I prefer to use the multi-thread method beacause it's easier for me and my colaborators to have the entire acquisition process at the same place. Until then I use a simple one but I hope to use a more complex one in few weeks ( put different voltages on different devices then measure many voltages or current). If I use the "domino" technique (call the next operation by the end of the previous) it can be complex to read and to edit. Thank you very much anyway!
How can I write a multi-thread process? I've just tried to add qApp.processEvents() at the end of my while loop but it doesn't change anything...
