Last note, since the Qt libraries are cross platform, here’s the same application running on a Mac: If you try to compile it don’t forget to edit the line “-L/usr/local/lib” in the SerialGUI.pro file to point to where you have the boost libraries installed. It is meant to be compiled with QtCreator.
QT SERIAL PORT BAUD RATE CODE
The code of the QAsyncSerial class and of the GUI example is posted at the end of the original article ( here). Once it is opened, there is a line where to write text to send to the serial port while received text is showed below. This simple GUI allows to select a serial port and open it (the baud rate is fixed to 115200, 8N1 format). To show everything in practice, this is a simple GUI that uses QAsyncSerial running on Linux: It basically emits a signal every time a line is received from the serial port, and because signals and slots are thread safe, the code works as expected.
QT SERIAL PORT BAUD RATE HOW TO
To show how to solve this problem I’ve written a class, called QAsyncSerial which is a wrapper class for AsyncSerial that uses Qt’s system of signals and slots. Well, who has read my article will probably think of using the AsyncSerial class, which allows to register a callback that will be called every time some data arrives from the serial port.īut also this approach won’t work, because of the constraint that the GUI code can be called only from the main thread, but AsyncSerial calls the callback from a separate thread.

In this case the PC application should always listen on the serial port for incoming data.

QT SERIAL PORT BAUD RATE UPDATE
Update : Fixed a bug for compiling under visual studio 2010.
