STM32L073RZ进行两路AD电压信号采集(非DMA方式)

使用STM32L073RZ调试两路AD电压信号采集，刚开始用DMA方式，发现开启DMA转换USB虚拟串口无法识别。现在想不通过DMA方式来进行两路AD电压信号采集。单路读取方法为
aADCxConvertedData = HAL_ADC_GetValue(&hadc);
两路AD电压信号采集（非DMA方式）为：使用非连续转换，每次配置某个通道、然后启动ADC，读取数据；再开启另一通道，启动ADC，读取数据。
部分程序为：

static uint16_t   aADCxConvertedData[2];static void MX_ADC_Init(void){  hadc.Instance = ADC1;  hadc.Init.OversamplingMode = DISABLE;  hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV1;  hadc.Init.Resolution = ADC_RESOLUTION_12B;  hadc.Init.SamplingTime = ADC_SAMPLETIME_1CYCLE_5;  hadc.Init.ScanConvMode = ADC_SCAN_DIRECTION_FORWARD;  hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;  hadc.Init.ContinuousConvMode = DISABLE;  hadc.Init.DiscontinuousConvMode = ENABLE;  hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;  hadc.Init.DMAContinuousRequests = DISABLE;  hadc.Init.EOCSelection = ADC_EOC_SINGLE_CONV;  hadc.Init.Overrun = ADC_OVR_DATA_PRESERVED;  hadc.Init.LowPowerAutoWait = DISABLE;  hadc.Init.LowPowerFrequencyMode = DISABLE;  hadc.Init.LowPowerAutoPowerOff = DISABLE;  if (HAL_ADC_Init(&hadc) != HAL_OK)  {    Error_Handler();  }    /**Configure for the selected ADC regular channel to be converted.     *///  sConfig.Channel = ADC_CHANNEL_8;//  sConfig.Rank = ADC_RANK_CHANNEL_NUMBER;//  if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)//  {//    Error_Handler();//  }//    /**Configure for the selected ADC regular channel to be converted. //    *///  sConfig.Channel = ADC_CHANNEL_9;//  if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)//  {//    Error_Handler();//  }}int main(void){  HAL_Init();/* Configure the system clock */  SystemClock_Config();  BSP_LED_Init();  /* Initialize all configured peripherals */  MX_GPIO_Init();  MX_ADC_Init();  while (1)  {     sConfig.Channel = ADC_CHANNEL_8;     sConfig.Rank = ADC_RANK_CHANNEL_NUMBER;    if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)       {        Error_Handler();       }    if (HAL_ADC_Start(&hadc) != HAL_OK)      {        Error_Handler();      }    aADCxConvertedData[0] = HAL_ADC_GetValue(&hadc);   sConfig.Channel = ADC_CHANNEL_9;   if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)      {        Error_Handler();      }   if (HAL_ADC_Start(&hadc) != HAL_OK)     {        Error_Handler();     }                 aADCxConvertedData[1] = HAL_ADC_GetValue(&hadc);  }}
