Which version of the ESP8266 hardware board definition package should I be using? I've tried several recent releases, and all result in these compile errors: Arduino: 1.6.4 (Mac OS X), Board: "Generic ESP8266 Module, 80 MHz, 115200" Build options changed, rebuilding allUsing library ESP8266WiFi in folder: /Users/accountholder/Documents/Arduino/hardware/esp8266com/esp8266/libraries/ESP8266WiFi Using library Blynk in folder: /Users/accountholder/Documents/Arduino/libraries/blynk-library-master.


Arduino IDE Becomes More Open, Less Snarky. Version 1.6.4 of the Arduino IDE has been out for a little while now, and it has a couple of notable changes. To our eyes, the most interesting change makes adding support for non-standard boards and their configurations within the Arduino IDE a lot simpler. We’ll get into details below. But before that, it’s time to bid farewell to the cheeky little popup window that would deliver a warning message when using a board bearing the USB IDs of their former-partner-turned-competitor. We absolutely agree with [Massimo] that the issues between Arduino SRL / Smart Projects and Arduino LLC are well-enough known in the community, and that it’s time for the popup to fade away. Now on to the meat of this post.

The new “Board Manager” functionality makes it significantly easier for other non-Arduino products to be programmed within the Arduino IDE. The list of unofficially supported third-party boards is still a bit short, but it includes some stellar entries. Servidor Web con WIFI ESP8266 | Tutoriales Arduino.

Material requerido. Mas sobre WIFI y ESP8266 En las dos últimas sesiones hemos estado jugando con el módulo WIFI ESP8266. Le he encontrado muy simpático y capaz, especialmente dado su bajo precio. Le hemos probado primero alimentado directamente desde el Arduino, lo que no es muy aconsejable dado que, especialmente en el arranque, puede demandar más intensidad de la que el pin de 3V puede proporcionar.

En la siguiente sesión usamos una fuente de alimentación de protoboard para garantizar la alimentación correcta del módulo, lo que nos llevó a un arranque falible al 100% (Menos mal). Pero aun así, seguíamos usando las señales de transmisión de Arduino a 5V sin adaptar a los 3,3 V que el fabricante recomienda. El programa de control.

This should be a familiar device to most of you. This is the Arduino. It is an excellent tool for introduction to the embedded world. The Uno will probably be the most familiar sight. It is powered by the Atmel made ATMega328 MCU. The one shown above is the Arduino Mega which uses the ATMega2560. If you've never used an Arduino before now, play with it a bit. If you have a different microcontroller that you like more (TI Launchpad or PIC32 for example) the same principles will apply to using them. ESP8266 Wifi with the Arduino Micro. A few months ago a new board called the ESP8266 arrived on the scene and promised a very cheap way for serial devices (such as the Arduino) to to make HTTP requests. The device itself was less than $10 (I got a few on AliExpress for $5) and it meant that smart microcontrollers could be easily made into “Internet of Things” devices.

The boards (from the factory) operate at 115200, and that is just too fast for SoftwareSerial, so I decided to use and Arduino Micro to play around with it. The Arduino Micro has two serial ports so that it can communicate over USB (for debugging) as well as communicate over another serial channel (Serial1). This mean that I could use the Arduino Micro as a serial pass-through device and communicate with the ESP8266 directly. The annoying part was the 8 pin setup was not very breadboard friendly, so I de-soldered the back row of pins (GND, GPIO1, GPIO2, RX) and attached external wires so that they would work easier on a breadboard.

Home Control 2015 | Scargill's Tech Blog. Introduction (Latest update 22/JUNE/2015) If you’ve read my early blogs you’ll know I do a lot of work with a pal of mine, Aidan Ruff. We had an R&D company for years and one of our products was a home control system which achieved much coverage in the UK tech press at the time and many loved it but the design involved spouse-unfriendly WIRES – bad mistake. Well, this DOESN’T. The two of us have been working on home control for several years and regular readers will know that recent months, the ESP8266 boards have turned everything upside-down.

Armed initially with a WIFI USB dongle but now hardwired to Ethernet after experience of WIFI losses on the Pi2, the basics of a completely wireless home control setup are now in place. There are a number of variations on the ESP8266 boards, one popular item being the ESP-01 – a simple board with power, a couple of IO lines and serial in and out.

Auto ESP8266 Server Init | PetesTechProjects. The Plan Now that I have a pretty stable HW setup, I want to start automating things and automate controls over Wifi. The first step is to be able to auto init the ESP8266 whenever my system is power up or reset. Implementation The ESP8266 is able to store the last Wifi network configuration and rejoins the last Wifi access point that it was on each time it power up or is reset. I am going to assume that the ESP8266 is set up to attach to my Wifi router for now. Will come back and implement a way to set it up if moving to a new area later.

So assuming the ESP8266 is already on the Wifi network, I need to give the following commands…. AT+RST // Reset the module AT+GMR // Just a sanity check that the ESP8266 is responding AT+CIPMUX=1 // Set up for multi connections AT+CIPSERVER=1,8888 // Start up the server on port 8888 For each of these commands, I want to wait for the correct response from the ESP8266. The blinking code that I want to implement is… SW Implementation Testing Like this: ESP8266 Community Forum View topic - Arduino webserver - connect to wifi (AT commands)

ESP8266 Wifi information lcd. This is a little project I did in about 2 hours. It uses an LCD display I got from an old ISDN phone and shows text sent to it over WiFi.The ESP8266 runs a webserver which shows a form that can be used to set the text. After the ESP8266 receives the text it sends the text to an Arduino using the serial port. The Arduino then shows the text on the lcd. The biggest goal was to make the device as small as possible, by placing all the components directly on the lcd's circuit board I managed to make the circuit only a couple of millimetres higher than the height of the clips of the lcd bezel. (The display is an Optrex dmc50652n lcd) If anyone is interrested in the source code of the esp8266 and arduino firmware please let me know. New-AI-v0.9.5.0 AT Firmware.

A New Software Serial Library for Arduino News: NewSoftSerial is in the core! Starting with Arduino 1.0 (December, 2011), NewSoftSerial has replaced the old SoftwareSerial library as the officially supported software serial library.

This means that if you have 1.0 or later, you should not download this library. To port your code to 1.0, simply change all NewSoftSerial references to SoftwareSerial. NewSoftSerial is the latest of three Arduino libraries providing “soft” serial port support. It’s the direct descendant of ladyada’s AFSoftSerial, which introduced interrupt-driven receives – a dramatic improvement over the polling required by the native SoftwareSerial. Without interrupts, your program’s design is considerably restricted, as it must continually poll the serial port at very short, regular intervals.

Improvements NewSoftSerial offers a number of improvements over SoftwareSerial: *But see below for an important caveat on multiple instances. Using Multiple Instances Signal Inversion. Esp8266_firmware_update [UKHASnet Wiki] Before using the ESP8266 module, the firmware needs to be updated to provide wider router support. The instructions shown below are based on my experiences whilst upgrading my ESP8266 modules to firmware version Preparation Connect your ESP8266 module as follows: Vcc = 3.3V (needs around 300-400mA peak) Gnd = -ve ground CH_PD = Chip enable so always +ve RST = Leave floating or ground to reset GPIO0 = Normally floating but this needs to be grounded when you start the update.

You also need to download the new firmware and update tool from ElectroDragon: The firmware tool is called XTCOM Before you start the update, make sure your ESP8266 is working normally as follows: Connect-up as above but leave GPIO0 floating. If all is well, you can move on to the firmware update. Firmware Update Windows Here are the steps required to update the firmware: Put the ESP8266 into firmware update mode by grounding GPIO0 and re-cycling the power. Linux or OS X Testing Next Steps.

Squix TechBlog: ESP8266: flashing the lua firmware and running some code. After you setup your ESP8266 module as described here you can go on and write Arduino code that talks to the ESP8266 or even flash new firmware directly on the device.

Someone has put together a firmware which allows you to send lua code to the module and run it through the serial console. This is a nice way to get started with programming the module directly instead of using an Arduino intermediary. This post describes how you can flash a new firmware on the module. Getting the wiring right Make sure you already have the wires setup as described in the previous post. Add a wire between GPIO0 pin and the Ground pin (GND)Now reset the module be quickly connecting the RST pin to the GND pin (in my case the blue LED flashes quickly) Getting the flash tool ready In order to write new firmware to the module you'll need to use a tool, the serial console isn't helpful in this case. Download the from here. Running Lua examples on the module Update 2015-01-04 Links Advertisement: Esptool raspberry pi. Raspberrypi:getting_started [ESP8266 Support WIKI] There are a number of different modules that all feature the ESP8266EX chip - some that have been numbered ESP-01 to ESP-12 as well as others, and new ones are being made all the time.

Requirements ESP-01 Raspberry Pi A+ or B+ ESP-01 module looks like this (ensure you have later version with chip marked ESP8266EX): And we'll be using a Raspberry Pi running Raspbian operating system to talk to the module. As well as these two boards you'll need something to connect them together - ideally some female to female jumper cables.

So - if you only have a model A or B then you'll need to find another way to power the module. Wiring OK so assuming you've got a newer model A+ or B+, attach the pins of the Raspberry Pi to the ESP-01 module like this: So to summarize - that's VCC to 3.3v on the Pi, ground to ground, Tx to Rx and Rx to Tx, and connect the CH_PD (Chip Power Down) to VCC to disable the chip power down and make it power up! Communication Congratulations - you've connected to the module! A world of MQTT on ESP8266. ESP8266 update firmware to change the baudrate | ReiLabs | Page 2. So today I figured I could update firmware on my ESP8266 to make it useful for work with the arduino uno. The problem with the original firmware is that the serial port baudrate is fixed at 115200 which is way too fast for the softserial library and even too fast for uno’s normal serial port to be reliable.

The new firmware supposedly features adjustable baudrate and also a few bug fixes. First you need to prepare yourself for the firmware upgrade. Download the firmware update tool and the latest firmware binary. Both files can be found on this page. (You may also use arduino as both the power source and USB-serial converter, I have used it in my previous posts as a power source. The connection for the flashing is slightly different than the normal connection. Connections to be made: PSU GND – ESP8266 GPIO0 (should be connected for flashing operation) I suggest you to connect everything before powering up to prevent damage to the module.
