Espressif’s Frameworks

Here you will find a collection of the official Espressif libraries and frameworks.

Espressif Audio Development Framework

The ESP-ADF is a comprehensive framework for audio applications including:


  • Music Players and Recorders

  • Audio Processing

  • Bluetooth Speakers

  • Internet Radios

  • Hands-free devices

  • Speech Recognition

This framework is available at GitHub: ESP-ADF.


ESP-CSI is an experimental implementation that uses the Wi-Fi Channel State Information to detect the presence of a human body.

See ESP-CSI project for more information about it.

Espressif DSP Library

The library provides algorithms optimized specifically for digital signal processing applications. This library supports:

  • Matrix multiplication

  • Dot product

  • FFT (Fast Fourier Transform)

  • IIR (Infinite Impulse Response)

  • FIR (Finite Impulse Response)

  • Vector math operations

This library is available here: ESP-DSP library.

ESP-WIFI-MESH Development Framework

This framework is based on the ESP-WIFI-MESH protocol with the following features:

  • Fast network configuration

  • Stable upgrade

  • Efficient debugging

  • LAN control

  • Various application demos



The ESP-WHO is a face detection and recognition framework using the ESP32 and camera. To know more about the project, see ESP-WHO on GitHub.

ESP RainMaker

ESP RainMaker is a complete solution for accelerated AIoT development. Using ESP RainMaker, you can create AIoT devices from the firmware to the integration with voice-assistant, phone apps and cloud backend.

ESP-IoT-Solution contains commonly used device drivers and code frameworks when developing IoT systems. The device drivers and code frameworks within the ESP-IoT-Solution are organized as separate components, allowing them to be easily integrated into an ESP-IDF project.

ESP-IoT-Solution includes:

  • Device drivers for sensors, display, audio, GUI, input, actuators, etc.

  • Framework and documentation for low power, security, storage, etc.

  • Guide for Espressif open source solutions from practical application point.

ESP-Protocols repository contains collection of protocol components for ESP-IDF. The code within the ESP-Protocols is organized into separate components, allowing them to be easily integrated into an ESP-IDF project. In addition to that, each component is available in IDF Component Registry.

ESP-Protocols components:


ESP-BSP repository contains Board Support Packages (BSPs) for various Espressif’s and 3rd party development boards. BSPs are useful for quick start on a supported board. Usually they contain pinout definition and helper functions, that will initialize peripherals for the specific board. Additionally, the BSP would contain drivers for external chips populated on the development board, such as sensors, displays, audio codecs etc.


ESP-IDF-CXX contains C++ wrappers for part of ESP-IDF. The focus is on ease of use, safety, automatic resource management and shifting checks to compile time instead of failing at run time. There are C++ classes for ESP-Timer, I2C, SPI, GPIO and other peripherals or features of ESP-IDF. ESP-IDF-CXX is available as a component from the component registry. Please check the project’s for more information.
