#include <mega88.h>
#define LowPower PORTB &= 0xfe;
#define HighPower PORTB |= 0x01;
#define uchar unsigned int
void main(void)
{
uchar i,j = 0;
DDRB = 0x01;
TCNT0 = 0;
TCCR0B = 0x05; //分频F/1024
while(1)
{ //等待1S，4000000/1024/256/15=1Hz
for(i=0 ;i<15 ;i++)
{
while(TIFR0.0 = 0);
TIFR0.0 = 0;
}
if(j)
{LowPower; j = 0;}
else
{HighPower;j = 1;}
}
}
这个在PB0脚2S内变换一次高低电平，请帮我看看我的程序对吗？
