                     ##### How to use this driver #####
 ===============================================================================
    [..]
    (#) Enable the ADC interface clock using 
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADCx, ENABLE); 
       
    (#) ADC pins configuration
         (++) Enable the clock for the ADC GPIOs using the following function:
             RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);   
         (++) Configure these ADC pins in analog mode using GPIO_Init();  
  
     (#) Configure the ADC Prescaler, conversion resolution and data 
         alignment using the ADC_Init() function.
     (#) Activate the ADC peripheral using ADC_Cmd() function.
  
     *** Regular channels group configuration ***
     ============================================
     [..]    
       (+) To configure the ADC regular channels group features, use 
           ADC_Init() and ADC_RegularChannelConfig() functions.
       (+) To activate the continuous mode, use the ADC_continuousModeCmd()
           function.
       (+) To configurate and activate the Discontinuous mode, use the 
           ADC_DiscModeChannelCountConfig() and ADC_DiscModeCmd() functions.
       (+) To read the ADC converted values, use the ADC_GetConversionValue()
           function.
  
     *** Multi mode ADCs Regular channels configuration ***
     ======================================================
     [..]
       (+) Refer to "Regular channels group configuration" description to
           configure the ADC1, ADC2 and ADC3 regular channels.        
       (+) Select the Multi mode ADC regular channels features (dual or 
           triple mode) using ADC_CommonInit() function and configure 
           the DMA mode using ADC_MultiModeDMARequestAfterLastTransferCmd() 
           functions.        
       (+) Read the ADCs converted values using the 
           ADC_GetMultiModeConversionValue() function.
  
     *** DMA for Regular channels group features configuration ***
     ============================================================= 
     [..]
       (+) To enable the DMA mode for regular channels group, use the 
           ADC_DMACmd() function.
       (+) To enable the generation of DMA requests continuously at the end
           of the last DMA transfer, use the ADC_DMARequestAfterLastTransferCmd() 
           function.
  
     *** Injected channels group configuration ***
     =============================================    
     [..]
       (+) To configure the ADC Injected channels group features, use 
           ADC_InjectedChannelConfig() and  ADC_InjectedSequencerLengthConfig()
           functions.
       (+) To activate the continuous mode, use the ADC_continuousModeCmd()
           function.
       (+) To activate the Injected Discontinuous mode, use the 
           ADC_InjectedDiscModeCmd() function.  
       (+) To activate the AutoInjected mode, use the ADC_AutoInjectedConvCmd() 
           function.        
       (+) To read the ADC converted values, use the ADC_GetInjectedConversionValue() 
           function.
