基于89C51的LCM12832模块128X64点阵液晶应用(验证OK)

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