TIM5 Driver: how to use it in Timing(Time base) Mode
===================================================================
To use the Timer in Timing(Time base) mode, the following steps are mandatory:
1. Enable TIM5 clock using CLK_PeripheralClockConfig(CLK_Peripheral_TIM5, ENABLE) function.
2. Call TIM5_TimeBaseInit() to configure the Time Base unit with the
corresponding configuration.
3. Enable global interrupts if you need to generate the update interrupt.
4. Enable the corresponding interrupt using the function TIM5_ITConfig(TIM5_IT_Update)
5. Call the TIM5_Cmd(ENABLE) function to enable the TIM5 counter.
Note1: All other functions can be used separately to modify, if needed,
a specific feature of the Timer.

TIM5 Driver: how to use it in Output Compare Mode
===================================================================
To use the Timer in Output Compare mode, the following steps are mandatory:
1. Enable TIM5 clock using CLK_PeripheralClockConfig(CLK_Peripheral_TIM5, ENABLE) function.
2. Configure the TIM5 pins in output 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 = 0x0000
- Counter mode = Up counting
4. Call TIM5_OCxInit() to configure the channel x with the desired parameters
including:
- TIM5 Output Compare mode: TIM5_OCMode
- TIM5 Output State: TIM5_OutputState
- TIM5 Pulse value: TIM5_Pulse
- TIM5 Output Compare Polarity: TIM5_OCPolarity
- TIM5 Output Idle State: TIM5_OCIdleState
5. Call the TIM5_Cmd(ENABLE) function to enable the TIM5 counter.
Note1: All other functions can be used separately to modify, if needed,
a specific feature of the Timer.
Note2: If the corresponding interrupt or DMA request are needed, the user should:
1. Enable global interrupts (or the DMA) to use the TIM5 interrupts (or DMA requests).
2. Enable the corresponding interrupt (or DMA request) using the function
TIM5_ITConfig(TIM5_IT_CCx) (or TIM5_DMACmd(TIM5_DMASource_CCx))

===================================================================
TIM5 Driver: how to use it in Input Capture Mode
===================================================================
To use the Timer in Input Capture mode, the following steps are mandatory:
1. Enable TIM5 clock using CLK_PeripheralClockConfig(CLK_Peripheral_TIM5, ENABLE) function.
2. Configure the TIM5 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 TIM5_ICInit() to configure the desired channel to measure only
frequency or duty cycle of the input signal using the corresponding configuration:
- TIM5 Channel: TIM5_Channel
- TIM5 Input Capture polarity: TIM5_ICPolarity
- TIM5 Input Capture selection: TIM5_ICSelection
- TIM5 Input Capture Prescaler: TIM5_ICPSC
- TIM5 Input Capture filter value
or,
Call TIM5_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 TIM5_ITConfig(TIM5_IT_CCx) (or TIM5_DMACmd(TIM5_DMASource_CCx))
7. Call the TIM5_Cmd(ENABLE) function to enable the TIM5 counter.
8. Use TIM5_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.
