Stm32F4 ADC模拟看门狗中断不工作

Question

目前我正在开发ADC模拟看门狗，我想为模拟看门狗写一个中断代码。我通过stm32f4xx的参考手册调整了模拟看门狗，并启动了带有dma的ADC和模拟看门狗定时器进行中断。但是当ırun代码中断不起作用时。问题出在哪里？我的ADC和DMA配置

void adc_ayar()
{
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1,ENABLE);

ADC_InitStruct.ADC_Resolution=ADC_Resolution_12b;
ADC_InitStruct.ADC_ScanConvMode=ENABLE;
ADC_InitStruct.ADC_ExternalTrigConvEdge=ADC_ExternalTrigConvEdge_None;
ADC_InitStruct.ADC_ExternalTrigConv=0;
ADC_InitStruct.ADC_DataAlign=ADC_DataAlign_Right;
ADC_InitStruct.ADC_ContinuousConvMode=ENABLE;
ADC_InitStruct.ADC_NbrOfConversion=bufferlength;

ADC_Init(ADC1,&ADC_InitStruct);

ADC_CommonInitStruct.ADC_DMAAccessMode=ADC_DMAAccessMode_Disabled;
ADC_CommonInitStruct.ADC_Mode=ADC_Mode_Independent;
ADC_CommonInitStruct.ADC_Prescaler=ADC_Prescaler_Div4;
ADC_CommonInitStruct.ADC_TwoSamplingDelay=ADC_TwoSamplingDelay_20Cycles;

ADC_CommonInit(&ADC_CommonInitStruct);
ADC_Init(ADC1,&ADC_InitStruct);

ADC_ITConfig(ADC1,ADC_IT_AWD,ENABLE);
ADC_Cmd(ADC1,ENABLE);

ADC_DMACmd(ADC1,ENABLE);
ADC_DMARequestAfterLastTransferCmd(ADC1,ENABLE);

ADC1->CR1|=1<<6|1<<23;
ADC_AnalogWatchdogSingleChannelConfig(ADC1,ADC_Channel_0);
ADC_AnalogWatchdogThresholdsConfig(ADC1,2500,300);
ADC_AnalogWatchdogCmd(ADC1,ADC_AnalogWatchdog_SingleRegEnable);

ADC_RegularChannelConfig(ADC1,ADC_Channel_0,1,ADC_SampleTime_3Cycles);

ADC_ITConfig(ADC1,ADC_IT_AWD,ENABLE);
}
void dma_ayar()
{
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
DMA_DeInit(DMA2_Stream0);

DMA_InitStruct.DMA_Channel=DMA_Channel_0;
DMA_InitStruct.DMA_Priority=DMA_Priority_VeryHigh;
DMA_InitStruct.DMA_DIR=DMA_DIR_PeripheralToMemory;
DMA_InitStruct.DMA_PeripheralBaseAddr=(uint32_t) & ADC1->DR;
DMA_InitStruct.DMA_Memory0BaseAddr=(uint32_t) & adc_value;
DMA_InitStruct.DMA_BufferSize=2;
DMA_InitStruct.DMA_FIFOMode=DMA_FIFOMode_Enable;
DMA_InitStruct.DMA_FIFOThreshold=DMA_FIFOThreshold_Full;
DMA_InitStruct.DMA_MemoryBurst=DMA_MemoryBurst_Single;
DMA_InitStruct.DMA_PeripheralBurst=DMA_PeripheralBurst_Single;
DMA_InitStruct.DMA_Mode=DMA_Mode_Circular;
DMA_InitStruct.DMA_MemoryDataSize=DMA_MemoryDataSize_HalfWord;
DMA_InitStruct.DMA_PeripheralDataSize=DMA_PeripheralDataSize_HalfWord;
DMA_InitStruct.DMA_MemoryInc=DMA_MemoryInc_Enable;
DMA_InitStruct.DMA_PeripheralInc=DMA_PeripheralInc_Disable;

DMA_Init(DMA2_Stream0,&DMA_InitStruct);

DMA_Cmd(DMA2_Stream0,ENABLE);
}

ADC中断代码

void ADC_IRQHandler()
{
if(ADC_GetITStatus(ADC1,ADC_IT_AWD))
{
sayac++;
GPIO_ToggleBits(GPIOD,GPIO_Pin_12|GPIO_Pin_13);

ADC_ClearITPendingBit(ADC1,ADC_IT_AWD);
}
}

如果我很清楚你想做什么，你应该使用

void HAL_ADC_LevelOutOfWindowCallback(ADC_HandleTypeDef *hadc)

而不是

void ADC_IRQHandler()
