加连减;
按KEY1按键第3次,秒从零开始累加,时钟回到正常走时;
对时的时候先调好时、分,分钟要比参考时间的分钟加1分,
再看参考时间的秒数到了59再按KEY1按键的第3次,这样对时可以很准的
仿真 实物都通过. 11.0592MHz晶振,STC89C52RC,两个74HC573锁存器做位选、段选(Descr iption: 8 common Yin digital tube clock, display 88-88-88 style, when normal travel time, two "-" 0.5 seconds flicker once. Adjust time: press KEY1 button for first minutes to flicker, press KEY2 for one minute plus 1, press KEY3 for one minute to reduce 1, long press plus plus minus. Press the KEY1 button for second hours to flicker, press KEY2 for one hour plus 1, press KEY3 for one hour to reduce 1, long press plus plus minus. Press KEY1 button third times, seconds from zero to accumulate, the clock back to normal travel time; When the time is first adjusted, the minutes are 1 minutes longer than the reference time. Look at the seconds of reference time to 59 and press the KEY1 button for third times. Simulation objects are passed. 11.0592MHz crystal oscillator, STC89C52RC, two 74HC573 latches for bit selection, Duan Xuan.)
