Thanks, so this will ensure that not messing up global vars with the same name.

analogReadMedian = function(p, sampleCount) {
      var i, median;
      var samples = Math.floor(sampleCount);
      var analogValues = new Array(samples);
      // read analog values into array
      i = samples;
      while(i--) analogValues[i] = analogRead(p);
      //sort array, smalest first and largest last
      analogValues.sort(function(a, b){return a-b;});
      // set median
      i = Math.floor(samples/2);
      if ( samples % 2 ){ //even
          median = (analogValues[i]+analogValues[i+1])/2;
      } else { // odd
          median = analogValues[i];

Thanks for naming the median filtering technic, using this now for several devices running Espruino. Works fine for me with sampleCount = 21.

analogReadMedian = function(p, sampleCount) {
      var samples = Math.floor(sampleCount);
      var analogValues = new Array(samples);
      // read analog values into array
      i = samples;
      while(i--) analogValues[i] = analogRead(p);
      //sort array, smalest first and largest last
      analogValues.sort(function(a, b){return a-b;});
      // set median
      i = Math.floor(samples/2);
      if ( samples % 2 ){ //even
          median = (analogValues[i]+analogValues[i+1])/2;
      } else { // odd
          median = analogValues[i];
      }
      return median;
};

can confirm that fix is working as expected

test snippet:

var Wifi = require("Wifi");
var i = 1;
var sleep = 7000;
setInterval(function(){
  console.log("run:",i++);
  Wifi.ping("192.168.194.1", function(rc){
    console.log("ping result",rc);
  });
  console.log("process.memory().free",proc­ess.memory().free);
},sleep);

@Gordon, thanks for checking and fixing it !

Throtteling is not used for Pico and EspruinoWifi (afaik), is there still a need to use it for ESPs when baud is set to 9600?

@Gordon is 9600 the transfer rate the IDE switch to when setting to slow communication?

Yes, lets switch to 9600.

looks like there is no etched onboard antena, what about the botton side?

You can search for howto attach a external wifi antenna if the is no etched.

What about grid with dots in the graph section

The led stand for the backlight ;-)

this is what I am working on:

Wow this sound great to me and I am a big fan of your resizable vector font as this is one of Espruino's unique features.

Like this very much about the new resizable font:

It uses half as much flash memory
You can choose the line width you want
It's faster to render when drawing single pixel width fonts

Well things always change.

What about: you keep g.setFontVector(s) and calculate the scaling factor to have a backward like compatibility as this could help not to mess up with the formatting of existing projects.

Try E.setTimeZone() to correct the time zone.

Yep, will use OpenSCAD and SVG would make things easier - Thanks in advance

I prefer a 3d printed one and will start a design be next week.

Hi @btrut

when I try to connect i reports no_ap_found (and list command to find ap's reports an empty array),

please make sure you use latest Wifi.scan() syntax

@Joshua_Sturmvogel

can you attach

• WEBIDE SETTINGS CONSOLE output
  
• WED IDE output while trying to connect
  
  

for further trouble shooting

Hi @Joshua_Sturmvogel,

check your flash_id and lookup your memory

esptool.py --port "$COMPORT" --baud 460800 flash_id

    Manufacturer: e0
    Device: 4016
    Detected flash size: 4MB

• get a new release of esptool.py
  
• read README_flash.txt which is part of the tgz file in comment #11
  
  

Hope this helps you to find the correct setting to flash your board.

mea culpa, how could I miss that 😳..... thanks to AntiCat

Hi SergeP,

as Gordon pointed out: Read the documentation first
there is no return for setTimeout()

Guess you are looking for setInterval().

Thanks for sharing

Add export RELEASE=1

Like to share how to write a module containing a class

// modules/stopWatch.js

class stopWatch {
      constructor() {
        var timeStart = 0;
        var timeStop = 0;
      }
    // Method start()
      start() { 
        this.timeStart = Date.now();
        this.timeStop = 0;
      }
    // Method stop()
      stop() { 
        this.timeStop = Date.now();
      }
      // Method duration()
      duration(){
        return this.timeStop-this.timeStart;
      }
}

exports  = stopWatch

and use it.

// projects/test_class_stopWatch.js

stopWatch = new (require('stopWatch'))();

function onInit(){
      stopWatch.start();
      setTimeout( function(){
        stopWatch.stop();
        console.log('duration in sec: ',
                ( stopWatch.duration() / 1000 ).toFixed(2) );
      }, 1000);
}

setTimeout(onInit,1000);

// output
duration in sec: 1.00
