Detailed Description

Temperature Sensor, Vrefint and VBAT management functions.

Vbat, Temperature Sensor & Vrefint (Internal Reference Voltage) management function.

and VBAT (Voltage BATtery) management functions

 ===============================================================================
      ##### Temperature Sensor, Vrefint and VBAT management functions #####
 ===============================================================================  
    [..] This section provides functions allowing to enable/ disable the internal 
         connections between the ADC and the Temperature Sensor, the Vrefint and 
         the Vbat sources.
     
    [..] A typical configuration to get the Temperature sensor and Vrefint channels 
         voltages is done following these steps :
      (#) Enable the internal connection of Temperature sensor and Vrefint sources 
          with the ADC channels using ADC_TempSensorVrefintCmd() function. 
      (#) Select the ADC_Channel_TempSensor and/or ADC_Channel_Vrefint using 
          ADC_RegularChannelConfig() or  ADC_InjectedChannelConfig() functions 
      (#) Get the voltage values, using ADC_GetConversionValue() or  
          ADC_GetInjectedConversionValue().

    [..] A typical configuration to get the VBAT channel voltage is done following 
         these steps :
      (#) Enable the internal connection of VBAT source with the ADC channel using 
          ADC_VBATCmd() function. 
      (#) Select the ADC_Channel_Vbat using ADC_RegularChannelConfig() or  
          ADC_InjectedChannelConfig() functions 
      (#) Get the voltage value, using ADC_GetConversionValue() or  
          ADC_GetInjectedConversionValue().

  [..] This section provides a function allowing to enable/ disable the internal 
  connections between the ADC and the Vbat/2, Temperature Sensor and the Vrefint source.

  [..] A typical configuration to get the Temperature sensor and Vrefint channels 
  voltages is done following these steps :
   (#) Enable the internal connection of Vbat/2, Temperature sensor and Vrefint sources 
       with the ADC channels using:
      (++) ADC_TempSensorCmd()  
      (++) ADC_VrefintCmd() 
      (++) ADC_VbatCmd()  

   (#) select the ADC_Channel_TempSensor and/or ADC_Channel_Vrefint and/or ADC_Channel_Vbat using 
      (++) ADC_RegularChannelConfig() or  
      (++) ADC_InjectedInit() functions 

   (#) Get the voltage values, using:
      (++) ADC_GetConversionValue() or  
      (++) ADC_GetInjectedConversionValue().
