I need to continuously update a QLCDNumber based on data measurements that I'm pulling from a bench-top instrument. I realize that I will have to put this on some sort of daemon thread to run in the background independently.
I have read a bit about QThreads but am not sure if that is the right approach, or if Qt allows for threading that isn't via QThreads.
You are free to use Python or PyQt threading modules, bot of them work fine, but if you are new to threading I wold recommend to use Qt thread module because it is easier to setup, and If you use Qt Lib. it is easier to implement it in. Even if this is not a complete answer I hope it helps, PS: try to put some code in the question it may help others to test things out
