 Unless I cannot see the forest for the trees, the prescale setting is not there.

 

 /** Common config
  */
  hadc3.Instance = ADC3;
  hadc3.Init.Resolution = ADC_RESOLUTION_16B;
  hadc3.Init.ScanConvMode = ADC_SCAN_ENABLE;
  hadc3.Init.EOCSelection = ADC_EOC_SEQ_CONV;
  hadc3.Init.LowPowerAutoWait = DISABLE;
  hadc3.Init.ContinuousConvMode = DISABLE;
  hadc3.Init.NbrOfConversion = 3;
  hadc3.Init.DiscontinuousConvMode = DISABLE;
  hadc3.Init.ExternalTrigConv = ADC_SOFTWARE_START;
  hadc3.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
  hadc3.Init.ConversionDataManagement = ADC_CONVERSIONDATA_DMA_CIRCULAR;
  hadc3.Init.Overrun = ADC_OVR_DATA_OVERWRITTEN;
  hadc3.Init.LeftBitShift = ADC_LEFTBITSHIFT_NONE;
  hadc3.Init.OversamplingMode = DISABLE;
  if (HAL_ADC_Init(&hadc3) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel
  */
  sConfig.Channel = ADC_CHANNEL_TEMPSENSOR;
  sConfig.Rank = ADC_REGULAR_RANK_1;
  sConfig.SamplingTime = ADC_SAMPLETIME_810CYCLES_5;
  sConfig.SingleDiff = ADC_SINGLE_ENDED;
  sConfig.OffsetNumber = ADC_OFFSET_NONE;
  sConfig.Offset = 0;
  sConfig.OffsetSignedSaturation = DISABLE;
  if (HAL_ADC_ConfigChannel(&hadc3, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel
  */
  sConfig.Channel = ADC_CHANNEL_VBAT;
  sConfig.Rank = ADC_REGULAR_RANK_2;
  if (HAL_ADC_ConfigChannel(&hadc3, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel
  */
  sConfig.Channel = ADC_CHANNEL_VREFINT;
  sConfig.Rank = ADC_REGULAR_RANK_3;
  if (HAL_ADC_ConfigChannel(&hadc3, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

 

 

So I added to the user section like so:

 

static void MX_ADC3_Init(void)
{

  /* USER CODE BEGIN ADC3_Init 0 */

  /* USER CODE END ADC3_Init 0 */

  ADC_ChannelConfTypeDef sConfig = {0};

  /* USER CODE BEGIN ADC3_Init 1 */
  hadc3.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV2;
  /* USER CODE END ADC3_Init 1 */

 

Does it show up somewhere else?

Or is this a bug in the CubeMX code?

Or solved by the latest rev?

Hello,

You need to provide the MCU part number or at least attach the ioc file.

Why are you not using the latest version 6.11?

I am in the middle of development and as a rule I never jump to a new revision of the tools unless I am specifically fixing something in the current project where the current tool is the problem.

I must agree with that.

Need to check and get back to you as soon as possible.
