external button puckjs

Below is the code as described in post #2. The cycle starts over again after display has completed. Display is a series of blinking green and red blinking:

• green for every 10 seconds
  
• red for every second remaining
  

• very brief red flash for less then a second

  // puckD1extPushButton.js
  pinMode(D1,"input_pullup");
  var log = function() { console.log(arguments); }
  , lon = false // log on / off
  , blT = 200 // blinkTime (on and off time)
  , flT = 20 // flashTime (for less than a second pressed)
  , t0, t1
  , wIdD, wIdU
  , down = function() {
    if (wIdU) clearWatch(wIdU);
    wIdD = null;
    t0 = getTime();
    wIdU = setWatch(up,D1
             ,{repeat:false, edge:"rising",debounce:10});
  }
  , up = function() {
    if (wIdD) clearWatch(wIdD);
    wIdU = null;
    t1 = getTime();
    setTimeout(show,10,Math.floor(t1 - t0));
  }
  , show = function(t) {
    if (lon) log(t);
    if (t>10) {
      LED2.set();
      setTimeout(function(){
        LED2.reset();
        setTimeout(show,blT,t-10);
      },blT);
    } else if (t>0) {
      LED1.set();
      setTimeout(function(){
        LED1.reset();
        if (--t>0) {
          setTimeout(show,blT,t);
        } else{
          start();
        }
      },blT);
    } else {
      LED1.set();
      setTimeout(function(){
        LED1.reset();
        setTimeout(start,blT);
      },flT);
    }
  }
  , start = function() {
      wIdD = setWatch(down,D1
               ,{repeat:false, edge:"falling",debounce:10});
  }
  ;
  function onInit() {
  start();
  }
  
  setTimeout(onInit,999); // comment line before upload for save()
  

With a pretty decent - not much bouncing switch - there should be a much simpler solution... except for the display, which then gets a bit more complicated: results would have to be written to a queue and display would run asynchronously / simultaneously. To distinguish between flash/blink sequences, blue led could be flashed between the sequences.
