Timer for a button or loop.

[mithishan]

Hey, so I have a data assistant and write to measurement file in two separate loops. The daq is connected to a pressure sensor. Now I need to monitor the pressure levels before, during and after the experiment. But I don't want the data to be logged before and after. The experiment would run for 10 seconds. So how do I create a timer and buttons such that, I use one button to start the code and see the pressure values, and one button to start the data logging along with the timer. And it to stop logging the data after the time. Please help.

Look into a simple state machine architecture and things will fall in place.

No need for a FGV if a proper state machine is programmed. I would have a "Timer" state would keep track of the elapsed time, trigger a data collection interval, and stop after the programmed test duration.
