In this example, an EXTI line is configured to generate an interrupt on each falling edge. In the interrupt routine a led connected to a specific GPIO pin is toggled. This led will be toggled due to the softawre interrupt generated on the EXTI Line then at each falling edge. Directory contents ================== platform_config.h Evaluation board specific configuration file stm32f10x_conf.h Library Configuration file stm32f10x_it.h Interrupt handlers header file stm32f10x_it.c Interrupt handlers 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 led connected to PC.06 pin - Use the Key push-button connected to pin PB.09 (EXTI Line9). + STM3210E-EVAL - Use LD1 led connected to PF.06 pin - Use the Key push-button connected to 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_exti.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******
