Espressif IoT Solution Overview

• 中文版

ESP-IoT-Solution contains device drivers and code frameworks for the development of IoT systems, providing extra components that enhance the capabilities of ESP-IDF and greatly simplify the development process.

ESP-IoT-Solution contains the following contents:

• Device drivers for sensors, display, audio, input, actuators, etc.
• Framework and documentation for Low power, security, storage, etc.
• Guide for espressif open source solutions from practical application point.

Quick Reference

Development Board

You can choose any of the ESP series development boards to use ESP-IoT-Solution or choose one of the boards supported in boards component for a quick start.

Powered by 40nm technology, ESP series SoC provides a robust, highly integrated platform, which helps meet the continuous demands for efficient power usage, compact design, security, high performance, and reliability.

Setup Environment

Setup ESP-IDF Environment

ESP-IoT-Solution is developed based on ESP-IDF functions and tools, so ESP-IDF development environment must be set up first, you can refer Setting up Development Environment for the detailed steps.

Please note that different versions of ESP-IoT-Solution may depend on different versions of ESP-IDF, please refer to the below table to select the correct version:

ESP-IoT-Solution	Dependent ESP-IDF	Major Change	User Guide	Support State
master	>= v4.4	support component manager and new chips	Docs online	active, new feature develop
release/v1.1	v4.0.1	IDF version update, remove no longer supported code	v1.1 Overview	archived
release/v1.0	v3.2.2	legacy version	v1.0 Overview	archived

Since the master branch uses the ESP Component Manager to manager components, each of them is a separate package, and each package may support a different version of the ESP-IDF, which will be declared in the component's idf_component.yml file

Get Components from ESP Component Registry

If you just want to use the components in ESP-IoT-Solution, we recommend you use it from the ESP Component Registry.

The registered components in ESP-IoT-Solution are listed below:

Component Name	Version
aht20
at581x
avi_player
ble_conn_mgr
ble_ota
bootloader_support_plus
button
cmake_utilities
esp_lcd_gc9b71
esp_lcd_axs15231b
esp_lcd_panel_io_additions
esp_lcd_nv3022b
esp_lcd_sh8601
esp_lcd_spd2010
esp_lcd_st7701
esp_lcd_st77903_rgb
esp_lcd_st77916
esp_lcd_st77922
esp_lcd_touch_spd2010
esp_lcd_touch_st7123
keyboard_button
esp_simplefoc
esp_sensorless_bldc_control
esp_tinyuf2
extended_vfs
gprof
iot_usbh
iot_usbh_cdc
iot_usbh_modem
ir_learn
knob
led_indicator
lightbulb_driver
esp_msc_ota
openai
pwm_audio
usb_device_uvc
usb_stream
xz
zero_detection

You can directly add the components from the Component Registry to your project by using the idf.py add-dependency command under your project's root directory. eg run idf.py add-dependency "espressif/usb_stream" to add the usb_stream, the component will be downloaded automatically during the CMake step.

Please refer to IDF Component Manager for details.

Get ESP-IoT-Solution Repository

If you want to Contribute to the components in ESP-IoT-Solution or want to start from the examples in ESP-IoT-Solution, you can get the ESP-IoT-Solution repository by following the steps:

• If select the master version, open the terminal, and run the following command:

  git clone --recursive https://github.com/espressif/esp-iot-solution
  

• If select the release/v1.1 version, open the terminal, and run the following command:

  git clone -b release/v1.1 --recursive https://github.com/espressif/esp-iot-solution
  

Build and Flash Examples

We highly recommend you Build Your First Project to get familiar with ESP-IDF and make sure the environment is set up correctly.

There is no difference between building and flashing the examples in ESP-IoT-Solution and in ESP-IDF. In most cases, you can build and flash the examples in ESP-IoT-Solution by following the steps:

1. Change the current directory to the example directory, eg cd examples/usb/host/usb_audio_player.
2. Run idf.py set-target TARGET to set the target chip. eg idf.py set-target esp32s3 to set the target chip to ESP32-S3.
3. Run idf.py build to build the example.
4. Run idf.py -p PORT flash monitor to flash the example, and view the serial output. eg idf.py -p /dev/ttyUSB0 flash monitor to flash the example and view the serial output on /dev/ttyUSB0.

Some examples may need extra steps to setup the ESP-IoT-Solution environment, you can run export IOT_SOLUTION_PATH=~/esp/esp-iot-solution in Linux/MacOS or set IOT_SOLUTION_PATH=C:\esp\esp-iot-solution in Windows to setup the environment.
