+  * @brief   This file provides firmware functions to manage the following 
+  *          functionalities of the ADC extension peripheral:
+  *           + Extended features functions
+  *

+  ==============================================================================
+                    ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
+       (##) Enable the ADC interface clock using __ADC_CLK_ENABLE()
+       (##) ADC pins configuration
+             (+++) Enable the clock for the ADC GPIOs using the following function:
+                   __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 __DMAx_CLK_ENABLE()
+             (++) Configure and enable two DMA streams stream for managing data
+                 transfer from peripheral to memory (output stream)
+             (++) Associate the initilalized DMA handle to the CRYP 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 mode of operations 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 transfered 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 transfered at each end of conversion           
+       (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue() function.
