/********************************************************
**這個程序是時鐘程序用LCM12832作為顯示.
**P1口作為鍵盤輸入P1.0=增加鍵；P11為選擇鍵
**時鐘顯示格式為：“時：分：秒”字體為16*16點陣
**修改方式為兩鍵式選擇鍵合修改鍵
**還可顯示萬年歷：“年：月：日”
**需要子函數(shù)：
** 1、HEX->BCD子函數(shù)hex_bcd()
** 2、顯示子函數(shù)display()
** 3、鍵盤子函數(shù)key()
** 4、時鐘子函數(shù)time()
** 5、日歷子函數(shù)day()
** 6、顯示控制子函數(shù)discommond()
** 7、定時器中斷0 time0()
** 8、初始化子函數(shù) begin().
** 9、初始屏顯display_begin().
** 10、時間屏顯display_time().
** 11、潤年判斷l(xiāng)eapf().
**現(xiàn)有問題:鍵盤修改程序還未完成
** 程序不夠精簡
