/********************************************************
**這個(gè)程序是時(shí)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(shí)鐘顯示格式為：“時(shí)：分：秒”字體為16*16點(diǎn)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(shí)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(shí)器中斷0 time0()
**  8、初始化子函數(shù) begin().
**  9、初始屏顯display_begin().
**  10、時(shí)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
