+ * @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.
