核心硬件
主控单元采用STM32MP157A单片机凭借其强大的处理能力和丰富的外设接口为系统提供了坚实的硬件基础。
软件平台
开发工具利用STM32CUBEIDE这一直观易用的集成开发环境极大地提升了软件编程与调试的效率确保了系统软件的稳定可靠。
系统功能亮点 模式灵活切换通过串口通信用户可以轻松地在闹钟、音乐盒播放及温湿度监测三种模式之间自由切换满足不同场景下的使用需求。 动态信息显示点阵屏作为系统的信息展示窗口能够根据当前的工作模式显示相应的汉字如“钟”代表闹钟模式“音”代表音乐盒模式“传”可视为温湿度监测的简化标识为用户提供了直观的操作反馈。 按键交互体验设计中充分考虑了用户的交互体验通过按键即可在各模式下执行对应的功能操作如音乐盒的速度与音量调节、歌曲切换、暂停/播放控制以及闹钟的时间调整、设置多个闹钟、关闭闹钟等。 温湿度智能调控系统内置温湿度传感器能够实时监测环境状况并通过串口接收用户指令调节温湿度的上下限阈值。一旦环境参数超出设定范围LED指示灯将亮起作为边界提示帮助用户及时采取措施。 二、基本配置信息 音乐盒在之前做过所以配置不做改变STM32音乐盒 三、STM32CUBEIDE配置 1、定时器--100ms 2、PWM配置蜂鸣器 -- PB6 3. 串口配置 注意针脚 4. IIC配置温湿度数码管点阵屏 5. GPIO配置LED和按键 6. NVIC 四、程序编写
