/******************** * File Name : readme.txt * DESIGN BY : TAN/YICHENG * Date First Issued : 31/03/2008 * Description : Description of the EXTI Example. ******************************************************************************** Example description =================== This example shows how to configure an external interrupt line. In this example, the EXTI line0 is configured to generate an interrupt on each falling edge. In the interrupt routine a led connected to PB10 is toggled. This led will be toggled due to the softawre interrupt generated on EXTI Line0 then at each falling edge. Hardware environment ==================== - Connect a led to pin PB.10 (LD3 on EVAL board). - Connect a push-button to pin PA.00 (EXTI Line0) (Key push-button on EVAL board). - Conect a LED to pin PB.11(LD4 on EVAL board) - Conect a push_button to pin PC.13 (EXTI line13 (Key push-button on 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 + SetClock.c +SetGPIO.c +SetNVIC.c - Link all compiled files and load your image into either RAM or Flash - Run the example 此程序演示了如何配置使用外部中断： WAKEUP 键用来产生外部中断来控制LD3的亮/灭 TAMPER 键用来产生外部中断来控制LD4的亮/灭
