================================================================================
                      ##### How to use this driver #####
================================================================================
    [..]
    (#) Enable the ADC interface clock using 
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE); 
    (#) 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, scan direction 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() and 
        ADC_ChannelConfig() 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_GetCalibrationFactor() 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_DMARequestModeConfig() function.
