Overview

A very simple example for showing how to keep count of the number of times a button is pressed using event Structure.

 

 

Description

A simple while loop with an event structure.  If the event is a timeout, Count is not increased.  If the event is a button press, increment Count. The steps are shown below:

1. Initialize the shift register to 0 to reset the counter each new run
2. Increment the count when the user presses the button
3. If the user didn't press the button, pass the count as it is
4. Update the count value on the front panel
