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. 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. ESP-IDF is the official programming development framework for ESP-based microcontrollers. You can kind of think of it as the next step up from the Arduino IDE, giving you more options for customization, organization, and control.

It is also very similar in style to other industry frameworks such as STM32CubeIDE, utilizing Real-TimeOS (FreeRTOS) instead of the familiar Arduino super-loop. This is also great since it will teach you a lot about how many commercial technologies are programmed and provide you with the knowledge to switch around and use other microcontrollers later that aren’t... Being written in C, you also get access to lots of official libraries provided by the IC manufacturers themselves rather than 3rd party programmers. All these awesome perks said, ESP-IDF is also more complicated than Arduino and can be frustrating to get started with and understand. With more options for customizability comes more things to potentially mess up, making it not very beginner-friendly. If you’ve never programmed in Arduino (or similar) this post is probably not for you, but definitely come back once you feel more comfortable!

With this, let’s go through the ESP-IDF standard setup with Espressif-IDE. If you’d prefer to install ESP-IDF through an existing IDE such as Eclipse or VSCode, you will have to refer to the setup instructions from Espressif’s website. I will only be explaining the setup with the official Espressif-IDE (which I personally think is way easier and more stable). Let’s get started! First, you will want to navigate to the ESP-IDF installer which is linked here. After that, click on the option with ESP-IDF v5 and Espressif-IDE (or whatever the newest version is if you’re reading this at a later time).

The download should start. Note: At the time of writing this, the Online Installer has an issue where many of the ESP32 boards are not selectable as targets after installation. Not to worry though, since the offline installation is just as good and doesn’t have this problem. This tutorial will walk you through the process of setting up ESP-IDF using a Docker container and build a basic blinking LED example from this repository: https://github.com/ShawnHymel/course-iot-with-esp-idf/. The Espressif IoT Development Framework (ESP-IDF) is the official software development kit for the ESP32 family of microcontrollers. Built on a fork of FreeRTOS, it allows developers to create sophisticated, multi-threaded embedded applications that can handle the demands of real-world IoT systems.

ESP-IDF includes a comprehensive set of libraries for controlling GPIO pins, interfacing with sensors, and implementing full networking stacks for Wi-Fi, Bluetooth, and Ethernet. It is designed to provide the flexibility, performance, and reliability needed for professional IoT firmware development, making it the preferred choice for engineers building connected products at scale. While Arduino remains popular for hobbyist projects, there are many situations where ESP-IDF is the better choice. Developers who need production-ready code, precise control over system resources, and access to advanced configuration tools will find ESP-IDF indispensable. Its integration with FreeRTOS enables multi-tasking, while its modular architecture and rich peripheral support make it well-suited for applications that require scalability, security, and long-term maintainability. If your goal is to move beyond quick prototypes and into the realm of robust, deployable IoT devices, learning ESP-IDF is an essential step.

Sign up for the Learn Embedded Dev newsletter You technically do not need any hardware for this tutorial if you wish to emulate your program in qemu. However, if you wish to try it with real hardware, you will need an ESP32 development board, an LED, a 220 Ω resistor, a breadboard, and some jumper wires. Here is a list of the recommended parts: 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 for building and flashing firmware onto an ESP32 board.
