求助，求助，做的数码管秒表显示是乱的

ti

照着视频做的简易数码管秒表显示是乱的，搞了我好几天都找不出原因，

  #include
typedef unsigned char uint8;
typedef unsigned int uint16;
typedef unsigned long uint32;
code uint16  number[] = { 0x3f,0x06,0x5b,
                        0x4f,0x66,0x6d,
            0x7d,0x07,0x7f,
               0x6f          } ;
uint16 counter=0;
uint8 b[6];
***it BCD6 = P1^0;
***it BCD5 = P1^1;
***it BCD4 = P1^2;
***it BCD3 = P1^3;
***it BCD2 = P1^4;
***it BCD1 = P1^5;

timer0()
{
TMOD|= 0x10;
TMOD&= 0xdf;
TH0  = 0x4c;
TL0  = 0x00;
TR0  = 1;
}

inter()
{
   ET0=1;
   EA=1;
}

refresh()
{
   static uint8 j=0;
   switch(j)
   {
      case 0: BCD6 = 0;  j++;  P0 = number[b[0]]; break;
   case 1: BCD5 = 0;  j++;  P0 = number[b[1]]; break;

   case 5: BCD1 = 0;  j=0;  P0 = number[b[5]]; break;
   default: break;
   }
}

inter_timer0()  interrupt  1
{
   static uint32 sec=0;
TH0=0x4c;

counter++;
   if(counter==20)

   }

}

main()

while(1);
}

P0和P1（0~5）直接接共阴数码管的单片机是stc89c52
高手给看看啦~·谢啦{:soso_e113:}

case 0: BCD6 = 0; j++; P0 = number[b[0]]; break;
j++是什么意思，不要看看

板凳

怎么把代码并在一行，看着好晕

单片机是STC89C52，你用 #include 干什么
应该用#include

我以为是一样的

中断应该是interrupt 3吧

安强 · 2012-10-5 16:09:34

现在你用的是定时器1，不是定时器0.所以应该进入中断是inter_timer0() interrupt 3
