코드비젼으로  9999 카운터를 실행해보았습니다
소스는
#include <mega128.h>
void delay(int a)
{                        
        int i,j;
        for(i=0;i<a;i++)                                        
                for(j=0;j<a;j++);
}
void main()
{
        int LEDNUM[] = {0xc0, 0xf9, 0xa4, 0xb0, 0x99, 0x92, 0x82, 0xd8, 0x80, 0x98};  //0~9
        int m,n,l,y,a;
        DDRA = 0xff;
        DDRB = 0xff;        
        while(1)
        {
                for(m=0;m<10;m++)
                {
                        for(n=0; n<10; n++)
                        {
                                for(l=0; l<10; l++){
                                        for(y=0; y<10; y++){  
                                                for(a=0;a<10;a++){
                                             PORTB=0xfe;                        
                                             PORTA = LEDNUM[y];
                                             delay(40);
                                             PORTB = 0xfd;
                                             PORTA=LEDNUM[l];
                                             delay(40);    
                                             PORTB = 0xfb;
                                             PORTA=LEDNUM[n];
                                             delay(40);
                                             PORTB = 0xf7;
                                             PORTA=LEDNUM[m];
                                             delay(40);           }
                                 }      
                            }
         }  
         }                      
}
}

이런식인데요
여기서 스위치를 추가해
led0000이다가 스위치를 키면
카운터가 다시 되는 소스를 만들어야하는데
저기서 어떻게 수정해야 할까요

도저히 감을 못잡아 올려봅니다

도와주세요
