espressif / esp-idf

# Espressif IoT Development Framework
* 中文版
ESP-IDF is the development framework for Espressif SoCs supported on Windows, Linux and macOS.
# ESP-IDF Release Support Schedule
- Please read the support policy and the documentation for more information about ESP-IDF versions.
- Please see the End-of-Life Advisories for information about ESP-IDF releases with discontinued support.
# ESP-IDF Release and SoC Compatibility
See Compatibility Between ESP-IDF Releases and Revisions of Espressif SoCs 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 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 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). 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 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 project mentioned in Getting Started, ESP-IDF comes with some example projects in the 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` for Windows, and `install.sh` or `install.fish` for Unix shells.
* Run the export script on Windows (`export.bat`) or source it on Unix (`source export.sh`) in every shell environment before using ESP-IDF.
## Configuring the Project
* `idf.py set-target ` sets the target of the project to ` `. Run `idf.py set-target` without any arguments to see a list of supported targets.
* `idf.py menuconfig` opens a text-based configuration menu where you can configure the project.
## Compiling the Project
`idf.py build`
... will compile app, bootloader and generate a partition table based on the config.
## Flashing the Project
When the build finishes, it will print a command line to use `
