  Thank you for the hints. I will keep to work on it in the next weeks, since it is part of my research project at university. I will try to follow your advice. HW initializing twice is an error, I just copied it twice. Thank you again for your efforts!

  Hi Robin, thank you again for your help. I completely understand you, there is no need to apologize. I will try to make a landing page over the weekend.

  Hi allObject, I worked on it today and I made it working using your logic. I changed something on the code, but nothing relevant. I needed a bit of troubleshooting, but your help was essential. Thank you very much!

  I attach the final version of both library and main code, it may be helpful for someone else.

  var sensor1;
  var I2C1 = new I2C();
  var sensor1IID;
  
  function initHW(){
    digitalWrite(D31, 0);
    I2C1.setup({sda:D1, scl:D2, bitrate:400000});
  }
  
  function initSensor(){
    console.log('Initialazing sensor');
    digitalWrite(D31, 1);
    sensor1 = require("https://github.com/SalvoCas/Esp­ruinoDocs/blob/master/devices/VL6180X.js­").connect(I2C1, {address:0x29});
  }
  
  function doStart(){
    initHW();
    initHW();
    initSensor();
    var status = sensor1.readRangeStatus();
    if (status==0){
    setTimeout(function(){
      sensor1IID = setInterval(function(){
        sensor1.readRange(function(err,val){
          if(err){
            console.log("ModuleError:", err, " - DeviceError:", val);
          }
          else{
            console.log("Sensor 1: ",val,"mm");
          }
        }); },200);
      },1);
    }
    else{
      console.log("Err status: ", status);
    }
  }
  function onInit(){
    doStart();
  }
  
  setTimeout(onInit, 999);

  HI Robin, sorry for my lack in information. Right now I am using the breakout board of the module VL6180X by Adafruit (https://www.adafruit.com/product/3316). I am using the puck.js board, the wiring is as follow:

  • SDA to D1
    
  • SCL to D2
    -GPIO0 to D31
    -Power to 3V
    -Ground to GND
    They are directly connected, since the breakout board should allow it. The wiring seems to be correct, since I made it working and I checked them using the multimeter.
    
    

  The result of the command process.env is:

  >process.env
  ={
    "VERSION": "1v99",
    "GIT_COMMIT": "f0d66ba",
    "BOARD": "PUCKJS",
    "FLASH": 524288, "RAM": 65536,
    "SERIAL": "6ddd0f13-64ec2540",
    "CONSOLE": "Bluetooth",
    "MODULES": "Flash,Storage,net" ... "S,crypto,neopixel",
    "EXPTR": 536882352 }
  

  I believe that the hints given by allObjects can lead me to write a right code. It is my first project using the Espruino IDE and I am totally new to JavaScript, therefore I wrongly approached the problem as I was working with Arduino or any C-based processor.
  Thank you for your help and I again apologize if I have been shallow in my previous posts.

  Thank you so much! I really appreciate your help. In someway I made it working using the previous code I showed you, but it is quite unstable and it still yields to errors after a while. In the next days I will implement a code using your logic. I actually had no experience using promises, but I tried to study them yesterday, I will go into more details and try to implement a version of the code using this approach. Thank you again!

  Yes, I am talking about this error.

  I agree with you, but I could not find the error on the library I wrote. I will keep looking at it, thanks!

  Thanks for the help. I changed my code in this way, but I still have the overflow error. I do not really know why there is still this error, since the module works perfectly fine with Arduino, whit a library having the same logic flow of the one I built for Espurino.

  var sensor1;
  var I2C1 = new I2C();
  
  function onTimer() {
    var l1 = sensor1.readRange();
    console.log("Sensor 1: "+ l1 +" mm");
  }
  
  function initHW(){
    digitalWrite(D31, 0);
    I2C1.setup({sda:D1, scl:D2, bitrate:400000});
  }
  
  function initSensor(){
    console.log('Initialazing sensor');
    digitalWrite(D31, 1);
    sensor1 = require("https://github.com/SalvoCas/Esp­ruinoDocs/blob/master/devices/VL6180X.js­").connect(I2C1);
  }
  
  function doStart(){
    initHW();
    initSensor();
    setTimeout(function() {}, 1);
    var status = sensor1.readRangeStatus();
    if(status == 0){
      setInterval(onTimer, 500);
    }
    else{
      console.log('Error number: '+ status);
    }
  }
  
  function onInit(){
    doStart();
  }
  
  setTimeout(onInit, 999);

  Thank you! I will definitely look into it.

  Thank you for your help! It's the first time I code for Espruino and I still need to get used to it. I had concern about the loop functions, since I thought that the way they work is quite different from the environment I used to work in (especially Arduino). I will try to change my code according to your suggestions, thank you!
