  * @brief   This file provides firmware functions to manage the following

  ==============================================================================
                    ##### How to use this driver #####
  ==============================================================================
    [..]
    (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
       (##) Enable the ADC interface clock using __HAL_RCC_ADC_CLK_ENABLE()
       (##) ADC pins configuration
             (+++) Enable the clock for the ADC GPIOs using the following function:
                   __HAL_RCC_GPIOx_CLK_ENABLE()  
             (+++) Configure these ADC pins in analog mode using HAL_GPIO_Init() 
       (##) In case of using interrupts (e.g. HAL_ADC_Start_IT())
             (+++) Configure the ADC interrupt priority using HAL_NVIC_SetPriority()
             (+++) Enable the ADC IRQ handler using HAL_NVIC_EnableIRQ()
             (+++) In ADC IRQ handler, call HAL_ADC_IRQHandler()
      (##) In case of using DMA to control data transfer (e.g. HAL_ADC_Start_DMA())
             (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE()
             (+++) Configure and enable two DMA streams stream for managing data
                 transfer from peripheral to memory (output stream)
             (+++) Associate the initialized DMA handle to the ADC DMA handle
                 using  __HAL_LINKDMA()
             (+++) Configure the priority and enable the NVIC for the transfer complete
                 interrupt on the two DMA Streams. The output stream should have higher
                 priority than the input stream.                  
     (#) Configure the ADC Prescaler, conversion resolution and data alignment 
         using the HAL_ADC_Init() function. 
  
     (#) Configure the ADC Injected channels group features, use HAL_ADC_Init()
         and HAL_ADC_ConfigChannel() functions.
         
     (#) Three operation modes are available within this driver :     
  
     *** Polling mode IO operation ***
     =================================
     [..]    
       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart() 
       (+) Wait for end of conversion using HAL_ADC_PollForConversion(), at this stage
           user can specify the value of timeout according to his end application      
       (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue() function.
       (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop()
  
     *** Interrupt mode IO operation ***    
     ===================================
     [..]    
       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_IT() 
       (+) Use HAL_ADC_IRQHandler() called under ADC_IRQHandler() Interrupt subroutine
       (+) At ADC end of conversion HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can 
            add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback 
       (+) In case of ADC Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can 
            add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback
       (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_IT()
       
            
     *** DMA mode IO operation ***    
     ==============================
     [..]    
       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_DMA(), at this stage the user specify the length 
           of data to be transferred at each end of conversion 
       (+) At The end of data transfer ba HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can 
            add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback 
       (+) In case of transfer Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can 
            add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback
        (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_DMA()
        
     *** Multi mode ADCs Regular channels configuration ***
     ======================================================
     [..]        
       (+) Select the Multi mode ADC regular channels features (dual or triple mode)  
          and configure the DMA mode using HAL_ADCEx_MultiModeConfigChannel() functions. 
       (+) Start the ADC peripheral using HAL_ADCEx_MultiModeStart_DMA(), at this stage the user specify the length 
           of data to be transferred at each end of conversion           
       (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue() function.
