基于STM32屏显菜单系统

功能

本设计将要实现一个以单片机为核心的屏显菜单系统设计。以单片机STM32单片机作为主控芯片，通过按键选择不同的选项，显示不同的界面功能。在界面部分主要显示菜单栏、时间、图片、音乐等功能。
掌握与研究的内容有以下几个方面：
（1）研究屏幕SPI通信方式。
（2）研究单总线通信协议。
（3）研究菜单步进系统设计。
（4）研究使用Keil编程环境编写单片机代码。

硬件

屏显菜单系统硬件如图1所示。硬件部分主要包括单片机最小系统、电源、按键模块、时钟模块、显示模块、语音模块。单片机检测不同按键按下，进行屏幕菜单选项选择，按下确定键后实现选项功能，可以选择时间显示，图片显示等功能。
