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:
CODEC's HAL
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
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
ESP-WHO
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
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
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_modem enables connectivity with GSM/LTE modems using AT commands or PPP protocol, see the esp_modem documentation.
mdns (mDNS) is a multicast UDP service that is used to provide local network service and host discovery, see the mdns documentation.
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.
asio is a cross-platform C++ library, see https://think-async.com/Asio/. It provides a consistent asynchronous model using a modern C++ approach. , see the asio documentation.
ESP-BSP
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
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 README.md for more information.
