PuckJS button event issues.

Posted on
  • Hi All,

    I am getting some issues with my code to handle the button event on the puck js. I think puck is too sensitive that its button event is fired even on movement of device. How can i improve this. Is their any documentation for what are all possible options we can pass to


    Code which i am using is as followed. Please


    Should i use debounce, Can you give me some idea about debounce what is use of this.

  • Hi, there's quite a bit of documentation on setWatch in the Espruino reference: http://www.espruino.com/Reference#l__glo­bal_setWatch

    Yes you should use debounce, as it stops those multiple events caused by the physical contacts in the button bouncing together and apart. I tend to use 50 (milliseconds) as a reasonable start value.

  • @Gordon Thanks for the feedback.

    I have check but a strange behavior in puck. I am getting events for some other pins. I have setWatch for button but got event for Pin D0

    { "lastTime": 859.655, "time": 859.96, "pin": D0, "state": false }

    how should we handle this. Please suggest.

  • Hi - that's to be expected - the button is actually connected to pin D0 - so BTN == D0. It's just that when you print it, Espruino chooses to print D0 and not BTN to the screen

  • @Gordon i am getting some issue which i am trying to handle. On my clients PuckJS it is so sensitive that even when puck is moved its event it getting triggered. But on my end its not that sensitive.

  • Has your client updated to the 1v92 firmware? That could be an issue

  • Can you share us the link how to do this.

    Type process.version on the LHS of the Web IDE to check

  • Thanks @Gordon
