                     ##### How to use this driver #####
  ==============================================================================
    [..]

     *** Configuration of top level parameters related to ADC ***
     ============================================================
     [..]

    (#) Enable the ADC interface
        (++) As prerequisite, ADC clock must be configured at RCC top level.

        (++) Two clock settings are mandatory:
             (+++) ADC clock (core clock, also possibly conversion clock).

             (+++) ADC clock (conversions clock).
                   Two possible clock sources: synchronous clock derived from APB clock
                   or asynchronous clock derived from system clock, PLLSAI1 or the PLLSAI2
                   running up to 80MHz.

             (+++) Example:
                   Into HAL_ADC_MspInit() (recommended code location) or with
                   other device clock parameters configuration:
               (+++) __HAL_RCC_ADC_CLK_ENABLE();                  (mandatory)

               RCC_ADCCLKSOURCE_PLL enable:                       (optional: if asynchronous clock selected)
               (+++) RCC_PeriphClkInitTypeDef   RCC_PeriphClkInit;
               (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
               (+++) PeriphClkInit.AdcClockSelection    = RCC_ADCCLKSOURCE_PLL;
               (+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit);

        (++) ADC clock source and clock prescaler are configured at ADC level with
             parameter "ClockPrescaler" using function HAL_ADC_Init().

    (#) ADC pins configuration
         (++) Enable the clock for the ADC GPIOs
              using macro __HAL_RCC_GPIOx_CLK_ENABLE()
         (++) Configure these ADC pins in analog mode
              using function HAL_GPIO_Init()

    (#) Optionally, in case of usage of ADC with interruptions:
         (++) Configure the NVIC for ADC
              using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
         (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
              into the function of corresponding ADC interruption vector
              ADCx_IRQHandler().

    (#) Optionally, in case of usage of DMA:
         (++) Configure the DMA (DMA channel, mode normal or circular, ...)
              using function HAL_DMA_Init().
         (++) Configure the NVIC for DMA
              using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
         (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
              into the function of corresponding DMA interruption vector
              DMAx_Channelx_IRQHandler().

     *** Configuration of ADC, group regular, channels parameters ***
     ================================================================
     [..]

    (#) Configure the ADC parameters (resolution, data alignment, ...)
        and regular group parameters (conversion trigger, sequencer, ...)
        using function HAL_ADC_Init().

    (#) Configure the channels for regular group parameters (channel number,
        channel rank into sequencer, ..., into regular group)
        using function HAL_ADC_ConfigChannel().

    (#) Optionally, configure the analog watchdog parameters (channels
        monitored, thresholds, ...)
        using function HAL_ADC_AnalogWDGConfig().

     *** Execution of ADC conversions ***
     ====================================
     [..]

    (#) Optionally, perform an automatic ADC calibration to improve the
        conversion accuracy
        using function HAL_ADCEx_Calibration_Start().

    (#) ADC driver can be used among three modes: polling, interruption,
        transfer by DMA.

        (++) ADC conversion by polling:
          (+++) Activate the ADC peripheral and start conversions
                using function HAL_ADC_Start()
          (+++) Wait for ADC conversion completion
                using function HAL_ADC_PollForConversion()
          (+++) Retrieve conversion results
                using function HAL_ADC_GetValue()
          (+++) Stop conversion and disable the ADC peripheral
                using function HAL_ADC_Stop()

        (++) ADC conversion by interruption:
          (+++) Activate the ADC peripheral and start conversions
                using function HAL_ADC_Start_IT()
          (+++) Wait for ADC conversion completion by call of function
                HAL_ADC_ConvCpltCallback()
                (this function must be implemented in user program)
          (+++) Retrieve conversion results
                using function HAL_ADC_GetValue()
          (+++) Stop conversion and disable the ADC peripheral
                using function HAL_ADC_Stop_IT()

        (++) ADC conversion with transfer by DMA:
          (+++) Activate the ADC peripheral and start conversions
                using function HAL_ADC_Start_DMA()
          (+++) Wait for ADC conversion completion by call of function
                HAL_ADC_ConvCpltCallback() or HAL_ADC_ConvHalfCpltCallback()
                (these functions must be implemented in user program)
          (+++) Conversion results are automatically transferred by DMA into
                destination variable address.
          (+++) Stop conversion and disable the ADC peripheral
                using function HAL_ADC_Stop_DMA()

     [..]

    (@) Callback functions must be implemented in user program:
      (+@) HAL_ADC_ErrorCallback()
      (+@) HAL_ADC_LevelOutOfWindowCallback() (callback of analog watchdog)
      (+@) HAL_ADC_ConvCpltCallback()
      (+@) HAL_ADC_ConvHalfCpltCallback

     *** Deinitialization of ADC ***
     ============================================================
     [..]

    (#) Disable the ADC interface
      (++) ADC clock can be hard reset and disabled at RCC top level.
        (++) Hard reset of ADC peripherals
             using macro __ADCx_FORCE_RESET(), __ADCx_RELEASE_RESET().
        (++) ADC clock disable
             using the equivalent macro/functions as configuration step.
             (+++) Example:
                   Into HAL_ADC_MspDeInit() (recommended code location) or with
                   other device clock parameters configuration:
               (+++) RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14;
               (+++) RCC_OscInitStructure.HSI14State = RCC_HSI14_OFF; (if not used for system clock)
               (+++) HAL_RCC_OscConfig(&RCC_OscInitStructure);

    (#) ADC pins configuration
         (++) Disable the clock for the ADC GPIOs
              using macro __HAL_RCC_GPIOx_CLK_DISABLE()

    (#) Optionally, in case of usage of ADC with interruptions:
         (++) Disable the NVIC for ADC
              using function HAL_NVIC_EnableIRQ(ADCx_IRQn)

    (#) Optionally, in case of usage of DMA:
         (++) Deinitialize the DMA
              using function HAL_DMA_Init().
         (++) Disable the NVIC for DMA
              using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)

    [..]

    *** Callback registration ***
    =============================================
    [..]

     The compilation flag USE_HAL_ADC_REGISTER_CALLBACKS, when set to 1,
     allows the user to configure dynamically the driver callbacks.
     Use Functions HAL_ADC_RegisterCallback()
     to register an interrupt callback.
    [..]

     Function HAL_ADC_RegisterCallback() allows to register following callbacks:
       (+) ConvCpltCallback               : ADC conversion complete callback
       (+) ConvHalfCpltCallback           : ADC conversion DMA half-transfer callback
       (+) LevelOutOfWindowCallback       : ADC analog watchdog 1 callback
       (+) ErrorCallback                  : ADC error callback
       (+) InjectedConvCpltCallback       : ADC group injected conversion complete callback
       (+) InjectedQueueOverflowCallback  : ADC group injected context queue overflow callback
       (+) LevelOutOfWindow2Callback      : ADC analog watchdog 2 callback
       (+) LevelOutOfWindow3Callback      : ADC analog watchdog 3 callback
       (+) EndOfSamplingCallback          : ADC end of sampling callback
       (+) MspInitCallback                : ADC Msp Init callback
       (+) MspDeInitCallback              : ADC Msp DeInit callback
     This function takes as parameters the HAL peripheral handle, the Callback ID
     and a pointer to the user callback function.
    [..]

     Use function HAL_ADC_UnRegisterCallback to reset a callback to the default
     weak function.
    [..]

     HAL_ADC_UnRegisterCallback takes as parameters the HAL peripheral handle,
     and the Callback ID.
     This function allows to reset following callbacks:
       (+) ConvCpltCallback               : ADC conversion complete callback
       (+) ConvHalfCpltCallback           : ADC conversion DMA half-transfer callback
       (+) LevelOutOfWindowCallback       : ADC analog watchdog 1 callback
       (+) ErrorCallback                  : ADC error callback
       (+) InjectedConvCpltCallback       : ADC group injected conversion complete callback
       (+) InjectedQueueOverflowCallback  : ADC group injected context queue overflow callback
       (+) LevelOutOfWindow2Callback      : ADC analog watchdog 2 callback
       (+) LevelOutOfWindow3Callback      : ADC analog watchdog 3 callback
       (+) EndOfSamplingCallback          : ADC end of sampling callback
       (+) MspInitCallback                : ADC Msp Init callback
       (+) MspDeInitCallback              : ADC Msp DeInit callback
     [..]

     By default, after the HAL_ADC_Init() and when the state is HAL_ADC_STATE_RESET
     all callbacks are set to the corresponding weak functions:
     examples HAL_ADC_ConvCpltCallback(), HAL_ADC_ErrorCallback().
     Exception done for MspInit and MspDeInit functions that are
     reset to the legacy weak functions in the HAL_ADC_Init()/ HAL_ADC_DeInit() only when
     these callbacks are null (not registered beforehand).
    [..]

     If MspInit or MspDeInit are not null, the HAL_ADC_Init()/ HAL_ADC_DeInit()
     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
     [..]

     Callbacks can be registered/unregistered in HAL_ADC_STATE_READY state only.
     Exception done MspInit/MspDeInit functions that can be registered/unregistered
     in HAL_ADC_STATE_READY or HAL_ADC_STATE_RESET state,
     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
    [..]

     Then, the user first registers the MspInit/MspDeInit user callbacks
     using HAL_ADC_RegisterCallback() before calling HAL_ADC_DeInit()
     or HAL_ADC_Init() function.
     [..]

     When the compilation flag USE_HAL_ADC_REGISTER_CALLBACKS is set to 0 or
     not defined, the callback registration feature is not available and all callbacks
     are set to the corresponding weak functions.

/**
  * @brief  Initialize the ADC peripheral and regular group according to
  *         parameters specified in structure "ADC_InitTypeDef".
  * @note   As prerequisite, ADC clock must be configured at RCC top level
  *         (refer to description of RCC configuration for ADC
  *         in header of this file).
  * @note   Possibility to update parameters on the fly:
  *         This function initializes the ADC MSP (HAL_ADC_MspInit()) only when
  *         coming from ADC state reset. Following calls to this function can
  *         be used to reconfigure some parameters of ADC_InitTypeDef
  *         structure on the fly, without modifying MSP configuration. If ADC
  *         MSP has to be modified again, HAL_ADC_DeInit() must be called
  *         before HAL_ADC_Init().
  *         The setting of these parameters is conditioned to ADC state.
  *         For parameters constraints, see comments of structure
  *         "ADC_InitTypeDef".
  * @note   This function configures the ADC within 2 scopes: scope of entire
  *         ADC and scope of regular group. For parameters details, see comments
  *         of structure "ADC_InitTypeDef".
  * @note   Parameters related to common ADC registers (ADC clock mode) are set
  *         only if all ADCs are disabled.
  *         If this is not the case, these common parameters setting are
  *         bypassed without error reporting: it can be the intended behaviour in
