+# UartDevice模块
+该模块是UART设备接口模块，提供了UART 设备操作接口，通过uart通信操作相关的硬件设备。
+
+# 涉及的知识
+* uart通信协议
+* 多线程
+* 系统调用函数的使用
+* C++类和对象
+* 函数指针
+
+
+# 各文件的作用
+* **UartDevice.h**：定义了一个名为uart_info的结构体存储UART设备的配置信息，定义了用于UART通信的函数接口，这些函数通常与UART硬件的底层实现相对应。
+* **UartDevice.cpp**：提供了一个跨平台的UART设备接口模块，使得上层应用可以通过统一的接口来操作不同的UART硬件设备。
+* **UartDeviceImpl.cpp**：提供了UART 设备操作接口，允许用户打开、发送和接收数据到 UART 设备，实现了 UART 设备的配置、数据发送和接收等功能。
+* **UartDeviceImpl.h**：定义了一个用于UART设备操作的类 UartDeviceImpl 和相关的结构体和函数，提供了一种通过接口和智能指针封装具体实现的方式来管理UART设备。
