@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.
