用pyside6写一个带界面的串口工具

好的，下面是一个基于 PySide6 的串口工具示例代码，它包含一个简单的界面和串口通信功能：

import sys
import serial
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QMainWindow, QLabel, QLineEdit, QPushButton, QTextEdit, QVBoxLayout, QWidget

class SerialTool(QMainWindow):
    def __init__(self):
        super().__init__()

        self.serial = None

        # 创建界面控件
        self.port_label = QLabel('Port')
        self.port_edit = QLineEdit('/dev/ttyUSB0')
        self.baudrate_label = QLabel('Baudrate')
        self.baudrate_edit = QLineEdit('9600')
        self.connect_button = QPushButton('Connect')
        self.disconnect_button = QPushButton('Disconnect')
        self.send_button = QPushButton('Send')
        self.recv_text = QTextEdit()

        # 设置控件属性
        self.recv_text.setReadOnly(True)

        # 创建布局
        vbox = QVBoxLayout()
        vbox.addWidget(self.port_label)
        vbox.addWidget(self.port_edit)
        vbox.addWidget(self.baudrate_label)
        vbox.addWidget(self.baudrate_edit)
        vbox.addWidget(self.connect_button)
        vbox.addWidget(self.disconnect_button)
        vbox.addWidget(self.recv_text)
        vbox.addWidget(self.send_button)

        # 创建主窗口
        central_widget = QWidget(self)
        central_widget.setLayout(vbox)
        self.setCentralWidget(central_widget)

        # 连接信号槽
        self.connect_button.clicked.connect(self.connect_serial)
        self.disconnect_button.clicked.connect(self.disconnect_serial)
        self.send_button.clicked.connect(self.send_data)

    def connect_serial(self):
        # 获取串口参数
        port = self.port_edit.text()
        baudrate = int(self.baudrate_edit.text())

        # 打开串口
        self.serial = serial.Serial(port, baudrate, timeout=1)
        if self.serial.isOpen():
            self.recv_text.append('Serial port connected')

    def disconnect_serial(self):
        # 关闭串口
        if self.serial:
            self.serial.close()
            self.recv_text.append('Serial port disconnected')

    def send_data(self):
        # 发送数据
        if self.serial and self.serial.isOpen():
            data = self.send_edit.text()
            self.serial.write(data.encode('utf-8'))

    def closeEvent(self, event):
        # 关闭窗口时断开串口
        if self.serial and self.serial.isOpen():
            self.serial.close()
        super().closeEvent(event)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    tool = SerialTool()
    tool.show()
    sys.exit(app.exec())

这段代码创建了一个带有串口连接、断开、发送和接收功能的界面，你可以根据实际需求修改代码，比如更改界面布局、增加其他控件等。同时，你需要在系统中安装 PySide6 库才能运行这个程序。
