ADCのサンプルコード

ANALOG INPUT：PA.4（ADC_AIN_CHANNEL_X)、PC.4（ADC_AIN_CHANNEL_Y)、PC.5（ADC_AIN_CHANNEL_Z)
DMA1を利用して、X Y Z情報がADC1_DR_AddressからADC_ConvertedValueXに自動保存します。
ADC_ConvertedValueX[0]=X
ADC_ConvertedValueX[1]=Y
ADC_ConvertedValueX[2]=Z

サンプルコードが下記に示す。

void ADC_Configuration(void)
{
ADC_InitTypeDef ADC_InitStructure;
DMA_InitTypeDef DMA_InitStructure;

/* Enable DMA1 clock */
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);

/* Enable ADC1 clock */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

/* DMA1 channel1 configuration ---------------------------------------------*/
DMA_DeInit(DMA1_Channel1);
DMA_InitStructure.DMA_PeripheralBaseAddr = ADC1_DR_Address;
DMA_InitStructure.DMA_MemoryBaseAddr = (u32)&ADC_ConvertedValueX[0];
DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
DMA_InitStructure.DMA_BufferSize = 3;
DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;/*DMA_MemoryInc_Disable;*/
DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
DMA_InitStructure.DMA_Priority = DMA_Priority_High;
DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
DMA_Init(DMA1_Channel1, &DMA_InitStructure);

/* Enable DMA1 channel1 */
DMA_Cmd(DMA1_Channel1, ENABLE);

/* Enable the DMA1 Channel1 Transfer complete interrupt */
DMA_ITConfig(DMA1_Channel1, DMA_IT_TC, ENABLE);

/* ADC1 configuration ------------------------------------------------------*/
ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
ADC_InitStructure.ADC_ScanConvMode = ENABLE;
ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStructure.ADC_NbrOfChannel = 3;
ADC_Init(ADC1, &ADC_InitStructure);

/* ADC1 regular channel configuration */
ADC_RegularChannelConfig(ADC1, ADC_AIN_CHANNEL_X, 1, ADC_SampleTime_55Cycles5);
ADC_RegularChannelConfig(ADC1, ADC_AIN_CHANNEL_Y, 2, ADC_SampleTime_55Cycles5);
ADC_RegularChannelConfig(ADC1, ADC_AIN_CHANNEL_Z, 3, ADC_SampleTime_55Cycles5);

/* Enable ADC1 DMA */
ADC_DMACmd(ADC1, ENABLE);

/* Enable ADC1 */
ADC_Cmd(ADC1, ENABLE);

/* Enable ADC1 reset calibaration register */
ADC_ResetCalibration(ADC1);
/* Check the end of ADC1 reset calibration register */
while(ADC_GetResetCalibrationStatus(ADC1));

/* Start ADC1 calibaration */
ADC_StartCalibration(ADC1);

/* Check the end of ADC1 calibration */
while(ADC_GetCalibrationStatus(ADC1));
}

今、OpenJTAGを使ってデバック環境でX、Y、Z情報をきちんと取りますが、デバッグ以外の場合がDMA１の割り込みを発生しません。
何で？
