================================================================================ 样例使用说明 Sample Description ================================================================================ 功能描述: 此样例演示了在sleep模式下,使用GPIO事件唤醒。 Function descriptions: This sample demonstrates using GPIO event to wake up the MCU from sleep mode. ================================================================================ 测试环境: 测试用板:PY32F403_STK MDK版本: 5.28 IAR版本: 9.20 GCC 版本:GNU Arm Embedded Toolchain 10.3-2021.10 Test environment: Test board: PY32F403_STK MDK Version: 5.28 IAR Version: 9.20 GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10 ================================================================================ 使用步骤: 1. 编译下载程序到MCU,并运行; 2. LED灯亮,按下按键,LED灯灭,进入sleep模式; 3. 在PA06上产生一个下降沿,程序退出sleep模式; 4. LED以200ms的间隔进行翻转。 Example execution steps: 1.Compile and download the program to the MCU and run it. 2.The LED lights up. Press the button, and the LED turns off, entering sleep mode. 3.Generate a falling edge on PA06 to wake up the MCU from sleep mode. 4.The LED toggles at an interval of 200ms. ================================================================================ 注意事项: Notes: ================================================================================
