单片机阳历转阴历程序 LCD12864电子钟制作 -

经过本人对函数的优化修改，编译后代码比原来少了近300 字节。
/****************************************************/
/* 获取当前日期的农历及星期*/
/****************************************************/
/*==================================================*/
/*公历年对应的农历数据,每年三字节, 格式: */
/*第一字节BIT7-4 位表示闰月月份,值为0 为无闰月, */
/*BIT3-0 对应农历第1-4 月的大小*/
/*第二字节BIT7-0 对应农历第5-12 月大小, */
/*第三字节BIT7 表示农历第13 个月大小月份对应的位*/
/*为1 表示本农历月大(30 天),为0 表示小(29 天) */
/*第三字节BIT6-5 表示春节的公历月份,BIT4-0 表示春节的公历日期*/
/*类型:Byte:unsigned char Word:unsigned int */
/*本代码中Tim[0]/Tim[1]/Tim[2]分别为当前年月日数据*/
/*其中Tim[0]Bit7 表示世纪,1 为20 世纪19xx,0 为21 世纪20xx*/
/*Tim[10]为周数据/Tim[7]/Tim[8]/Tim[9]为农历数据,根据需要自行更换*/
