c++ - Connecting to Serial port in QT - Stack Overflow
stackoverflow.com › questions › 26994742Nov 19, 2014 · 1. I'd like to connect to a microcontroller using QSerialPort. I've added the line serial port to my .pro file, included QSerialPort in my source file and ran qmake. My code is below: serial.setPortName ("COM3"); serial.setBaudRate (QSerialPort::Baud9600); serial.setDataBits (QSerialPort::Data8); serial.setParity (QSerialPort::NoParity); serial.setStopBits (QSerialPort::OneStop); serial.setFlowControl (QSerialPort::NoFlowControl); serial.open (QIODevice::ReadWrite); serial.write ("ok*");
Terminal Example | Qt Serial Port 6.4.2
