waveform and setInterval issue...

Ahh - that's interesting. Looks like there are 2 issues (Which I should have checked!)

• If you make a Uint16Array with everything the same value and then sort it, sort crashes(!) Uint8Array works fine though, and strangely it also works on a Pico! I've just filed a bug for this.
  

• We need to set a longer interval. As we do all out calculations first, and then kick off the Waveform, the waveform isn't finished by the time the interval fires again. I've just increased the interval to 200ms and that's fixed it.

  var w = new Waveform(128/* your buffer size */,{doubleBuffer:false, bits:16});
  
  var first = true;
  setInterval(function() {
  if (!first) {
  var myarr = w.buffer;
  myarr.sort();
  // cut off first and last 2 elements
  var view = new Uint16Array(myarr.buffer, 2/*sizeof(uint16)*/*2, myarr.length-4);
  var vOut = E.getAnalogVRef() * E.sum(view)/(view.length*65536); // if you attached VOUT to Ao
  var vZero = 0.4;
  var tCoeff = 19.5 / 1000;
  var tempinc = (vOut - vZero) / tCoeff;
  var tempinf = tempinc * (9 / 5) + 32;
  console.log("Temp in C: " + tempinc);
  console.log("Temp in F: " + tempinf);
  //console.log(E.sum(view)/(view.length*65536));    
  } else first = false;
  // start it again
  w.startInput(A0,2000 /* Samples per second */);
  }, 200);
