Within that method, issue serialSendSignal to pass the sendData text data to the signal destination. First, connect sendButtonClicked to the clicked signal of sendButton in the SerialSendView class.
Implemented the process that data is sent from the serial port when the sendButton of SerialSendView is clicked. At this time, if the specified serial port is used by another program, the return value of open will be false. You can enable serial communication by setting the required items such as baud rate and port name in QSerialPort and opening it.
Connect the SerialMonitor portOpen to the signal issued when the ToolBar portOpenButton is clicked, and perform the process of opening the serial port in the connected method. You need to open the serial port to send and receive data on the serial port. By the way, I am making it possible to select flow control, but since I do not implement that function, I just made it possible to select it. Other serial port related items are added as a simple list so that the user can select them in the UI. In order to display the list of serial ports recognized by the PC in this UI, get the list of serial ports with availablePorts of QSerialPortInfo class, get the name of the port with QSerialPort.portName (), and get it. The part related to the serial port is the item added to the QComboBox with the object name portNames of the ToolBar class. It’s basically just adding components to the layout.
