Debouncing issues with setWatch();

Firmware 1v79

I have a noisy button on B5.

The default debounce setting (10ms) per setWatch() docs doesn't seem to do anything. When I add debounce: 20 (or any value), it prevents the callback from getting any args. Code below.

Recommendations?

var button=B5;
pinMode(button, 'input_pulldown');
function buttonPressed(info) {
        console.log(info);  // [ undefined ]
        info.time;   // Uncaught Error: Field or method "time" does not already exist, and can't create it on undefined
}
setWatch(buttonPressed,button,
         {repeat:true,debounce:200});

Interesting - thanks. That looks like a regression - I'll create a bug for it and will see if I can get it done for the next release.

When you're using debounce you're not going to get a very accurate time anyway though given all the bouncing. In this case, why not just use the getTime() function?

Granted getting button state is more of a pain, but the best bet for now is just to use digitalRead(button) as the watch will only have been called if the button state has been stable for a while.

Fixed now, it'll be in the 1v80 release. Available from http://www.espruino.com/binaries/git/commits/03bc4de4ed9fee0a7863c0e55040ad79f2a2fa35 in a few minutes
