HK32F030MF4P6 TIM2定时器例程如下

/*配置TIMER*/

// ALR_Time_Init(100,31); // 32Mhz主频 100us定时器
void ALR_Time_Init(uint16_t arr, uint16_t psc)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
NVIC_InitTypeDef NVIC_InitStructure;

/* Enable periph clock */
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

   /* Time base configuration */
   TIM_TimeBaseStructure.TIM_Period = arr;
   TIM_TimeBaseStructure.TIM_Prescaler = psc;
   TIM_TimeBaseStructure.TIM_ClockDivision = 0;
   TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

/* TIM2 enable counter */
TIM_Cmd(TIM2, ENABLE);

/* TIM Interrupts enable */
TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE);

   /* Enable the TIM2 gloabal Interrupt */
   NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
   NVIC_InitStructure.NVIC_IRQChannelPriority = 0;
   NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
   NVIC_Init(&NVIC_InitStructure);
}
void TIM2_IRQHandler(void)
{
   if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET)
   {
LED =! LED;
       TIM_ClearITPendingBit(TIM2, TIM_IT_Update);
   }
}
