tim1定时器的配置和中断配置如下，帮忙看看有什么问题
void TIM1_INT_Config(void)
{
  NVIC_InitTypeDef NVIC_InitStructure;

/* TIM1 ʱÖÓʹÄÜ */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1 , ENABLE);
  /*  TIM1 ÖжÏǶÌ×Éè¼Æ*/
  NVIC_InitStructure.NVIC_IRQChannel = TIM1_BRK_UP_TRG_COM_IRQn;
NVIC_InitStructure.NVIC_IRQChannel = TIM1_CC_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
}

void TIM1_Toggle_Config(void)
{
  /* Time ¶¨Ê±»ù´¡ÉèÖÃ*/

  TIM_TimeBaseStructure.TIM_Prescaler = 0;
  TIM_TimeBaseStructure.TIM_ClockDivision = 0;
  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
  TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);
