ADC Initialization Function Generated From IOC

[mccabehm]

STM32CubeIDE 1.15.1, Windows, STM32H563 MCU

When MX_ADC2_Init() generated by saving IOC file I get the wrong sampling time and rank for Vddcore. The IOC file shows 640.5 cycles and rank 3 but MX_ADC2_Init() shows 2.5 cycles and rank 1:

/**
  * @brief ADC2 Initialization Function
  *  None
  * @retval None
  */
static void MX_ADC2_Init(void)
{

  /* USER CODE BEGIN ADC2_Init 0 */

  /* USER CODE END ADC2_Init 0 */

  ADC_ChannelConfTypeDef sConfig = {0};

  /* USER CODE BEGIN ADC2_Init 1 */

  /* USER CODE END ADC2_Init 1 */

  /** Common config

  hadc2.Instance = ADC2;
  hadc2.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV16;
  hadc2.Init.Resolution = ADC_RESOLUTION_12B;

  hadc2.Init.Oversampling.TriggeredMode = ADC_TRIGGEREDMODE_SINGLE_TRIGGER;
  hadc2.Init.Oversampling.OversamplingStopReset = ADC_REGOVERSAMPLING_CONTINUED_MODE;
  if (HAL_ADC_Init(&hadc2) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel

  sConfig.Channel = ADC_CHANNEL_VCORE;
  sConfig.Rank = ADC_REGULAR_RANK_1;

  sConfig.Offset = 0;
  if (HAL_ADC_ConfigChannel(&hadc2, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  sConfig.Channel = ADC_CHANNEL_3;
  sConfig.SamplingTime = ADC_SAMPLETIME_640CYCLES_5;
  if (HAL_ADC_ConfigChannel(&hadc2, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel

  sConfig.Channel = ADC_CHANNEL_VBAT;
  sConfig.Rank = ADC_REGULAR_RANK_2;
  if (HAL_ADC_ConfigChannel(&hadc2, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure Regular Channel

  sConfig.Channel = ADC_CHANNEL_VCORE;

  {
    Error_Handler();
  }

  /* USER CODE END ADC2_Init 2 */

}

Compare with IOC view...

Is there something special about Vddcore?

Hello @mccabehm 

Thank you for reporting this issue. I've been able to confirm it and I've reported to the concerned team for correction (under internal ticket number 184962).

Best Regards.

Hello @mccabehm 

This behavior has been solved on the last version of the STM32CubeMX V6.13.0.

Best Regards.
