In this example, the EXTI line 9 is configured to generate an interrupt on each falling edge. In the interrupt routine a led connected to PC.06 is toggled. This led will be toggled due to the softawre interrupt generated on EXTI Line9 then at each falling edge. Directory contents ================== stm32f10x_conf.h Library Configuration file stm32f10x_it.h Interrupt handlers header file stm32f10x_it.c Interrupt handlers main.c Main program Hardware environment ==================== - Connect a led to pin PC.06 (LD1 on STM3210B-EVAL board). - Connect a push-button to pin PB.09 (EXTI Line9) (Key push-button on STM3210B-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_exti.c + stm32f10x_nvic.c + stm32f10x_flash.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE******
