Detailed Description

Channels Configuration functions.

 ===============================================================================
                      Channels Configuration functions
 ===============================================================================  
  This section provides functions allowing to:
   - Enable or disable the ADC channel using ADC_ChannelCmd() function,
   - Configure the channels sampling times using ADC_SamplingTimeConfig() 
     function.
     Note: there are 2 sampling times configuration values : 
            - 1st Group value : for channels 0..23  
            - 2nd Group value : for channels 24..27 (depending on the MCU 
              package density) and Temperature Sensor and Vrefint channels. 
   - Configure the channels Schmitt Trigger for each channel using 
     ADC_SchmittTriggerConfig() function.
   - Get the current ADC conversion value.
