输出比较有脉冲输出，卡死在初始化后面的函数，注释后后面函数正常

会是哪里问题？

定时器配置问题吗？

GPIO_InitTypeDef GPIO_Structure;
TIM_TimebaseInitTypeDef  TIM_TimebaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;
NVIC_InitTypeDef NVIC_InitStructure;

//开定时器时钟

GPIO_Structure.GPIO_Mode = GPIO_Mode_AF_PP; //复用推挽输出
GPIO_Structure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA &GPIO_Structure);
GPIO_SetBits(GPIOAGPIO_Pin_1 | GPIO_Pin_6); //初始化引脚
//配置中断优先级
NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn; //中断源
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; //中断通道使能
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2; //抢占优先级
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1; //响应优先级
NVIC_Init(&NVIC_InitStructure); //初始化
NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn; //中断源

// 自动重装载寄存器的值，累计TIM_Period+1个频率后产生一个更新或者中断  即周期
TIM_TimebaseStructure.TIM_Period = 1000 - 1; //周期
TIM_TimebaseStructure.TIM_Prescaler= 360-1;// 时钟预分频数
TIM_TimebaseStructure.TIM_ClockDivision = TIM_CKD_DIV1; //时钟分割 0
TIM_TimebaseStructure.TIM_CounterMode = TIM_CounterMode_Up; //向上计数
TIM_TimebaseStructure.TIM_RepetitionCounter = 0; //高级定时器选项，普通定时器忽略即可

TIM_TimebaseInit(TIM2 &TIM_TimebaseStructure);// 初始化定时器

//初始化定时器通道：

中断函数：

void TIM2_IRQHandler(void)   //PA1
{
if(TIM_GetITStatus(TIM2TIM_IT_CC2) == SET)
{
TIM_ClearITPendingBit(TIM2TIM_IT_CC2);
i ++;
if(i == 2)
{
i = 0;
TIM2->ARR=1000;
TIM_SetCompare2(TIM250);  
}
}

}

void TIM3_IRQHandler(void) //PA6
{
if(TIM_GetITStatus(TIM3TIM_IT_CC1) == SET)
{
TIM_ClearITPendingBit(TIM2TIM_IT_CC1);
i ++;
if(i == 2)
{
i = 0;
TIM3->ARR=3000; //设置重装载值  改变这个可以改变频率
TIM_SetCompare1(TIM320);  //设置比较值
} 
}
}
