2 **这个程序是时钟程序用LCM12832作为显示.
3 **P1口作为键盘输入P1.0=增加键；P11为选择键
4 **时钟显示格式为：“时：分：秒”字体为16*16点阵
5 **修改方式为两键式选择键合修改键
6 **还可显示万年历：“年：月：日”
7 **需要子函数：
8 ** 1、HEX->BCD子函数hex_bcd()
9 ** 2、显示子函数display()
10 ** 3、键盘子函数key()
11 ** 4、时钟子函数time()
12 ** 5、日历子函数day()
13 ** 6、显示控制子函数discommond()
14 ** 7、定时器中断0 time0()
15 ** 8、初始化子函数 begin().
16 ** 9、初始屏显display_begin().
17 ** 10、时间屏显display_time().
18 ** 11、润年判断leapf().
19 **现有问题:键盘修改程序还未完成
20 ** 程序不够精简
