使用STM32L073RZ除錯兩路AD電壓訊號採集，剛開始用DMA方式，發現開啟DMA轉換USB虛擬串列埠無法識別。現在想不通過DMA方式來進行兩路AD電壓訊號採集。單路讀取方法為
aADCxConvertedData = HAL_ADC_GetValue(&hadc);
兩路AD電壓訊號採集（非DMA方式）為：使用非連續轉換，每次配置某個通道 、然後啟動ADC，讀取資料；再開啟另一通道，啟動ADC，讀取資料。
部分程式為：

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();
  }
