This document is intended to help you set up the software development environment for the hardware based on the ESP32 chip by Espressif. After that, a simple example will show you how to use ESP-IDF (Espressif IoT Development Framework) for menu configuration, then building, and flashing firmware onto an ESP32 board. This is documentation for the master branch (latest version) of ESP-IDF. This version is under continual development. Stable version documentation is available, as well as other ESP-IDF Versions. ESP32 is a system on a chip that integrates the following features:

Powered by 40 nm technology, ESP32 provides a robust, highly integrated platform, which helps meet the continuous demands for efficient power usage, compact design, security, high performance, and reliability. This document is intended to help you set up the software development environment for the hardware based on the ESP32 chip by Espressif. After that, a simple example will show you how to use ESP-IDF (Espressif IoT Development Framework) for menu configuration, then building, and flashing firmware onto an ESP32 board. This is documentation for stable version v4.1.4 of ESP-IDF. Other ESP-IDF Versions are also available. ESP32 is a system on a chip that integrates the following features:

Powered by 40 nm technology, ESP32 provides a robust, highly integrated platform, which helps meet the continuous demands for efficient power usage, compact design, security, high performance, and reliability. ESP-IDF is the development framework for Espressif SoCs supported on Windows, Linux and macOS. 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. 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. This is the documentation for Espressif IoT Development Framework (esp-idf). ESP-IDF is the official development framework for the ESP32 chip. © Copyright 2016 - 2019, Espressif Systems (Shanghai) CO., LTD Revision f9108063. ESP-IDF requires some prerequisite tools to be installed so you can build firmware for supported chips. The prerequisite tools include Python, Git, cross-compilers, CMake and Ninja build tools.

For this Getting Started we are going to use the Command Prompt, but after ESP-IDF is installed you can use Eclipse Plugin or another graphical IDE with CMake support instead. The installation path of ESP-IDF and ESP-IDF Tools must not be longer than 90 characters. Too long installation paths might result in a failed build. The installation path of Python or ESP-IDF must not contain white spaces or parentheses. The installation path of Python or ESP-IDF should not contain special characters (non-ASCII) unless the operating system is configured with "Unicode UTF-8" support. It is recommended to set up the ESP-IDF development environment on Windows 10 or above.

You can download the installer from https://dl.espressif.com/dl/esp-idf/. The installer is also an open-source software, and its source code can be viewed at https://github.com/espressif/idf-installer. This installer is relatively small, around 4 MB in size, and other packages and code will be downloaded during the installation process. The advantage of the online installer is that not only can software packages and code be downloaded on demand during the installation process, but also allows the installation of all available releases of ESP-IDF... The disadvantage is that it requires a network connection during the installation process, which may cause installation failure due to network problems. This installer is larger, about 1 GB in size, and contains all the software packages and code required for environment set up.

The main advantage of the offline installer is that it can be used on computers without Internet access, and generally has a higher installation success rate. It should be noted that the offline installer can only install stable releases of ESP-IDF identified by v*.* or v*.*.*. After downloading a suitable version of the installer (take ESP-IDF Tools Offline 4.3.2 for example here), double-click the exe file to launch the ESP-IDF installation interface. The following demonstrates how to install ESP-IDF stable version v4.3.2 using the offline installer. You can submit logs to https://github.com/espressif/idf-installer/issues for help. The ESP-IDF GitHub repository is updated regularly, especially the master branch where new development takes place.

For production use, there are also stable releases available. The documentation for the current stable release version can always be found at this URL: https://docs.espressif.com/projects/esp-idf/en/stable/ Documentation for the latest version (master branch) can always be found at this URL: To start using ESP-IDF, select one of the following supported ESP SoC series. ESP-IDF is Espressif’s official IoT Development Framework for the ESP32, ESP32-S and ESP32-C series of SoCs.

It provides a self-sufficient SDK for any generic application development on these platforms, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys to big appliances and industrial devices. ESP-IDF (Espressif IoT Development Framework) is the official development framework created by Espressif Systems for its chips such as the ESP32, ESP32-S series, ESP32-C series, ESP32-H series, and ESP32-P series. It is an open-source software development toolkit based on C/C++, providing developers with comprehensive support from low-level hardware drivers to upper-level application development, and serves as the core tool for developing applications for ESP... The process of compiling and flashing a project’s code typically involves: Navigate to the project folder -> Set the chip model -> Configure the project (optional) -> Compile the project -> Flash the code. The following demonstrates how to compile and flash the "hello_world" example:

Locate the hello_world folder in the ESP-IDF installation directory and navigate to it using the cd command. Flash the code and start the serial monitor.
