Is there a cheap temperature sensor that can handle up to 350°C to adjust this station ?

this is offered in Germany at LIDL solder station
will get one and come back with test results ...

to avoid shadows use three led stripes and put them on a carrier, this should create a nice all-over sword light

seems like this is getting a big boy toy ;-)

in file ESP8266_BOARD.py ?

Is someone getting a valid build for USE_GRAPHICS=1 ?

mine is lost in reset loops...

also check this ESP12 shifter from adafruit

what about the wifi setup code ?

try this

var http = require("http");
http.createServer(function (req, res) {
  res.writeHead(200);
  res.end("Hello World"); 
}).listen(8080);
save();

use load(); to get your code back and then use dump(); to display saved code

updated to work with 1v84.tve

I use the IDE as chrome APP and set up a project,
this allows me to add local modules in the project folder modules.
Send to Espruino will include this modules than save() and check with dump()

@tve: no wires, what about the very first time after unboxing the ESP ?

take a look at this test results with different pull up resistors

http://dsscircuits.com/articles/effects-­of-varying-i2c-pull-up-resistors

@tve I like the idea : start "ap" when "sta" fails by default !

ignore this, cannot produce anymore

mode is changing when changing phy and powersave like this ?!

what about

// event Wifi.dhcp_timeout() ? what fires that one ?

try to test save("clear") and restore()

Wifi.save("clear");
resert();
........
var Wifi = require("Wifi");
Wifi.restore();
Wifi.getStatus();
={
  "mode": "off",
  "station": "off",
  "ap": "disabled",
  "phy": "11g",
  "powersave": "none",
  "savedMode": "off"
 }
Wifi.getDetails();
={
  "status": "off",
  "ssid": "mySSID",
  "password": "myPassword",
  "savedSsid": null }
>Wifi.getAPDetails();
={
  "status": "disabled",
  "authMode": "wpa2",
  "hidden": false, "maxConn": 4,
  "ssid": "ESP001",
  "password": "esp00001",
  "savedSsid": null }
> 

so it clears the overall wifi configuration and keeps station and access point configuration.
Is that what you implemented for "clear" ?

you can list your saved code by using dump();

>dump();

and than check for the error.

got further, just connected and mode switches to "sta+ap"

this works fine

Wifi.getHostByName("bbc.co.uk", function(params){
:      fn="Wifi.getHostByName()";
:      console.log(fn+" params:" + JSON.stringify(params)); // Tested OK
:    });
=undefined
Wifi.getHostByName() params:"212.58.244.22"

and this dumps

> Wifi.getHostByName("bbc.co.ukk", function(params){
:      fn="Wifi.getHostByName()";
:      console.log(fn+" params:" + JSON.stringify(params)); // Tested ERR
:    });

I do it like this:

}
E.on("init",start);
save();

starting some tests, hit by this: cannot change the mode... stuck in mode = ap

>var Wifi = require("Wifi");
>Wifi.getStatus();
={
  "mode": "ap",
  "station": "off",
  "ap": "enabled",
  "phy": "11n",
  "powersave": "ps-poll",

  "mode": "ap",
  "station": "off",
  "ap": "enabled",
  "phy": "11n",
  "powersave": "ps-poll",
  "savedMode": "off"
 }

mode is changing when changing phy and powersave like this ?!

>var Wifi = require("Wifi");
>Wifi.setConfig( {phy : "11g",powersave : "none"} );
>Wifi.getStatus();
={
  "mode": "sta+ap",
  "station": "off",
  "ap": "enabled",
  "phy": "11g",
  "powersave": "none",
  "savedMode": "off"
 }

@tve I can run some tests as well, any specific things or the whole wifi ?

got one :-)

3f is the GIPO extender and 7f is the eeprom.

pi@rpi001 ~ $ i2cdetect -a -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3f

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 7f 

to change the address ground the Ax ports.
A0 to ground will change the address to 3e and 7e

Seems like a simple I2C2.writeTo(addr, my8databits) would set the outputs, I2C2.readFrom(addr,1) would read them.

can confirm that, tried with i2cset and i2cget.

next step do some i2c test in espruino.

get you mac in : stlye

>var wifi = require("wifi");
=function () { [native code] }
>wifi.getIP().mac;
="5c:cf:7f:05:9a:33"

and wifi.scan lists the AccessPoints

>wifi.scan(function(e,arrayOfAcessPoints­) {
:  if ( arrayOfAcessPoints != null) {
:    for (var i=0; i<arrayOfAcessPoints.length; i++) {
:      print("Access point: " + i + " = " + JSON.stringify(arrayOfAcessPoints[i]));
:  }} else{print("no Access points found"); }});
=undefined
Access point: 0 = {"rssi":-45,"channel":1,"authMode":3,"is­Hidden":false,"ssid":"SBITUmts"}
Access point: 1 = {"rssi":-63,"channel":11,"authMode":4,"i­sHidden":false,"ssid":"SBIT"}
Access point: 2 = {"rssi":-85,"channel":11,"authMode":4,"i­sHidden":false,"ssid":"SBIT"}

many thanks to those who added and fixed it.

@user59035 is this the board you are using ?
http://www.14core.com/wp-content/uploads­/2015/06/Node-MCU-Pin-Out-Diagram1.png

this is what I find helpful for now :

//Soft Reset        
reset();
//Details
print("mem:"+JSON.stringify(process.memo­ry())+",version:"+process.env.VERSION+",­git_commit:"+process.env.GIT_COMMIT);
//WiFi Status
var wifi=require("Wifi");wifi.getStatus();
//Hard Reset
var esp=require("ESP8266");esp.reboot();

let me know what you use

looks like that in the EDI
