@par Example Description 

This example shows how to configure the SysTick to generate a time base equal to
1 ms. The system clock is set to 24 MHz on Value line devices and to 72 MHz on 
other devices, the SysTick is clocked by the AHB clock (HCLK).

A "Delay" function is implemented based on the SysTick end-of-count event.
Four LEDs are toggled with a timing defined by the Delay function.

@par Hardware and Software environment 

  - This example runs on STM32F10x Connectivity line, High-Density, High-Density 
    Value line, Medium-Density, XL-Density, Medium-Density Value line, 
    Low-Density and Low-Density Value line Devices.
  
  - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
    Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL 
    (Connectivity line), STM3210E-EVAL (High-Density and XL-Density) 
    and STM3210B-EVAL (Medium-Density) evaluation boards and can be easily
    tailored to any other supported device and development board.
    To select the STMicroelectronics evaluation board used to run the example, 
    uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL)

@par How to use it ? 

In order to make the program work, you must do the following :
 - Copy all source files from this example folder to the template folder under
   Project\STM32F10x_StdPeriph_Template
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example
