================================================================================ 样例使用说明 Sample Description ================================================================================ 功能描述: 此样例演示了TIM1的输入捕获功能。配置PA8为通道1的输入引脚,每当引脚电平出现上升沿 时会触发捕获中断,并在中断处理中翻转LED。 Function descriptions: This sample demonstrates the input capture functionality of TIM1 . Configure PA8 as the input capture pin. Whenever an rising edge is detected on PA8, it triggers the capture interrupt and toggles the LED in the interrupt callback function. ================================================================================ 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. PA8每给一次上升沿,LED灯翻转一次 Example execution steps: 1.Compile and download the program to the MCU, and then run it. 2.Generate a rising edge on the PA8 pin, and the LED will toggle. ================================================================================ 注意事项: Notes: ================================================================================
