beginner's question

[David DuPuy]

Could someone please give me some ideas on the following? How can I keep
track of the number of times a button is pushed, and then go do something
after the button has been pushed three times? Seems like there ought to be
a "event counter" tool, but I can't find one. Can the shift register
feature be used here? thanks, and remove the 'ABC' if you email me direct
(which is welcome).... David

Yes a shift register would be a good way to go. Just use initialize one to zero, then use the increment function everytime the button is pressed. See the attached example.

David,
There are a few ways, including use of counters and occurences.
Attached is a simple method using a shift register, compare logic, and a Case to open a dialog window (which you could change the insides as needed).
See if it gives you some ideas.
Good luck, Doug

You've got it. Stick the button in a while loop with a shift register
initialised to 0, wire the button to a case structure and set the mechanical
action to "latch when released". Now the wire the shift register into the
case statement. Now you need to check the the shift register value is 2 or
less. Wire the output of the "<" to another case statement the true case is
where you put your action and zero the shift register, the false is where
you increment the shift register
