基于单片机的手势识别音乐播放器 中文摘要□□本设计在理解 STM32F030F4P6 芯片的技术特点和明确音乐播放器的主要功能的基础上，提出了一种基于单片机的音乐播放器软硬件设计的具体实现方法，并运用手势识别的方式对音乐播放器进行简单的操作，最后通过实际电路的调试以及相关程序的编写实现了音乐播放器的制作。设计中采用了 STM32F030F4P6 单片机作为音乐播放器的中央控制器，并通过 QJ008-16s 音频芯片对外置 TF 卡上的 MP3、WMV 格式的音频文件进行读取操作，然后进行音频解码，实现歌曲播放功能。用户可以通过手势或者物理按键进行歌曲的选择以及音量的调节，还可以通过 OLED 屏幕上的显示以调节闹钟、时钟、休眠的相关设置。在最后的系统测试中表明，该音乐播放器在保留了播放音乐的基本功能的前提下，成功实现了手势识别操作，其他功能也能正常运行，达到了既定的设计要求。关键词：单片机 音乐播放器 手势识别 音频解码Abstract This project analyzes the technical characteristics of STM32F030F4P6 microcontroller and the main functions of audio player, putting forward a method of hardware and software design of audio player based on single chip microcomputer, and the use of gesture recognition to the audio player simple operation. Finally, through the actual circuit debugging and related programming to achieve the audio player production. In the project, STM32F030F4P6 microcontroller is used as the central controller of the audio player, and Qj008-16s audio chip is used to read MP3 and WMV audio files on the external TF card, and then conduct audio decoding to realize the music playback function. Users can choose songs and adjust the volume through gestures or physical buttons. They can also adjust the alarm clock, time clock, sleep setting and other relevant settings through the display on the OLED screen. It was shown in the final system test, on the premise of keeping the basic function of playing music, the audio player successfully realizes ges...
