void EXTI0_IRQHandler(void)
{
  delay_ms(10); //消抖
if(WK_UP==1)
{
LED0=!LED0;
LED1=!LED1;
}
EXTI_ClearITPendingBit(EXTI_Line0);  //清除EXTI0线路挂起位
}
void EXTI9_5_IRQHandler(void)
{
delay_ms(10); //消抖

if(KEY0==0) {

         foreward();

}
   EXTI_ClearITPendingBit(EXTI_Line5); //清除LINE5上的中断标志位
}

void EXTI15_10_IRQHandler(void)
{
  delay_ms(10); //消抖
  if(KEY1==0)
{

      rollback();
}
   EXTI_ClearITPendingBit(EXTI_Line15);  //清除LINE15线路挂起位
}

void foreward(void)//正转函数
{
u16    led0pwmval;
u16       led1pwmval;
while(1)
{
delay_ms(10);
   led0pwmval=500;
   TIM_SetCompare1(TIM3,led0pwmval);

   led1pwmval=899;
   TIM_SetCompare1(TIM3,led1pwmval);

}
}

void rollback(void)//反转函数
{
u16    led0pwmval;
u16    led1pwmval;
while(1)
{
delay_ms(10);
   led0pwmval=899;
   TIM_SetCompare1(TIM3,led0pwmval);
   led1pwmval=300;
   TIM_SetCompare1(TIM3,led1pwmval);
}
}

有懂的不
