Qt串口短接自动获取串口并收发检测以线程开启方式

好的,我会尽力回答你的问题。
首先,你需要先在Qt中安装串口库QSerialPort。接下来,你可以使用以下代码自动获取可用的串口:
```cpp
QList<QSerialPortInfo> availablePorts = QSerialPortInfo::availablePorts();
foreach (const QSerialPortInfo &portInfo, availablePorts) {
QString portName = portInfo.portName();
// Do something with the port name
}
```
然后,你可以使用以下代码来打开串口并进行收发检测:
```cpp
QSerialPort serialPort;
serialPort.setPortName(portName); // Replace portName with the name of the selected port
serialPort.setBaudRate(QSerialPort::Baud9600); // Set the baud rate to 9600 (or whichever you need)
serialPort.open(QIODevice::ReadWrite); // Open the port for reading and writing
// Start a separate thread to read data from the serial port
QThread* readThread = new QThread();
SerialPortReader* reader = new SerialPortReader(&serialPort); // Replace SerialPortReader with your own class that reads data from the serial port
reader->moveToThread(readThread); // Move the reader object to the thread
connect(readThread, SIGNAL(started()), reader, SLOT(process()));
connect(reader, SIGNAL(finished()), readThread, SLOT(quit()));
connect(reader, SIGNAL(finished()), reader, SLOT(deleteLater()));
connect(readThread, SIGNAL(finished()), readThread, SLOT(deleteLater()));
readThread->start();
// Write data to the serial port
serialPort.write("Hello, Arduino!");
// Close the serial port when you're done
serialPort.close();
```
以上代码仅是一个简单的示例,你需要根据自己的具体需求进行修改。同时,你需要自己实现一个能够从串口读取数据的类,并在单独的线程中进行读取。
