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
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:
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
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 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.
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_websocket_client is a managed component for esp-idf that contains implementation of [WebSocket protocol client](https://datatracker.ietf.org/doc/html/rfc6455) for ESP32, see the esp_websocket_client documentation.
