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();
  }


  }  
}
