# Espressif IoT Development Framework

* [中文版](./README_CN.md)

ESP-IDF is the development framework for Espressif SoCs supported on Windows, Linux and macOS.

# ESP-IDF Release Support Schedule

![Support Schedule](https://dl.espressif.com/dl/esp-idf/support-periods.svg?v=1)

- Please read [the support policy](SUPPORT_POLICY.md) and [the documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) for more information about ESP-IDF versions.
- Please see the [End-of-Life Advisories](https://documentation.espressif.com/en/documentList?qr=End-of-Life&eol=true) for information about ESP-IDF releases with discontinued support.

# ESP-IDF Release and SoC Compatibility

![Chip support](https://dl.espressif.com/dl/esp-idf/chip-support.svg?v=1)

See [Compatibility Between ESP-IDF Releases and Revisions of Espressif SoCs](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY.md) for the details of the compatibility between ESP-IDF and chip revisions.

Espressif SoCs released before 2016 (ESP8266 and ESP8285) are supported by [RTOS SDK](https://github.com/espressif/ESP8266_RTOS_SDK) instead.

# Developing With ESP-IDF

## Setting Up ESP-IDF

See https://idf.espressif.com/ for links to detailed instructions on how to set up the ESP-IDF depending on chip you use.

**Note:** Each SoC series and each ESP-IDF release has its own documentation. Please see Section [Versions](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) on how to find documentation and how to checkout specific release of ESP-IDF.

### Non-GitHub forks

ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub. If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.

The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete. If cloning ESP-IDF from GitHub, this step is not needed.

## Finding a Project

As well as the [esp-idf-template](https://github.com/espressif/esp-idf-template) project mentioned in Getting Started, ESP-IDF comes with some example projects in the [examples](examples) directory.

Once you've found the project you want to work with, change to its directory and you can configure and build it.

To start your own project based on an example, copy the example project directory outside of the ESP-IDF directory.

# Quick Reference

See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects:

## Setup Build Environment

(See the Getting Started guide listed above for a full list of required steps with more details.)

* Install host build dependencies mentioned in the Getting Started guide.
* Run the install script to set up the build environment. The options include `install.bat` or `install.ps1` fo
