I have a Pi3 and I am trying out the example http://pi4j.com/example/listener.html which is a GPIO state listener.
My issue is the following:
When I press (close) the contact, I get one
When I release (open) the contact, I get
I tried to
debounce() the events:
which really debounces the events. It means, with the contact opened I get only one (in fact two, it's one
LOW immediately followed by a
HIGH) per second.
I would like to get an event only on state changes.
How can that be achieved?
It could be related to this issue https://github.com/Pi4J/pi4j/issues/121
Only difference is, I don't get the state changes randomly, but permanently in case the contact is open.
Here someone has the same problem: https://groups.google.com/d/msg/pi4j/hdVvEBCpRZc/HOdWFcSyHpIJ
I opened an issue on pi4j's github about this problem: https://github.com/Pi4J/pi4j/issues/300
At the end I was unable to reproduce the issue.
