Bạn thử sửa lại code trên đó thành như này xem sao

#include <16f877a.h>
#fuses HS, NOWDT
#use delay(clock=4000000)
#byte portb=0x06
#byte trisb=0x86
#byte INTCON=0x0b
#bit TMR0IF=INTCON.2
#byte TMR0=0x01
#use fast_IO (b)
   
   int a,b=0;
   int C[10]= {0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90 };
#int_rtcc
void rtcc()
{
   if(b++==250)
   {
      a++;
      if(a==10) a=0;
   }
}   
void main ()
{
   setup_timer_0 (RTCC_INTERNAL|RTCC_DIV_16);
   set_timer0 (6);
   enable_interrupts(int_rtcc);
   enable_interrupts(global);
   set_tris_b (0x00);
   a=0;
      while (true)
      {
      //for (a=0;a<=9;a++)
      //{
      //tre1s (250);
      portb=C[a];
      //tre1s (250);
      }
}
