thanks for your suggestion, this is the output

Uncaught Error: Function "setTimeByUrl" not found!

jt.setTimeByUrl('http://www.espruino.com', 1, console.log);

in function called from system

The plan is to write a module and include it in custom build with JSMODULESOURCES to have all nice tools in place without wasting time on load.

Starting with a time helper as sample, I was fiddling around and have no clue how to write a working module. Any suggestions how to make this work?

// module code  jstools.js

var jstools = function (){};

jstools.prototype.setTimeByUrl = function(url,tz,callback) {
	require('http').get(url, function(res){
    	var date = new Date(res.headers.Date);
    	if (date > 0 ) {
      		setTime(date/1000);
      		E.setTimeZone(tz);
      		error = null;
    	} else {
      		error = 'no date';
  		}
  		if (callback)
  			callback(error);
	});
};

exports = jstools;

// test code 
var jstools = require('jstools');

setTimeout(function(){
  jstools.setTimeByUrl('http://www.espruin­o.com',1,function(e){console.log(e);});
},1000);

//output 
Uncaught Error: Function "setTimeByUrl" not found!

check this page too , it also explains how round the grabbed values.

Uncaught InternalError: I2CWrite: No ACK 0

Make sure you connected SDA and SCL to the pins you use.

Just to recap:

steps you did to get a stable Espruino:

• erase flash

• flash files from dir espruino_1v95_esp8266_4mb with flash_size 4mb-c1

Wifi stuff:

Wifi.connect(SSID, {password:SSIDPASS}, function(err){
  if (err === null){
    console.log('Connected to AP');
    Wifi.stopAP();
    Wifi.setConfig({powersave : 'none'});
    Wifi.save();
  } else {
    console.log('connetion error',err);
  }
});

I am interested in output of console.log('connetion error',err);

there are now some updates on the ESP8266 page - check section Build Content

This is the reason you have to run a extra neopixel.write() command:

Every time you upload with reset some extra pinMode commands are included:

>reset()

This is very helpful, because you always start with the same defined pinMode for all pins.

I suggest to include a pinMode() for pins you use different.

var neo = require("neopixel");
var neoPin = NodeMCU.D4;  // D2
pinMode(neoPin,'output');
neo.write(neoPin, [25, 0, 0]);  // 255 is to bright for me :)

Ups, mixed it up - sorry .....

Analog input on ESP8266 a very poor, but you can try.

There is a module for the MQ135 Air Quality Sensor , might be a good starting point.

Hi, check this link and try this sample.

If this works for you, please add your test code and some comments - if you like :)

After upload and starting some function manually, I got this message on a ESP8266 device.

Otherwise it is possible to turn on hardware flow control for the ESP8266. It's something I haven't enabled by default yet, but we could try that?

How to enable and try this hardware controll?

To be honest, I was thinking about adding it to GRAPHICS as option and call it like this:

Graphics.createArrayBuffer(16,16,24, {panelMap:[[0,64],[56,120]]})

Thanks for you test and feedback.

Does is reconnect to the AP after require('ESP8266').reboot() ?

A 4mb build has more save pages

16 versus 3

Only espruino_1v95_esp8266_combined_512.bin does,

start with esptool.py --port /dev/ttyUSB0 --baud 115200 erase_flash and then follow
conversations http://forum.espruino.com/comments/14055­829/

Paul is writing to offset 2 eeprom.write(2,[55,99]), I also missed this on first sight :)

Hi @user85573,

can you please share output of esptool.py --port /dev/ttyUSB0 --baud 115200 flash_id as 16MB is missing on my list of ids.

W25Q40BV ( 4 Mega Bits / 512K Byte ) = ID 4013h
W25Q80BV ( 8 Mega Bits / 1 Mega Byte ) = ID 4014h
W25Q16BV ( 16 Mega Bits / 2 Mega Bytes ) = ID 4015h
W25Q32BV ( 32 Mega Bits / 4 Mega Bytes ) = ID 4016h
W25Q64CV ( 64 Mega bits / 8 Mega Bytes ) = ID 4017h

Edit:
Ups missed than on your post manuf 0xef chip 0x4018

so it is

W25Q128FV ( 128 Mega bits / 16 Mega Bytes ) = ID 4018h

DS1307 and AT24C32 on TinyRTC

• integrated 3.73 pullups
  
• used module DS3231 - work perfect with DS1307
  

• tested on ESP8266-04,12E/F 1v95

  var SDA = D5, SCL = D4; // ESP8266
  I2C1.setup({scl:SCL,sda:SDA, bitrate:100000});
  
  var rtc = require("DS3231").connect(I2C1, { DST : true });
  rtc.setDate(Date().getDate(),Date().getM­onth(),Date().getFullYear());
  rtc.setTime(Date().getHours(),Date().get­Minutes(), Date().getSeconds());
  
  setInterval(function() {
  console.log(rtc.readDateTime());
  }, 1000);
  
  /* output

Thanks Gordon, will test this later

As you have a 4016 chip which is 4MB of size, you can try those files:

http://www.espruino.com/binaries/espruin­o_1v95_esp8266_4mb/

esptool.py --port /dev/tty.SLAB_USBtoUART --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB-c1 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin

Yes, of course, see the new version of the REAMDE.txt

Is wifi.save() no working for you?

Take a look at Flash storage Module, any js type , web pages, css, js and images by Wilberforce

let esptool.py figure out your flash size

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

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

W25Q40BV ( 4 Mega Bits / 512K Byte ) = ID 4013h
W25Q80BV ( 8 Mega Bits / 1 Mega Byte ) = ID 4014h
W25Q16BV ( 16 Mega Bits / 2 Mega Bytes ) = ID 4015h
W25Q32BV ( 32 Mega Bits / 4 Mega Bytes ) = ID 4016h
W25Q64CV ( 64 Mega bits / 8 Mega Bytes ) = ID 4017h
