Example description 
=================== 
This example demontrates the use of the Nested Vectored Interrupt Controller (NVIC) 
IRQ Channels configuration:  
 
- Configuration of 3 TIM (TIM2..TIM4)timers to generate an interrupt on each  
  counter update event. 
- The three timers are linked to their correspondant Update IRQ channel. 
- Assignment of a ascendant IRQ priority for each IRQ channel : 
  TIM2 has a preemption priority of 0 and TIM4 has a preemption priority of 2. 
- In each interrupt routine:  
   - TIM2 toggles a LED1 each 1s  
   - TIM3 toggles a LED2 each 2s  
   - TIM4 toggles a LED3 each 3s  
 
 
Directory contents 
================== 
stm32f10x_conf.h  Library Configuration file 
stm32f10x_it.c    Interrupt handlers 
stm32f10x_it.h    Interrupt handlers header file 
main.c            Main program 
 
 
Hardware environment 
==================== 
This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation 
boards and can be easily tailored to any other hardware. 
To select the STMicroelectronics evaluation board used to run the example, uncomment 
the corresponding line in platform_config.h file. 
 
 + STM3210B-EVAL  
    - Use LD1, LD2 and LD3 leds connected respectively to PC.06, PC.07 and PC.08 
  
 + STM3210E-EVAL 
    - Use LD1, LD2 and LD3 leds connected respectively to PF.06, PF0.7 and PF.08 
 
How to use it 
============= 
In order to make the program work, you must do the following : 
- Create a project and setup all your toolchain's start-up files 
- Compile the directory content files and required Library files : 
  + stm32f10x_lib.c 
  + stm32f10x_gpio.c 
  + stm32f10x_rcc.c 
  + stm32f10x_nvic.c 
  + stm32f10x_tim.c 
  + stm32f10x_flash.c 
     
- Link all compiled files and load your image into target memory 
- Run the example
