  wow, thank you! :)

• DH22: Unable to set watch

  I had the same. The only PIN it works was G0. But as I learned today, there are issues with the DHT22 and the setWatch which causes some weird crashes of my ES32.

  Ah okay :) Sorry! I guess I have to switch to another solution in the meanwhile. But that projects is very promising!

  You mean this issue on github? https://github.com/espruino/Espruino/issues/643

  Is there any ETA to fix this?

  Hey guys,

  thank you for this great project! Currentyl I'm just playing around with some sensors with my ESP32. I'm pretty new to microcontrollers.

  I just got a SSD1306 working with espruino on my ESP32, it works flawless. Yesterday I had to connect a DHT22 and my ESP32 keeps crashing after a few measurements of the temp. This code isn't that spectacular, but I really don't know why its crashing. I always get that message:

  WARNING: jshI2CSetup: driver installed, sda: 21 sdl: 22 freq: 50000,

  After the core dump I see:

  It doesn't matter how often I read the DHT. It crashes after two measurements and after none.
  The DHT is connected to GPIO15 with a pullup resistor (10k). It keeps crashing even without WiFi and a webserver. You can see my wiring (without the oled) attached.

  My code:

  I2C1.setup({scl:D22,sda:D21});
  var g = require("SSD1306").connect(I2C1, start,{
    contrast: 255 
  });
  
  require("FontDennis8").add(Graphics);
  g.setFontDennis8();
  
  function start(){
    log("Booting up...");
    var ssid = "SSID";
    var pw = "PW";
    
    readTemp(D15);
    
    if(connectWifi(ssid, pw)){
     if(startWebserver(8080)){
        log("Let's get started!"); 
     }  
    }
  }
  
  function connectWifi(ssid, password){
    var wifi = require('Wifi');
    //wifi.setHostname("Disane_ESP32");
    var ip = wifi.getIP().ip;
    if(ip != "0.0.0.0" && ip){
      log("IP: "+ip);
      return true;
    }else{
      wifi.connect(ssid, {password: password}, function(err) {
        if (err) {
          log("Connection error: "+err);
          return false;
        }
        log('Connected to Wifi: '+ ip);
        //wifi.save(); // Next reboot will auto-connect
        return true;
      });
    }
  }
  
  function startWebserver(port){
    log("Starting Webserver...");
    var http = require("http");
    http.createServer(function (req, res) {
      res.writeHead(200);
      res.end("Hello World");
    }).listen(port);
    return true;
  }
  
  
  function readTemp(pin){
    
    //log("Reading temp and RH");
    //pinMode(D15, input_pullup);
    var dht = require("DHT22").connect(pin);
    setInterval(function(){
      dht.read(function (a) {
        if(a.err){
          log("Error | checksumError: "+a.checksumError);
        }else{
          log("Temp: "+a.temp.toFixed(2).toString()+"°C | RH: "+a.rh.toFixed(2).toString()+"%", 8);
        }
      });
    },5*1000);
  }
  
  
  
  function log(text, fs = 5){
    g.clear();
    console.log("["+Date.now() +"]: " +text);
    //g.setFontVector(fs);
    g.drawString(text,2,2);
    // write to the screen
    g.flip();
  }
  

  Does anybody of you have a clue?
