              TIM3 Driver: how to use it in Input Capture Mode
       =================================================================== 
       To use the Timer in Input Capture mode, the following steps are mandatory:
       
       1. Enable TIM3 clock using CLK_PeripheralClockConfig(CLK_Peripheral_TIM3, ENABLE) function.
       
       2. Configure the TIM3 pins in input mode by configuring the corresponding GPIO pins
       
       3. Configure the Time base unit as described in the first part of this driver, if needed,
          otherwise the Timer will run with the default configuration:
          - Autoreload value = 0xFFFF
          - Prescaler value = 0x0
          - Counter mode = Up counting
       
       4. Call TIM3_ICInit() to configure the desired channel to measure only 
          frequency or duty cycle of the input signal using the corresponding configuration: 
          - TIM3 Channel: TIM3_Channel
          - TIM3 Input Capture polarity: TIM3_ICPolarity
          - TIM3 Input Capture selection: TIM3_ICSelection
          - TIM3 Input Capture Prescaler: TIM3_ICPSC
          - TIM3 Input Capture filter value
          or,
          Call TIM3_PWMIConfig() to configure the desired channels with the 
          corresponding configuration and to measure the frequency and the duty
          cycle of the input signal.
          
       5. Enable global interrupts or the DMA to read the measured frequency. 
          
       6. Enable the corresponding interrupt (or DMA request) to read the captured value,
          using the function TIM3_ITConfig(TIM3_IT_CCx) (or TIM3_DMACmd(TIM3_DMASource_CCx))
       
       7. Call the TIM3_Cmd(ENABLE) function to enable the TIM3 counter.
       
       8. Use TIM3_GetCapturex() to read the captured value corresponding to
          channel x.
       
       Note1: All other functions can be used separately to modify, if needed,
          a specific feature of the Timer.
