  * @brief  Initializes 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
  *         depending on possible clock sources: AHB clock or PLL clock.
  *         See commented example code below that can be copied and uncommented 
  *         into HAL_ADC_MspInit().
  * @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 by 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   For devices with several ADCs: parameters related to common ADC 
  *         registers (ADC clock mode) are set only if all ADCs sharing the
  *         same common group are disabled.
  *         If this is not the case, these common parameters setting are  
  *         bypassed without error reporting: it can be the intended behaviour in
  *         case of update of a parameter of ADC_InitTypeDef on the fly,
  *         without  disabling the other ADCs sharing the same common group.

  * @brief  Initializes 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
  *         (clock source APB2).
  *         See commented example code below that can be copied and uncommented 
  *         into HAL_ADC_MspInit().
  * @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".

/**
  * @brief  Configures 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, following 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 recommended sampling time is at least:
  *          - For devices STM32F37x: 17.1us for temperature sensor
  *          - For the other STM32F3 devices: 2.2us for each of channels 
  *            Vbat/VrefInt/TempSensor.
  *         These internal paths can be 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 configured 
  * consecutively for the same ADC instance. Therefore, Number of calls of 
  * HAL_ADCEx_InjectedConfigChannel() must correspond to value of parameter 
  * InjectedNbrOfConversion for each context.
  *  - Example 1: If 1 context intended to be used (or not use of this feature: 
  *    QueueInjectedContext=DISABLE) and usage of the 3 first injected ranks 
  *    (InjectedNbrOfConversion=3), HAL_ADCEx_InjectedConfigChannel() must be  
  *    called once for each channel (3 times) before launching a conversion.   
  *    This function must not be called to configure the 4th injected channel:   
  *    it would start a new context into context queue.
  *  - Example 2: If 2 contexts intended to be used and usage of the 3 first 
  *    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. 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.

  * @note   In case of usage of internal measurement channels:
