@par Example Description 

How to use the default SysTick configuration with a 1 ms timebase to toggle LEDs

  The system clock is set to 72 MHz for STM32F3 devices, the SysTick is 
  clocked by the AHB clock(HCLK).

  A "HAL_Delay" function is implemented based on the SysTick end-of-count event.
  Four LEDs are toggled with a timing defined by the HAL_Delay function.
 
  @note: Caution, the SysTick time base 1 msec must not be changed due to use 
         of these time base by HAL driver.

@par Hardware and Software environment 

  - This example runs on STM32F303xC device.

  - This example has been tested with STM32F3_DISCOVERY board and can be
    easily tailored to any other supported device and development board.    


@par How to use it ? 

In order to make the program work, you must do the following :
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example
