標(biāo)題: 單片機(jī)掉電保護(hù)程序的BUG
我在打萬年歷，給時(shí)間進(jìn)行賦值，加入掉電保護(hù)后，雖然能夠保護(hù)，但顯示的時(shí)間和我賦的值完全不一樣，哪位大神能幫我看看？

void xingqi()    //????????????
{
int yue=y ;
int nian=n  ;
int ri=r;
if(yue==2||yue==1)
{
   nian-=1;
  yue+=12;
}
num0=(ri+2*yue+3*(yue+1)/5+nian+nian/100+yue/400)%7-1;
switch(num0)
{
   case 0:P0=table[2];P2=0x04;break;
case 1:P0=table[3];P2=0x04;break;
case 2:P0=table[4];P2=0x04;break;
case 3:P0=table[5];P2=0x04;break;
case 4:P0=table[6];P2=0x04;break;
case 5:P0=table[7];P2=0x04;break;
   case 6:P0=table[8];P2=0x04;break;
}
}

用這個(gè)算法輸入年月日計(jì)算星期，本年的一月和二月算上一年的十三月和十四月，但是數(shù)碼管的月份顯示13，14，有什么建議嗎？
