This project brings support for ESP8266 chip to the Arduino environment. It lets you write sketches using familiar Arduino functions and libraries, and run them directly on ESP8266, no external microcontroller required.
ESP8266 Arduino core comes with libraries to communicate over WiFi using TCP and UDP, set up HTTP, mDNS, SSDP, and DNS servers, do OTA updates, use a file system in flash memory, work with SD cards, servos, SPI and I2C peripherals.
Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).
- Install Arduino 1.6.5 from the Arduino website.
- Start Arduino and open Preferences window.
- Enter
http://arduino.esp8266.com/stable/package_esp8266com_index.jsoninto Additional Board Manager URLs field. You can add multiple URLs, separating them with commas. - Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
The best place to ask questions related to this core is ESP8266 community forum: http://www.esp8266.com/arduino.
If you find this ESP8266 board manager useful, please consider supporting it with a donation. The ESP8266 Community Forum and IGRR have made this wonderful port available.

cd esp8266/tools
python get.py- Restart Arduino
Documentation for latest development version:
If you encounter an issue, you are welcome to submit it here on Github: https://github.com/esp8266/Arduino/issues. Please provide as much context as possible: version which you are using (you can check it in Boards Manager), your sketch code, serial output, board model, IDE settings (board selection, flash size, etc).
For minor fixes of code and documentation, go ahead and submit a pull request.
Larger changes (rewriting parts of existing code from scratch, adding new functions to the core, adding new libraries) should generally be discussed in the chat first.
Feature branches with lots of small commits (especially titled "oops", "fix typo", "forgot to add file", etc.) should be squashed before opening a pull request. At the same time, please refrain from putting multiple unrelated changes into a single pull request.
