Quick Reference

Development Board

You can choose any of the ESP32/ESP32-S series development boards to use ESP-IoT-Solution, or choose one of the boards supported in boards component to quick start.

Powered by 40 nm technology, ESP32/ESP32-S 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 Build Environment

Setup ESP-IDF Environment

ESP-IoT-Solution is developed based on ESP-IDF functions and tools, so ESP-IDF development environment must be setup 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 Versions for details.

Get ESP-IoT-Solution

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

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

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

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

For other versions, replace release/v1.1 with the target branch name

Create Your Project

You can use the components of ESP-IoT-Solution in the following methods:

Method 1. Add all components' PATH of ESP-IoT-Solution to the project

Add the following code directly to the project's CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)

include($ENV{IOT_SOLUTION_PATH}/component.cmake)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)

project(empty-project)

Method 2. Add specified components' PATH of ESP-IoT-Solution to the project

Add the following code directly to the project's CMakeLists.txt, please add the REQUIRES components also:

set(EXTRA_COMPONENT_DIRS "${EXTRA_COMPONENT_DIRS} ${IOT_SOLUTION_PATH}/components/{component_you_choose}")

Method 3. Copy specified components of ESP-IoT-solution to the project's components directory

Please copy the REQUIRES components together.

Note: CMake based build system is recommended (default in IDF v4.0 and later). If using GNU Make, you can refer legacy build system based on GNU Make.

Set up the environment variables

Add ESP-IDF environment variables:

• For Windows CMD terminal, run the following command:

  %userprofile%\esp\esp-idf\export.bat
  

• For Linux or macOS terminal, run the following command:

  . $HOME/esp/esp-idf/export.sh
  

Add IOT_SOLUTION_PATH environment variables:

• For Windows CMD terminal, run the following command:

  set IOT_SOLUTION_PATH=C:\esp\esp-iot-solution
  

• For Linux or macOS terminal, run the following command:

  export IOT_SOLUTION_PATH=~/esp/esp-iot-solution
  

Note:

1. Please replace the example path with your actual installation path.
2. The environment variables set above only valid for the current terminal. please re-run the command if open new terminal.
