  * @brief  Structure definition of ADC and regular group initialization 
  * @note   Parameters of this structure are shared within 2 scopes:
  *          - Scope entire ADC (affects regular and injected groups): ClockPrescaler, Resolution, ScanConvMode, DataAlign, ScanConvMode, EOCSelection, LowPowerAutoWait, LowPowerAutoPowerOff, ChannelsBank.
  *          - Scope regular group: ContinuousConvMode, NbrOfConversion, DiscontinuousConvMode, NbrOfDiscConversion, ExternalTrigConvEdge, ExternalTrigConv.
  * @note   The setting of these parameters with function HAL_ADC_Init() is conditioned to ADC state.
  *         ADC state can be either:
  *          - For all parameters: ADC disabled
  *          - For all parameters except 'Resolution', 'ScanConvMode', 'DiscontinuousConvMode', 'NbrOfDiscConversion' : ADC enabled without conversion on going on regular group.
  *          - For parameters 'ExternalTrigConv' and 'ExternalTrigConvEdge': ADC enabled, even with conversion on going.
  *         If ADC is not in the appropriate state to modify some parameters, these parameters setting is bypassed
  *         without error reporting (as it can be the expected behaviour in case of intended action to update another parameter (which fulfills the ADC state condition) on the fly).

                                       Note: If overrun feature is intended to be used, use ADC in mode 'interruption' (function HAL_ADC_Start_IT() ) with parameter EOCSelection set to end of each conversion or in mode 'transfer by DMA' (function HAL_ADC_Start_DMA()).
