Detailed Description#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Use the static availablePorts() function to generate a list of QSerialPortInfo objects. Each QSerialPortInfo object in the list represents a single serial port and can be queried for the port name , system location , description , manufacturer , and some other hardware parameters. The QSerialPortInfo class can also be used as an input parameter for the setPort() method of the QSerialPort class.

Example Usage#

The example code enumerates all available serial ports and prints their parameters to console:

serialPortInfos = QSerialPortInfo.availablePorts()
for portInfo in serialPortInfos:
    print("\n")
             << "Port:" << portInfo.portName() << "\n"
             << "Location:" << portInfo.systemLocation() << "\n"
             << "Description:" << portInfo.description() << "\n"
             << "Manufacturer:" << portInfo.manufacturer() << "\n"
             << "Serial number:" << portInfo.serialNumber() << "\n"
             << "Vendor Identifier:"
             << (portInfo.hasVendorIdentifier()
                 ? QByteArray.number(portInfo.vendorIdentifier(), 16)
                 : QByteArray()) << "\n"
             << "Product Identifier:"
             << (portInfo.hasProductIdentifier()
                 ? QByteArray.number(portInfo.productIdentifier(), 16)
super().__init__())

class PySide6.QtSerialPort.QSerialPortInfo#

PySide6.QtSerialPort.QSerialPortInfo(port)

PySide6.QtSerialPort.QSerialPortInfo(other)

PySide6.QtSerialPort.QSerialPortInfo(name)

Parameters:

Constructs an empty QSerialPortInfo object.

See also

isNull()

Constructs a QSerialPortInfo object from serial port.

Constructs a copy of other.

Constructs a QSerialPortInfo object from serial port name.

This constructor finds the relevant serial port among the available ones according to the port name name, and constructs the serial port info instance for that port.

bool

Returns true if there is a valid 16-bit product number present; otherwise returns false.

PySide6.QtSerialPort.QSerialPortInfo.hasVendorIdentifier()#
Return type:

bool

Returns true if there is a valid 16-bit vendor number present; otherwise returns false.

PySide6.QtSerialPort.QSerialPortInfo.isNull()#
Return type:

bool
