近期需要使用C++进行串口通讯，将Win32 API串口接口进行了下封装，可实现同步通讯，异步回调通讯

1、SerialportMy.h

#pragma once
#include <Windows.h>
#include <thread>
#include <atomic>
#include <functional>
#include <queue>
#include <iostream>
class SerialportMy
{
public:using DataReceivedCallback = std::function<void(const char*, size_t)>;// 模式选择：同步（阻塞）或异步（事件驱动）enum class Mode { Sync, Async };SerialportMy(const char* port = "\\\\.\\COM1", Mode mode = Mode::Sync);~SerialportMy();// 打开串口（波特率/数据位/停止位可配置）bool Open(int baudRate = 9600, int dataBits = 8, int stopBits = 1, bool isStartThread = true);//
