/************* 本程序功能说明 **************
读写RTC, IC为PCF8563.
用STC的MCU的IO方式控制74HC595驱动8位数码管。
用户可以修改宏来选择时钟频率.
使用Timer0的16位自动重装来产生1ms节拍,程序运行于这个节拍下, 用户修改MCU主时钟频率时,自动定时于1ms.
用户可以在显示函数里修改成共阴或共阳.推荐尽量使用共阴数码管.
8位数码管显示时间(小时-分钟-秒).
行列扫描按键键码为17~32.
按键只支持单键按下, 不支持多键同时按下, 那样将会有不可预知的结果.
键按下超过1秒后,将以10键/秒的速度提供重键输出. 用户只需要检测KeyCode是否非0来判断键是否按下.
调整时间键:
键码17: 小时+.
键码18: 小时-.
键码19: 分钟+.
键码20: 分钟-.
