I have a state machine and within one of the states i have a while loop where I poll a device every 20 seconds. I am using a wait timer for 20 seconds to perform the polling. The problem is that I have a stop button for the loop, but it does not stop when I press the button.
Is there a better way to poll the device every 20 seconds which gives me the flexibility to stop the loop whenever I want?
Thanks,
Gary
