單片機(jī)源程序如下:
  1. 經(jīng)過(guò)本人對(duì)函數(shù)的優(yōu)化修改，編譯后代碼比原來(lái)少了近300 字節(jié)。
  2. /****************************************************/
  3. /* 獲取當(dāng)前日期的農(nóng)歷及星期*/
  4. /****************************************************/
  5. /*==================================================*/
  6. /*公歷年對(duì)應(yīng)的農(nóng)歷數(shù)據(jù),每年三字節(jié), 格式: */
  7. /*第一字節(jié)BIT7-4 位表示閏月月份,值為0 為無(wú)閏月, */
  8. /*BIT3-0 對(duì)應(yīng)農(nóng)歷第1-4 月的大小*/
  9. /*第二字節(jié)BIT7-0 對(duì)應(yīng)農(nóng)歷第5-12 月大小, */
  10. /*第三字節(jié)BIT7 表示農(nóng)歷第13 個(gè)月大小月份對(duì)應(yīng)的位*/
  11. /*為1 表示本農(nóng)歷月大(30 天),為0 表示小(29 天) */
  12. /*第三字節(jié)BIT6-5 表示春節(jié)的公歷月份,BIT4-0 表示春節(jié)的公歷日期*/
  13. /*類型:Byte:unsigned char Word:unsigned int */
  14. /*本代碼中Tim[0]/Tim[1]/Tim[2]分別為當(dāng)前年月日數(shù)據(jù)*/
  15. /*其中Tim[0]Bit7 表示世紀(jì),1 為20 世紀(jì)19xx,0 為21 世紀(jì)20xx*/
  16. /*Tim[10]為周數(shù)據(jù)/Tim[7]/Tim[8]/Tim[9]為農(nóng)歷數(shù)據(jù),根據(jù)需要自行更換*/
