目的：通过DMA实现ADC1的通道1、2、3电压采集，对三个通道连续采集10次，采集的数据储存于一个二维数组中u16 uhADCxConvertedValue[10][3]。
现象：实际采集时，数组的前4个元素仅更新一次后不再更新，后面的数据可以正常更新，仿真结果如图：
   DMA设置的memaddr跟数组地址是一致的，但是前4个数据不会更新。如果用一维数组u16 uhADCxConvertedValue[3]储存三个通道的数据就完全不更新了。贴出代码，求大佬们解答。

ADC配置代码如下：

/* ADC handler declaration */
ADC_HandleTypeDef    AdcHandle;
/* Variable used to get converted value */
u16 uhADCxConvertedValue[10][3] = {0};

void bsp_ADC_Init(void)
{
        ADC_ChannelConfTypeDef sConfig;
       
        /*##-1- Configure the ADC peripheral #######################################*/
        AdcHandle.Instance                           = ADC1;
        AdcHandle.Init.ClockPrescaler        = ADC_CLOCKPRESCALER_PCLK_DIV4;
        AdcHandle.Init.Resolution            = ADC_RESOLUTION_12B;
        AdcHandle.Init.ScanConvMode          = ENABLE;                        /* Sequencer disabled (ADC conversion on only 1 channel: channel set on rank 1) */
        AdcHandle.Init.ContinuousConvMode    = ENABLE;                        /* Continuous mode disabled to have only 1 conversion at each conversion trig */
        AdcHandle.Init.DiscontinuousConvMode = DISABLE;                       /* Parameter discarded because sequencer is disabled */
        AdcHandle.Init.NbrOfDiscConversion   = 0;
        AdcHandle.Init.ExternalTrigConvEdge  = ADC_EXTERNALTRIGCONVEDGE_NONE;        /* Conversion start trigged at each external event */
        AdcHandle.Init.ExternalTrigConv      = ADC_EXTERNALTRIGCONV_T1_CC1;
        AdcHandle.Init.DataAlign             = ADC_DATAALIGN_RIGHT;
        AdcHandle.Init.NbrOfConversion       = 3;
        AdcHandle.Init.DMAContinuousRequests = ENABLE;
        AdcHandle.Init.EOCSelection          = DISABLE;
       
        HAL_ADC_Init(&AdcHandle);
       
        /*##-2- Configure ADC regular channel ######################################*/
    sConfig.Channel      = ADC_CHANNEL_1;
    sConfig.Rank         = 1;
    sConfig.SamplingTime = ADC_SAMPLETIME_480CYCLES;
    sConfig.Offset       = 0;  
    HAL_ADC_ConfigChannel(&AdcHandle, &sConfig);

    sConfig.SamplingTime = ADC_SAMPLETIME_480CYCLES;
    sConfig.Offset       = 0;
    HAL_ADC_ConfigChannel(&AdcHandle, &sConfig);

    HAL_ADC_Start_DMA(&AdcHandle,(u32*)uhADCxConvertedValue,30);
}
