单片机阳历转阴历程序 LCD12864电子钟制作

12864电子钟制作资料，共享给大家


单片机源程序如下:

1. 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。
   
2. /****************************************************/
   
3. /* 获取当前日期的农历及星期*/
   
4. /****************************************************/
   
5. /*==================================================*/
   
6. /*公历年对应的农历数据,每年三字节, 格式: */
   
7. /*第一字节BIT7-4 位表示闰月月份,值为0 为无闰月, */
   
8. /*BIT3-0 对应农历第1-4 月的大小*/
   
9. /*第二字节BIT7-0 对应农历第5-12 月大小, */
   
10. /*第三字节BIT7 表示农历第13 个月大小月份对应的位*/
    
11. /*为1 表示本农历月大(30 天),为0 表示小(29 天) */
    
12. /*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*/
    
13. /*类型:Byte:unsigned char Word:unsigned int */
    
14. /*本代码中Tim[0]/Tim[1]/Tim[2]分别为当前年月日数据*/
    
15. /*其中Tim[0]Bit7 表示世纪,1 为20 世纪19xx,0 为21 世纪20xx*/
    
16. /*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*/
    
17. /*==================================================*/
