PuckJS button event issues.

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

setWatch();

Code which i am using is as followed. Please

   setWatch(function(){
},BTN,{edge:"rising",repeat:true});

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.

setWatch(function(){
},BTN,{edge:"rising",repeat:true,debounce:50});

@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
