将工程文件夹中的“音频文件放在SD卡根目录下”文件夹的内容复制到Micro SD卡根目录中，把Micro SD卡插入开发板的卡槽内，使用USB将开发板上的“USB转串口”接口接到电脑，电脑端配置好串口调试助手参数。编译实验程序并将其下载到开发板上，程序运行后在串口调试助手可接收到开发板发过来的提示信息，如果没有提示错误信息，则可听到音乐，播放完首后自动切换下一首，如此循环。
Copy the contents of the folder "audio files in the root directory of SD card" in the project folder to the root directory of micro SD card, insert the micro SD card into the card slot of the development board, use USB to connect the "USB to serial port" interface on the development board to the computer, and configure the serial port debugging assistant parameters on the computer. Compile the experimental program and download it to the development board. After the program runs, the serial debugging assistant can receive the prompt message from the development board. If there is no error message, you can hear the music, and automatically switch to the next one after playing the first one, so as to loop. (2021-04-14, C/C++, 11678KB, 下载0次)
