第一次海报长期读者。

我一直在玩从蓝牙 GPS 单元读取数据。我可以使用 hyperterm 连接到它并查看数据

问题 我在换行时留下了换行符，C++ 输出有额外的换行符，不知道为什么？C++ 日志也有一些时髦的字符......？

编码

    for (int n=0;n<100;n++) {
        char INBUFFER[100];
        cv::waitKey(1000);
        bStatus = ReadFile(comport,   // Handle
                &INBUFFER,            // Incoming data
                100,                  // Number of bytes to read
                &bytes_read,          // Number of bytes read
                NULL);

        cout << "bStatus " << bStatus << endl;
        if (bStatus != 0)
        {
            // error processing code goes here
        }
        LogFile << INBUFFER;
    }

我正在使用设置...

    comSettings.BaudRate = 2400;
    comSettings.StopBits = ONESTOPBIT;
    comSettings.ByteSize = 8;
    comSettings.Parity   = NOPARITY;
    comSettings.fParity  = FALSE;

...据我所知，这与 hyperterm 使用的设置相同。关于我做错了什么的任何提示？

干杯！

更新 因此，在更新为使用 bytes_read 并在 NMEA 数据末尾考虑额外的 LF 之后，我现在拥有...

    if (bytes_read!=0) {
        for (int i=0; i < bytes_read; i++) {
            LogFile << INBUFFER[i];
        }
    }

这似乎有固定的东西！

谢谢大家，非常感谢您的帮助。

你有一个bytes_readvar，但你什么都不做？INBUFFER在我看来，无论实际加载了多少/几个字节，您都将整个文件转储到文件中？
