+  ======================================================== 
+  [..] 
+  To use the Timer in Output Compare mode, the following steps are mandatory:

+       (#) Enable TIM clock using RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function
+       
+       (#) Configure the TIM pins by configuring the corresponding GPIO pins
+       
+       (#) Configure the Time base unit as described in the first part of this driver, 
+           if needed, else the Timer will run with the default configuration:
+           (++) Autoreload value = 0xFFFF
+           (++) Prescaler value = 0x0000
+           (++) Counter mode = Up counting
+           (++) Clock Division = TIM_CKD_DIV1   
+       (#) Fill the TIM_OCInitStruct with the desired parameters including:
+           (++) The TIM Output Compare mode: TIM_OCMode
+           (++) TIM Output State: TIM_OutputState
+           (++) TIM Pulse value: TIM_Pulse
+           (++) TIM Output Compare Polarity : TIM_OCPolarity
+       
+       (#) Call TIM_OCxInit(TIMx, &TIM_OCInitStruct) to configure the desired channel with the 
+           corresponding configuration
+       
+       (#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
+ [..]      
+       (@) All other functions can be used separately to modify, if needed,
+           a specific feature of the Timer. 
+          
+       (@) In case of PWM mode, this function is mandatory:
+           TIM_OCxPreloadConfig(TIMx, TIM_OCPreload_ENABLE); 
+              
+       (@) If the corresponding interrupt or DMA request are needed, the user should:
+                (#@) Enable the NVIC (or the DMA) to use the TIM interrupts (or DMA requests). 
+                (#@) Enable the corresponding interrupt (or DMA request) using the function

+  *** TIM Driver: how to use it in Input Capture Mode ***
+  =======================================================
+  [..] 
+  To use the Timer in Input Capture mode, the following steps are mandatory:
+       
+      (#) Enable TIM clock using RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function
+       
+      (#) Configure the TIM pins by configuring the corresponding GPIO pins
+       
+      (#) Configure the Time base unit as described in the first part of this driver,
+          if needed, else the Timer will run with the default configuration:
+          (++) Autoreload value = 0xFFFF
+          (++) Prescaler value = 0x0000
+          (++) Counter mode = Up counting
+          (++) Clock Division = TIM_CKD_DIV1
+          
+      (#) Fill the TIM_ICInitStruct with the desired parameters including:
+          (++) TIM Channel: TIM_Channel
+          (++) TIM Input Capture polarity: TIM_ICPolarity
+          (++) TIM Input Capture selection: TIM_ICSelection
+          (++) TIM Input Capture Prescaler: TIM_ICPrescaler
+          (++) TIM Input CApture filter value: TIM_ICFilter
+       
+      (#) Call TIM_ICInit(TIMx, &TIM_ICInitStruct) to configure the desired channel with the 
+          corresponding configuration and to measure only frequency or duty cycle of the input signal,
+          or,
+          Call TIM_PWMIConfig(TIMx, &TIM_ICInitStruct) to configure the desired channels with the 
+          corresponding configuration and to measure the frequency and the duty cycle of the input signal
+          
+      (#) Enable the NVIC or the DMA to read the measured frequency. 
+          
+      (#) Enable the corresponding interrupt (or DMA request) to read the Captured value,
+          using the function TIM_ITConfig(TIMx, TIM_IT_CCx) (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)) 
+       
+      (#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
+       
+      (#) Use TIM_GetCapturex(TIMx); to read the captured value.
+  [..]        
+      (@) All other functions can be used separately to modify, if needed,
+          a specific feature of the Timer.
