No problem…
The wait time for hold to engage on this function is 3 seconds as opposed to 1 1/2 seconds for all other
functions. You stated “no matter how long you pressed”, is it possible it was not held long enough?
You also stated that it’s now working ok, so I assume you are aware of the longer wait…
There is not much going on in the program at this time, just a loop waiting for the button to be released
and the interrupt decreasing the count. I checked things over, and can’t think of anything else that could
have caused this without causing other obvious problems.
