STM32无源蜂鸣器播放音乐《千与千寻》
该工程使用STM32系列微控制器（STM32F4系列）作为主控芯片，连接无源蜂鸣器至GPIO端口，用于生成音频信号。开发工具包括STM32CubeMX（用于外设配置和初始化代码生成）以及Keil uVision或STM32CubeIDE进行代码编写、调试和烧录。硬件资源还包括时钟源（如72 MHz系统时钟）和ST-Link调试器。
软件资源方面，项目使用STM32 HAL库进行硬件抽象，简化GPIO、定时器等外设的操作。音符数据通过MIDI文件提取或手动创建，包含每个音符的频率和时长信息。通过定时器PWM控制信号频率，生成无源蜂鸣器的音高，并利用定时器中断和延时函数精确控制音符的播放时长。
