Hi everyone!
Im stuck...
I'm currently writing a GUI program to control a piece of machinery. I am using wxPython along with a few other bits and bobs including USPP for serial access.
My problem is that i need some way of 'pinging' the machine. ie I want to be able to regularly send an 'are you still there' message to the on board hardware, receive a simple yes or no and not really know it has done anything (must not interrupt the usability of the program)
Ive done some searching and i think threads must be the answer here but that is totally new territory for me...
Any help would be greatly appreciated :-)
Thanks,
Mark :mrgreen:

sure...
clearly there will be a little more to it in the end... lol, but that seems to do the trick.
Starts a new thread that repeats an action every 'x' seconds. The rest of the progam can continue as normal. Jobs-a-goodun :-)
One thing to note is that its a good idea to close the thread when the program exits...
Not sure how it would work with more than 1 thread but 1 is all i need :-)
