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 ================== platform_config.h Evaluation board specific configuration file 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 ==================== 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 ******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE******
