标题: 关于IO引脚问题
大家看看这段程序 #include <hidef.h>    /* common defines and macros */
#include "derivative.h"    /* derivative-specific definitions */

void main(void)
{
  /* put your own code here */
EnableInterrupts;
DDRB=0x01;
PORTB_PB0=0;
if(PORTB_PB1==0)
PORTB_PB0=1;


  for(;;) {
_FEED_COP(); /* feeds the dog */
  } /* loop forever */
  /* please make sure that you never leave main */现在我把脚 PORTB_PB1=0但PORTB_PB0不等于1
}
