C++ accessport软件代码

如果你是指通过C++编写一个类似AccessPort软件的串口调试工具，那么这个工作量比较大，需要涉及到图形界面、串口通信、数据解析等多个方面的知识。但是，我可以给你提供一个简单的串口通信代码，可以作为你实现一个串口调试工具的基础。

#include <iostream>
#include <Windows.h>

int main()
{
    HANDLE hCom;
    char buffer[1024];
    DWORD bytesRead;

    // 打开COM1串口
    hCom = CreateFileA("COM1", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);

    if (hCom == INVALID_HANDLE_VALUE) {
        std::cout << "Failed to open COM port!\n";
        return 1;
    }

    // 配置串口参数
    DCB dcb;
    memset(&dcb, 0, sizeof(DCB));
    dcb.DCBlength = sizeof(DCB);

    if (!GetCommState(hCom, &dcb)) {
        std::cout << "Failed to get COM port state!\n";
        CloseHandle(hCom);
        return 1;
    }

    dcb.BaudRate = CBR_9600;
    dcb.ByteSize = 8;
    dcb.Parity = NOPARITY;
    dcb.StopBits = ONESTOPBIT;

    if (!SetCommState(hCom, &dcb)) {
        std::cout << "Failed to set COM port state!\n";
        CloseHandle(hCom);
        return 1;
    }

    // 不断从串口读取数据并输出
    while (true) {
        if (!ReadFile(hCom, buffer, sizeof(buffer), &bytesRead, NULL)) {
            std::cout << "Failed to read from COM port!\n";
            CloseHandle(hCom);
            return 1;
        }

        if (bytesRead > 0) {
            std::cout << "Received " << bytesRead << " bytes: " << buffer << "\n";
        }

        // 从标准输入读取数据并发送到串口
        if (fgets(buffer, sizeof(buffer), stdin) != NULL) {
            DWORD bytesWritten;

            if (!WriteFile(hCom, buffer, strlen(buffer), &bytesWritten, NULL)) {
                std::cout << "Failed to write to COM port!\n";
                CloseHandle(hCom);
                return 1;
            }

            std::cout << "Sent " << bytesWritten << " bytes: " << buffer;
        }
    }

    CloseHandle(hCom);
    return 0;
}

这个代码使用了Windows API函数来进行串口通信，包括打开串口、配置串口参数、读取串口数据和发送数据到串口等操作。你可以将此代码编译运行后，向串口发送数据并通过标准输入输入数据，就能进行简单的串口通信了。
