  *          peripheral:
  *          + Operation functions
  *             ++ Start, stop, get result of conversions of injected
  *                group, using 2 possible modes: polling, interruption.
  *             ++ Calibration
  *               +++ ADC automatic self-calibration
  *               +++ Calibration factors get or set

  * @brief  Configure a channel to be assigned to ADC group injected.
  * @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:
  *         Refer to comments of structure "ADC_InjectionConfTypeDef".
  * @note   In case of usage of internal measurement channels:
  *         Vbat/VrefInt/TempSensor.
  *         These internal paths can be disabled using function
  *         HAL_ADC_DeInit().
  * @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.
