+Example description
+===================
+This example provides a short description of how to use the JTAG IOs as standard
+GPIOs and gives a configuration sequence.
+
+First, the SWJ-DP is disabled. The SWJ-DP pins are configured as output push-pull.
+Five LEDs connected to the 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 the host debugger is
+lost and cannot be re-established as long as the JTAG IOs remain disabled.
+To avoid this situation, a specified pin is connected to a push-button that is used
+to disable or not the JTAG IOs:
+ 1. push-button pressed at reset: JTAG IOs disabled
+ 2. push-button not pressed at reset: JTAG IOs unchanged
+
+
+Directory contents

+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
+ - Connect five leds to pins PA.13, PA.14, PA.15, PB.03 and PB.04.
+ - Use the Key push-button connected to pin PB.09 (EXTI Line9).
+
+ + STM3210E-EVAL
+ - Connect five leds to pins PA.13, PA.14, PA.15, PB.03 and PB.04.
+ - Use the Key push-button connectedto pin PG.08 (EXTI Line8).
+
+
+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 target memory
+- Run the example
