If you are running your own infinite loop anywhere in the code, the GUI will freeze up.īoth methods achieve basically the same goal of updating the GUI.įor example, a Serial.readline() wont print anything until there is a whole line to return, which in some cases might be never Even using the after() and update() methods will still not allow the UI to be updated in this case, since the function never ends. It needs the things in there to run every now and then in order to make the interface respond to interactions. Keep in mind that when TkInter gets to the root.mainloop() method, it is running its own while loop. The process cannot update buttons or react to input because it is busy waiting for the serial to say something.
