STM32f103的利用DMA进行ADC多通道输出的数据乱了，真的不清楚

程序如下：
#define ADC1_DR_Address    ((u32)0x4001244C)


void  ADC_DMAconfiguration()
{
          ADC_InitTypeDef ADC_InitStructure;
    DMA_InitTypeDef DMA_InitStructure;
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1 , ENABLE);
          RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);        
        //  RCC_ADCCLKConfig(RCC_PCLK2_Div6);
       
       
       
    DMA_DeInit(DMA1_Channel1);
    DMA_InitStructure.DMA_PeripheralBaseAddr = ADC1_DR_Address;
    DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t)&ADCConvertedValue;
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
    DMA_InitStructure.DMA_BufferSize =2;
    DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
    DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
    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);
    DMA_Cmd(DMA1_Channel1, ENABLE);


          ADC_DeInit(ADC1);
    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 =2;
    ADC_Init(ADC1, &ADC_InitStructure);
          ADC_RegularChannelConfig(ADC1, ADC_Channel_6,1, ADC_SampleTime_239Cycles5);
                ADC_RegularChannelConfig(ADC1, ADC_Channel_7,2, ADC_SampleTime_239Cycles5);
    ADC_DMACmd(ADC1, ENABLE);
    ADC_Cmd(ADC1, ENABLE);
    ADC_ResetCalibration(ADC1);
    while(ADC_GetResetCalibrationStatus(ADC1));
    ADC_StartCalibration(ADC1);
    while(ADC_GetCalibrationStatus(ADC1));
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);
}


int  read()
{

  result_CV=ADCConvertedValue[0];
        result_cv=(unsigned int)(((unsigned long)result_CV)*3300/4095) ;
        result_CC=ADCConvertedValue[1];
  result_cc=(unsigned int)(((unsigned long)result_CC)*3300/4095) ;       
         
}
