  ==============================================================================
                    ##### ADC specific features #####
  ==============================================================================
  [..] 
  (#) Interrupt generation at the end of injected conversion and in case of 
      injected queues overflow.
  
  (#) External trigger (timer or EXTI) with configurable polarity for  
      injected groups.

  (#) Multimode Dual mode when multimode feature is available.
  
  (#) Configurable DMA data storage in Multimode Dual mode.
  
  (#) Configurable delay between conversions in Dual interleaved mode.
  
  (#) ADC calibration.

  (#) ADC channels selectable single/differential input.

  (#) ADC Injected sequencer&channels configuration context queue.

  (#) ADC offset on injected groups.
  
  (#) ADC oversampling.


                     ##### How to use this driver #####
  ==============================================================================
    [..]
  
     (#) Configure the ADC parameters (conversion resolution, data alignment,  
         continuous mode, ...) using the HAL_ADC_Init() function.

     (#) Activate the ADC peripheral using one of the start functions: 
         HAL_ADCEx_InjectedStart(), HAL_ADCEx_InjectedStart_IT() for injected conversions
         or 
         HAL_ADC_MultiModeStart_DMA() for multimode conversions when multimode
         feature is available.
  
  
     *** Channels to injected group configuration ***
     =============================================    
     [..]
       (+) To configure the ADC Injected channels group features, use 
           HAL_ADCEx_InjectedConfigChannel() functions.
       (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue() 
           function.  
            
            
     *** Multimode ADCs configuration (when  multimode feature is available) ***
     ========================================================================
     [..]
       (+) Multimode feature is available and applicable to Master and
           Slave ADCs.
       (+) Refer to "Channels to regular group configuration" description to  
           configure the Master and Slave regular groups.        
       (+) Select the Multi mode ADC  features (dual mode
           simultaneous, interleaved, ...) and configure the DMA mode using 
           HAL_ADCEx_MultiModeConfigChannel() functions. 
       (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue()
           function.
