  *          ===================================================================      
  *                                   How to use this driver
  *          ===================================================================      
  *          1. Enable The ADC controller clock using CLK_PeripheralClockConfig() 
  *            function : CLK_PeripheralClockConfig(CLK_Peripheral_ADC1, ENABLE).
  *
  *            2. Configure the ADC Prescaler, conversion resolution and data 
  *              alignment using the ADC_Init() function.
  * 
  *            3. 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 configure and activate the Discontinuous mode, use the 
  *              ADC_DiscModeChannelCountConfig() and ADC_DiscModeCmd() functions.        
  *            - To read the ADC converted values, use the ADC_GetConversionValue()
  *              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.
