================================================================================ 样例使用说明 Sample Description ================================================================================ 功能描述: 此样例配置系统时钟为HSI,并通过MCO(PA08)引脚输出。 Function descriptions: This sample configures the system clock to use the HSI (High-Speed Internal) clock source and outputs it through the MCO (PA08) pin. ================================================================================ 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. 使用示波器监测PA08引脚上的频率,观察是否与配置的HSI频率一致; Example execution steps: 1. Compile and download the program to the MCU and run it; 2. Use an oscilloscope to monitor the frequency on the PA08 pin and check if it matches the configured HSI frequency. ================================================================================ 注意事项: Notes: ================================================================================
