Question

I’m trying to create a periodic callback using QT. I’m thinking, something like OpenGL’s periodic callback.

Basically, I have a micro controller which is waiting for an event to happen. When the event Happens it sends the time over the serial port to the PC. On the PC side, I want the GUI to update whenever this time information is received, or to periodically check to see if there is anything in the Rx buffer.

Is there any built in functionality of Qt to periodically call a methood?

If not is there a way to create a signal between QextSerial, and The GUI?

Or, will I have to make a multi-threaded app with an observer/observable relationship between the serialPort, and the GUI?.

Have a look at QTimer. They also list an example of an analog clock
