Espressif IoT Development Framework

Configuration:

framework = espidf

Espressif IoT Development Framework. Official development framework for ESP32 chip

Tutorials

• Get started with ESP-IDF and ESP32-DevKitC: debugging, unit testing, project analysis

• Book: Developing IoT Projects with ESP32: Automate your home or business with inexpensive Wi-Fi devices (using the PlatformIO with ESP-IDF)

Note

Each release of the Espressif 32 platform uses a specific version of ESP-IDF. The latest version of the platform only supports the latest stable version of the framework.

Configuration

The general project configuration (default optimization level, bootloader configuration partition tables, etc) is set in a single file called sdkconfig in the root folder of the project. This configuration file can be modified via a special target called menuconfig (PlatformIO v4.3.0 greater is required):

pio run -t menuconfig

Warning

ESP-IDF requires some extra tools to be installed in your system in order to build firmware for supported chips. Most of these tools are available in PlatformIO ecosystem as standalone packages, but in order to use configuration tool called menuconfig several additional packages need to be installed on Linux-based systems:

libncurses5-dev flex bison

More details about required packages can be found in the official ESP-IDF documentation - Standard Setup of Toolchain for Linux.

Hint

If menuconfig is not showed properly in the integrated VS Code terminal try changing the default terminal shell by clicking the dropdown menu on the top-right of the terminal panel and selectiing the Select Default Shell option.

Hint

In case the UP and DOWN arrows don’t work in menuconfig try using the J key to move the cursor down and K to move the cursor up. Another option is to use - and + keys on the numeric keypad.

Project Structure

The ESP-IDF framework requires an unusual project structure because most of the framework configuration is performed by the native for the ESP-IDF build system called CMake.

A typical PlatformIO project for the ESP-IDF framework must have the following structure:

project_dir
├── include
├── src
│    ├── CMakeLists.txt
│    └── main.c
├── CMakeLists.txt
└── platformio.ini

Tip

It’s also possible to use the default ESP-IDF project structure with main folder. To specify main as the folder with source files use src_dir option, for example:

[platformio]
src_dir = main

[env:esp32dev]
platform = platformio/espressif32
framework = espidf
board = esp32dev

Besides the files related to PlatformIO project, there are several additional ESP-IDF-specific files: the main CMakeLists.txt, project-specific CMakeLists.txt in src_dir and optional default configuration file sdkconfig.defaults. CMakeLists.txt files enable features supported by the ESP-IDF’s build system, e.g. ULP configuration, adding extra components, etc. A typical CMakeLists.txt file in the root folder has the following content:

# The following lines of boilerplate have to be in your project's CMakeLists
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.16.0)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(project-name)

The second CMakeLists.txt in src_dir is responsible for controlling the build process of the component and its integration into the overall project. The minimal component CMakeLists.txt file simply registers the component to the build system using idf_component_register:

idf_component_register(SRCS "foo.c" "bar.c")

The files specified using idf_component_register are used ONLY for generating build configurations, but it’s highly recommended to specify all application source files in order to keep the project compatible with the usual ESP-IDF workflow.

Warning

By default PlatformIO expects source files to be located in the src folder. At the same time, the default location for source files within the ESP-IDF build system is a special folder with the name main. Renaming the main component may require users to manually specify additional dependencies:

idf_component_register(SRCS "main.c" REQUIRES idf::mbedtls)

More details in the official ESP-IDF documentation - Renaming main component.

Due to the current limitations of CMake file-based API, there is no way of generating build configuration for source files written in various programming languages if they are not specified in idf_component_register command. If your project contains libraries written in languages that differ from the language used for the main application you need to create an empty file with the desired extension (e.g. *.cpp for C++) in order to force CMake generate build configuration for this language.

Note

Build configuration generated for source files specified in idf_component_register is also used as the base build environment for project sources (including libraries).

ESP-IDF components

ESP-IDF modules as modular pieces of standalone code might be useful for structuring reusable code or including third party components that aren’t part of ESP-IDF.

These components contain either a single CMakeLists.txt file which controls the build process of the component and its integration into the overall project. An optional Kconfig file defines the component configuration options that can be set via menuconfig. Some components may also include Kconfig.projbuild and project_include.cmake files, which are special files for overriding parts of the project. All valid components will be compiled as static libraries and linked to the final firmware. There are two possible ways of adding extra components to PlatformIO project:

• By adding a new component to an optional folder called components in the root of your project. This folder will be automatically scanned for valid components.

• Using EXTRA_COMPONENT_DIRS option in the root CMakeLists.txt file. This option represents a list of extra directories to search for components.

An example of specifying esp-aws-iot as an extra component:

# The following lines of boilerplate have to be in your project's CMakeLists
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.16)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
list(APPEND EXTRA_COMPONENT_DIRS esp-aws-iot)
project(subscribe_publish)

Warning

Since src_dir is also passed to CMake as an extra component, you should only append to EXTRA_COMPONENT_DIRS variable in order not to override the default package.

Since the build may not work correctly if the full path to sources is greater than 250 characters (see CMAKE_OBJECT_PATH_MAX) it might be a good idea to keep modules close to the project files.

ULP coprocessor programming

If you want to take measurements using ADC, internal temperature sensor or external I2C sensors, while the main processors are in deep sleep mode you need to use ULP coprocessor. At the moment ULP can be used only with the Espressif IoT Development Framework.

All ULP code, usually written in assembly in files with .S extension, must be placed into a separate directory with the name ulp in the root folder of your project. So your project structure should look like this:

project_dir
├── include
├── src
│    ├── CMakeLists.txt
│    └── main.c
├── ulp
│    └── ulp_code.S
├── CMakeLists.txt
└── platformio.ini

Since PlatformIO uses the code model generated by CMake it’s mandatory to specify ULP source files in CMakeLists.txt as well. An example of typical CMakeLists.txt for ULP:

idf_component_register(SRCS "ulp_adc_example_main.c")
#
# ULP support additions to component CMakeLists.txt.
#
# 1. The ULP app name must be "ulp_main"
set(ulp_app_name ulp_main)
#
# 2. Specify all assembly source files.
#    Paths are relative because ULP files are placed into a special directory "ulp"
#    in the root of the project
set(ulp_s_sources "../ulp/adc.S")
#
# 3. List all the component source files which include automatically
#    generated ULP export file, ${ulp_app_name}.h:
set(ulp_exp_dep_srcs "ulp_adc_example_main.c")
#
# 4. Call function to build ULP binary and embed in project using the argument
#    values above.
ulp_embed_binary(${ulp_app_name} ${ulp_s_sources} ${ulp_exp_dep_srcs})

See full examples with ULP coprocessor programming:

• https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-ulp-adc

• https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-ulp-pulse

More details are located in the official ESP-IDF documentation - ULP coprocessor programming.

Limitations

At the moment several limitations are present:

• No whitespace characters allowed in project paths. This limitation is imposed by the native ESP-IDF build system. This affects users that have a whitespace in their username or added a whitespace to the project name. As a workaround, it’s recommended to move core_dir to a folder without spaces. For example:

  [platformio]
  core_dir = C:/.platformio
  
  [env:esp32dev]
  platform = platformio/espressif32
  framework = espidf
  board = esp32dev
  

• The src_filter option cannot be used. It’s done to preserve compatibility with existing ESP-IDF projects. List of source files is specified in the project CMakeLists.txt file.
