Example description
===================
This example provides a short description of how to use the JTAG IOs as standard 
GPIOs and gives a configuration sequence. 
Five leds connected to PA.13(JTMS/SWDAT), PA.14(JTCK/SWCLK), PA.15(JTDI), PB.03(JTDO)
and PB.04(JTRST) pins are toggled in an infinite loop.

Note that once the JTAG IOs are disabled, the connection with host debugger is lost
and can't be established again while the JTAG IOs are disabled.	
To avoid such situation a pin, PB.09, connected to a push button is used to select
between disabling or not the JTAG IOs:
  - push button pressed at reset: JTAG IOs disabled
  - push button not pressed at reset: JTAG IOs not changed


Directory contents
==================
stm32f10x_conf.h  Library Configuration file
stm32f10x_it.c    Interrupt handlers
stm32f10x_it.h    Header for stm32f10x_it.c
main.c            Main program


Hardware environment
====================
 - Connect four leds to pins PA.13, PA.14, PA.15, PB.03 and PB.04. 
 - Connect a push button to pin PB.09 (Key push button on STM32F10x-EVAL board).
      
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_flash.c
    
- Link all compiled files and load your image into either RAM or Flash
- Run the example
