一个简单的AVR测试程序

#include<iom16v.h>

#include<macros.h>

unsigned char led[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};

void delay( )                       

{

   int i,j;

   for(i=0;i<56;i++)

   for(j=0;j<77;j++);

   }

void main(void)

{

  int i,j;

  DDRB=0xff;

  while(1)

  {

    PORTB=0b11111111; 

    for(i=0;i<=7;i++)

    {

     

    PORTB=led[i];

	delay();

	}

	

	 

  }  

}
