这是我第一个STM32的单片机的例子,以前使用过STM8S系列的单片机.
我用TIM1 测试中断,它就是死活进不了中断,郁闷呀,哪位大虾帮忙看看,问题出在哪里.下面是我的例程.
void RCC_Configura(void)
{        RCC_DeInit();
        RCC_APB2PeriphResetCmd(RCC_APB2Periph_TIM1, ENABLE);
        RCC_HSEConfig(RCC_HSE_ON);
        RCC_APB1PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOD| RCC_APB2Periph_AFIO, ENABLE);
        //SystemInit();                
}

           GPIO_InitStructure.GPIO_Pin = LED1|LED2|LED3|LED4;
           GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
           GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
           GPIO_Init(GPIOD, &GPIO_InitStructure);
        GPIO_SetBits(GPIOD,LED1|LED2|LED3|LED4);
}
//-----------------------------------------------------------------------
void TIM1_Configure(void)
{        TIM_TimeBaseInitTypeDef TIM1_InitStructure;
        //TIM_DeInit(TIM1);
        TIM1_InitStructure.TIM_Prescaler =         0x0;
        TIM1_InitStructure.TIM_CounterMode = TIM_CounterMode_Up;
        TIM1_InitStructure.TIM_Period = (10000-1);
        TIM1_InitStructure.TIM_ClockDivision = TIM_CKD_DIV1;
        TIM1_InitStructure.TIM_RepetitionCounter = 0;
        TIM_TimeBaseInit(TIM1,&TIM1_InitStructure);         /*SET TIM1 VAUALE*/
        TIM_ClearITPendingBit(TIM1,TIM_IT_Update);       
        TIM_ITConfig(TIM1,TIM_IT_Update,ENABLE);
//        TIM_SetCounter(TIM1,0);
//        TIM_SetAutoreload(TIM1,0X100);
        TIM_Cmd(TIM1,ENABLE);               
}
//-------------------------------------------------------------------
void  Interrupt_Configure(void)
{        NVIC_InitTypeDef NVIC_InitStructure;
        /* Set the Vector Table base address at 0x08000000 */
          NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0000);
        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
        NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_IRQn;
          NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
          NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
          NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
}
//-----------------------------------------------------------------------------

int main(void)
{        RCC_Configura();
           GPIOD_Configure();
        TIM1_Configure();
        Interrupt_Configure();
        GPIO_ResetBits(GPIOD, LED1|LED3);
           while (1)
          {        GPIO_SetBits(GPIOD,LED4);
                delay(1000000);
                GPIO_ResetBits(GPIOD,LED4);
                delay(1000000);       
         }
}
