  * @brief   This file provides firmware functions to manage the following 
  *          functionalities of the Analog to Digital Convertor (ADC)
  *          peripheral:
  *           + Calibration functions
  *             ++ Calibration start-up
  *             ++ Calibration value reading or setting 
  *           + Operation functions
  *             ++ Start, stop, get result of conversions of injected
  *             groups, using 3 possible modes: polling or interruption.
  *             ++ Multimode feature when available
  *           + Control functions
  *             ++ Configure channels on injected group
  *           + State functions
  *             ++ Injected group queues management

   @verbatim           
  ==============================================================================
                    ##### 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.

/**  
  * @brief  Configure the ADC injected group and the selected channel to be linked to the injected group.
  * @note   Possibility to update parameters on the fly:
  *         This function initializes injected group, consecutive calls to this 
  *         function can be used to reconfigure some parameters of structure
  *         "ADC_InjectionConfTypeDef" on the fly, without resetting the ADC.
  *         The setting of these parameters is conditioned to ADC state.
  *         For parameters constraints, see comments of structure 
  *         "ADC_InjectionConfTypeDef".
  * @note   In case of usage of internal measurement channels (Vbat/VrefInt/TempSensor),
  *         The internal paths can be disabled using function HAL_ADC_DeInit().
  * @note   To reset injected sequencer, function HAL_ADCEx_InjectedStop() can
  *         be used.
  * @note   Caution: For Injected Context Queue use, a context must be fully 
  *         defined before start of injected conversion. All channels are configured 
  *         consecutively for the same ADC instance. Therefore, the number of calls to 
  *         HAL_ADCEx_InjectedConfigChannel() must be equal to the value of parameter 
  *         InjectedNbrOfConversion for each context.
  *  - Example 1: If 1 context is intended to be used (or if there is no use of the 
  *    Injected Queue Context feature) and if the context contains 3 injected ranks 
  *    (InjectedNbrOfConversion = 3), HAL_ADCEx_InjectedConfigChannel() must be  
  *    called once for each channel (i.e. 3 times) before starting a conversion.   
  *    This function must not be called to configure a 4th injected channel:   
  *    it would start a new context into context queue.
  *  - Example 2: If 2 contexts are intended to be used and each of them contains 
  *    3 injected ranks (InjectedNbrOfConversion = 3),  
  *    HAL_ADCEx_InjectedConfigChannel() must be called once for each channel and  
  *    for each context (3 channels x 2 contexts = 6 calls). Conversion can  
  *    start once the 1st context is set, that is after the first three 
  *    HAL_ADCEx_InjectedConfigChannel() calls. The 2nd context can be set on the fly.
  * @param  hadc: ADC handle
  * @param  sConfigInjected: Structure of ADC injected group and ADC channel for
  *         injected group.
  * @retval None
