@par Example Description 

This example shows how to configure the TIM peripheral to generate four different 
signals with four different delays.

The TIMxCLK frequency is set to 36 MHz, the Prescaler is set to 35999 and used in 
Output Compare Active Mode.
 
TIM3 counter clock = TIMxCLK / (Prescaler +1) = 1 KHz 

The TIM3 CCR1 register value is equal to 1000:
TIM3_CH1 delay = CCR1_Val/TIM3 counter clock  = 1000 ms
so the TIM3 Channel 1 generates a signal with a delay equal to 1000 ms.

The TIM3 CCR2 register value is equal to 500:
TIM3_CH2 delay = CCR2_Val/TIM3 counter clock = 500 ms
so the TIM3 Channel 2 generates a signal with a delay equal to 500 ms.

The TIM3 CCR3 register value is equal to 250:
TIM3_CH3 delay = CCR3_Val/TIM3 counter clock = 250 ms
so the TIM3 Channel 3 generates a signal with a delay equal to 250 ms.

The TIM3 CCR4 register value is equal to 125:
TIM3_CH4 delay = CCR4_Val/TIM3 counter clock = 125 ms
so the TIM3 Channel 4 generates a signal with a delay equal to 125 ms.

The delay correspond to the time difference between PC.06 and 
TIM3_CHx signal rising edges in case of STM3210E-EVAL and STM3210B-EVAL 

The delay correspond to the time difference between PD.07 and 
TIM3_CHx signal rising edges in case of STM3210C-EVAL

@par Hardware and Software environment 

  - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density 
    and Low-Density Devices.
  
  - This example has been tested with STMicroelectronics STM3210C-EVAL (STM32F10x 
    Connectivity line), STM3210E-EVAL (STM32F10x High-Density) and STM3210B-EVAL
    (STM32F10x Medium-Density) evaluation boards and can be easily tailored to
    any other supported device and development board.
    

  - STM3210C-EVAL Set-up 
    - Connect the TIM3 pins(TIM3 full remapped pins) to an oscilloscope to monitor the different waveforms:
       - PD.07
       - PC.06 (TIM3_CH1)
       - PC.07 (TIM3_CH2)
       - PC.08 (TIM3_CH3)
       - PC.09 (TIM3_CH4)

  - STM3210E-EVAL and STM3210B-EVAL Set-up 
    - Connect the following pins to an oscilloscope to monitor the different 
      waveforms:
       - PC.06
       - PA.00 (TIM3_CH1)
       - PA.01 (TIM3_CH2)
       - PA.02 (TIM3_CH3)
       - PA.03 (TIM3_CH4)
  
@par How to use it ? 

In order to make the program work, you must do the following:
- Create a project and setup all project configuration
- Add the required Library files:
  - stm32f10x_flash.c 
  - stm32f10x_gpio.c 
  - stm32f10x_rcc.c
  - stm32f10x_tim.c 
  - system_stm32f10x.c (under Libraries\CMSIS\Core\CM3) 
    
- Edit stm32f10x.h file to select the device you are working on.
  
@b Tip: You can tailor the provided project template to run this example, for 
        more details please refer to "stm32f10x_stdperiph_lib_um.chm" user 
        manual; select "Peripheral Examples" then follow the instructions 
        provided in "How to proceed" section.   
- Link all compiled files and load your image into target memory
- Run the example

@note
 - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 16 and 32 Kbytes.
 - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 32 and 128 Kbytes.
 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 256 and 512 Kbytes.
 - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
