/********************************************************
**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：
**		1、HEX->BCD子函數hex_bcd()
**		2、顯示子函數display()
**		3、鍵盤子函數key()
**		4、時鐘子函數time()
**		5、日歷子函數day()
**		6、顯示控制子函數discommond()
**		7、定時器中斷0	time0()
**		8、初始化子函數 begin().
**		9、初始屏顯display_begin().
**		10、時間屏顯display_time().
**		11、潤年判斷leapf().
**現有問題:鍵盤修改程序還未完成
**			程序不夠精簡
