- * peripheral:
- * + Initialization and de-initialization functions
- * ++ Initialization and Configuration of ADC
- * + Operation functions
- * ++ Start, stop, get result of conversions of regular
- * group, using 3 possible modes: polling, interruption or DMA.
- * + Control functions
- * ++ Analog Watchdog configuration
- * ++ Channels configuration on regular group

- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Activate the ADC peripheral using one of the start functions:
- HAL_ADCEx_InjectedStart(), HAL_ADCEx_InjectedStart_IT().
-
- *** Channels configuration to injected group ***
- ================================================
- [..]
- (+) To configure the ADC Injected channels group features, use
- HAL_ADCEx_InjectedConfigChannel() functions.
- (+) To activate the continuous mode, use the HAL_ADC_Init() function.
- (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue()
- function.
