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!

Hi Robin,

Thank you for your kind reply. Here it is the link to the complete documentation regarding the VL6180X module. In particular, I focused my study on the general datasheet:
https://www.st.com/resource/en/datasheet/vl6180x.pdf
and the technical notes about the range measurement: https://www.st.com/content/ccc/resource/technical/document/application_note/d5/bb/ec/94/7d/1e/40/a0/DM00122600.pdf/files/DM00122600.pdf/jcr:content/translations/en.DM00122600.pdf

This is the main code I am currently using:

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, {address:0x29});
}

function doStart(){
initHW();
initSensor();
setTimeout(function() {}, 1);
var status = sensor1.readRangeStatus();
if(status == 0){

setInterval(onTimer, 500);

}
else{

console.log('Error number: '+ status);

}
}

doStart();

The error I am encountering is a overflow error, specified by the RangeStatus number 15.
The espruino board I am using has the latest version on it.

Thank you for the help!

Hi everyone, I am using this sensor for my project. I looked at the libraries in internet and it seems that there is nothing targeting this module, therefore I write it by my own, following the structures of the libraries of two modules of the same family (VL53L0X and VL53L1X). My code is available on GItHub: https://github.com/SalvoCas/EspruinoDocs/blob/master/devices/VL6180X.js

Right now, I am using puck.js as board, but later I will use the MDBT42Q board. I am able to use the sensor on Arduino, but it is not working using the puck, so I think the problem is on the code I wrote. Still, I could not figure the problem out, so I am asking if anyone knows where is the problem.

I am having various issues. Firstly, the status of the sensor says that it goes on overflow, giving me 15 as error. Then, I tried to an if to control if the device is correctly read on the VL6180X function, but it is not.

Thanks to everyone that will take a look at it!
