[Qt-interest] Some guidance asked

[Kari Laine]

Hi,

I am writing a Linux-version of oscilloscope program for Velleman PCSGU250.
Now I have the userinterface mostly done. I still have to do some of
the dynamics of the interface.

I have done the communication to scope with C using libusb and it works.

The useinterface is running on the main thread. I am considering using
own thread to read the scope data.
and maybe use own thread to send data to scope and function generator.
Is this the right way?
Is it possible to have shared buffer in between the userinterface
thread and worker threads?

How can I call C-routines from QT?

How I draw the data oscilloscope sent,  to the QWidget, which is the
output window of the scope.

As you notice these are quite stupid questions - I am just after how
to put it all together.
Any comments highly appreciated. And I am not much a programmer ...


Best Regards
Kari
