请教个问题 陀螺仪怎么读值只读几次就不读了呢

贴出调试的程序



void TIM4_Config(unsigned short int Period,unsigned short int Prescaler)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
NVIC_InitTypeDef        NVIC_InitStructure;

RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);

TIM_TimeBaseStructure.TIM_Prescaler = Prescaler;    //ʱÖÓÔ¤·ÖƵ
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;//ÏòÉϼÆÊý
TIM_TimeBaseStructure.TIM_Period = Period;           //×Ô¶¯ÖØ×°Öµ
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;     //ʱÖÓ·ÖƵ1
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;   
TIM_TimeBaseInit(TIM4,&TIM_TimeBaseStructure);
TIM_ClearFlag(TIM4,TIM_FLAG_Update);
TIM_ITConfig(TIM4,TIM_IT_Update,ENABLE);      

NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn ;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;   //ÇÀÕ¼ÓÅÏȼ¶2
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;       //ÏìÓ¦ÓÅÏȼ¶0

这是我的定时器中断程序，我把定时器中断隐了就能连续读值了

打开定时器中断我调试的时候程序一直在跑，没有卡死。陀螺仪就是不返回值
