单片机掉电保护程序的BUG

ID:480106 · 发表于 2019-2-24 20:48

我在打万年历，给时间进行赋值，加入掉电保护后，虽然能够保护，但显示的时间和我赋的值完全不一样，哪位大神能帮我看看？

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;
}
}

用这个算法输入年月日计算星期，本年的一月和二月算上一年的十三月和十四月，但是数码管的月份显示13，14，有什么建议吗？
