  ==============================================================================
                             ##### How to use this driver #####
  ==============================================================================
    [..]
    (#) select the ADC clock using the function RCC_ADCCLKConfig()
    (#) Enable the ADC interface clock using RCC_AHBPeriphClockCmd();
    (#) ADC pins configuration
        (++) Enable the clock for the ADC GPIOs using the following function:
             RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOx, ENABLE);
        (++) Configure these ADC pins in analog mode using GPIO_Init();
    (#) Configure the ADC conversion resolution, data alignment, external
        trigger and edge, sequencer lenght and Enable/Disable the continuous mode
        using the ADC_Init() function.
    (#) Activate the ADC peripheral using ADC_Cmd() function.

    *** ADC channels group configuration ***
    ========================================    
    [..] 
    (+) To configure the ADC channels features, use ADC_Init(), ADC_InjectedInit()
        and/or ADC_RegularChannelConfig() functions.
    (+) To activate the continuous mode, use the ADC_ContinuousModeCmd()
        function.
    (+) To activate the Discontinuous mode, use the ADC_DiscModeCmd() functions. 
    (+) To activate the overrun mode, use the ADC_OverrunModeCmd() functions.
    (+) To activate the calibration mode, use the ADC_StartCalibration() functions.
    (+) To read the ADC converted values, use the ADC_GetConversionValue()
        function.

    *** DMA for ADC channels features configuration ***
    ===================================================     
    [..] 
    (+) To enable the DMA mode for ADC channels group, use the ADC_DMACmd() function.
    (+) To configure the DMA transfer request, use ADC_DMAConfig() function.
