32 DllMain hook strProductName2 : C:\qt_example\build- 1 There is 1 USB Type C port ,a GROVE connector and an expansion port The. The connection is OK and I found out it by qDubug. The function that reads the data is called.I just tried the following code. When data comes in from the serial port, the readyRead signal will be triggered. App 2 must wait until App 1 closes the port. When App 1 opens a serial port, App 2 cannot use the same serial port. i want to send data in serial i write code like QString cmdui->lineEdit->text(). Only users with topic management privileges can see it. If you have 2 apps on the same computer that want to use the same serial port, then only one of the programs can use the serial port at a time. Qt Development General and Desktop serial communication serial communication. QDebug()<<"The alcohol serial port has been opened" Is it possible to open the port in both Qt app and Arduino in a same OS. Judge whether the serial port is open and call the ispen() function if(SerialPort.isOpen()) In this mode, data can only be read from the serial port, not written SerialPort.open(QIODevice::ReadOnly) //Open the serial port and set the serial port to read-only mode Open the serial port and set the open mode
tFlowControl(QSerialPort::NoFlowControl) //Set flow control (none) This will allow us to enable and disable the serial input/output interface.
#Qt serial communication update
tStopBits(QSerialPort::OneStop) //Set stop bit (one bit) Software: First, open the terminal and use the following commands to update and upgrade your Pi: sudo apt-get update sudo apt-get upgrade. Arduino uses digital pins 0 (RX) and 1 (TX), for serial port communication. Arduino and computer are connected by USB. tParity(QSerialPort::NoParity) //Set parity check (none) The Qt GUI for Arduino is an application that allows connecting Arduino Uno/Mega boards with Desktop operating systems, the communication between Arduino and computer happens over Serial Port channel. tDataBits(QSerialPort::Data8) //Set data bit (8) Set baud rate tBaudRate(QSerialPort::Baud115200) //Set serial port baud rate (9600) Qdebug() < < "serial port information not found, please check whether the device is connected" QDebug() << "System Location: " << SerialPortInfo.systemLocation() // System location QDebug() << "Serial Number: " << rialNumber() // Serial port number QDebug() << "Manufacturer: " << SerialPortInfo.manufacturer() QDebug() << "Description : " << scription() // Serial port description QDebug() << "Name : " << SerialPortInfo.portName() // Serial port name, such as com3 The specific information is as follows:" Qdebug() < < "the required serial port has been found. If(info.portName() "COM10") //Use the if statement to determine whether the serial port is required Here, select the serial port named COM10 and output the specific information of the serial portįoreach (const qserialportinfo & info, qserialportinfo:: availableports()) / / search for serial ports and obtain the list of serial ports QDebug()< To use the serial port, you must instantiate a QSerialPort class and configure parameters through the instantiated object. QSerialPort class: provides the function of accessing the serial port. The serial port in Qt uses QSerialPort and QSerialPortInfo, and the use of these two classes must add the serialport module, that is, the serial port module, to the project file.
