ESP-IDF Components library

Build Status Build the documentation Docs Status

Components for Espressif ESP32 ESP-IDF framework and ESP8266 RTOS SDK.

Part of them ported from esp-open-rtos.

Supported versions of frameworks and devices

Chip Framework Versions
ESP32 ESP-IDF All officially supported versions (see Support Period Policy) and master
ESP32-S2 [1] ESP-IDF All officially supported versions and master
ESP32-C3 [1] ESP-IDF All officially supported versions and master
ESP8266 [2] ESP8266 RTOS SDK master, v3.4

[1] Use "idf.py set-target esp32s2" or "idf.py set-target esp32c3" before "idf.py menuconfig" to change the chip type.

[2] Due to the incompatibility of ESP8266 drivers and hardware, some libraries are not supported on ESP8266 (see "ESP8266" column in the tables).

How to use

ESP32

Clone this repository somewhere, e.g.:

cd ~/myprojects/esp
git clone https://github.com/UncleRus/esp-idf-lib.git

Add path to components in your project makefile, e.g:

PROJECT_NAME := my-esp-project
EXTRA_COMPONENT_DIRS := /home/user/myprojects/esp/esp-idf-lib/components
include $(IDF_PATH)/make/project.mk

or in CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
set(EXTRA_COMPONENT_DIRS /home/user/myprojects/esp/esp-idf-lib/components)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(my-esp-project)

or with CMake FetchContent

cmake_minimum_required(VERSION 3.11)
include(FetchContent)
FetchContent_Declare(
  espidflib
  GIT_REPOSITORY https://github.com/UncleRus/esp-idf-lib.git
)
FetchContent_MakeAvailable(espidflib)
set(EXTRA_COMPONENT_DIRS ${espidflib_SOURCE_DIR}/components)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(my-esp-project)

ESP8266 RTOS SDK

Clone this repository somewhere, e.g.:

cd ~/myprojects/esp
git clone https://github.com/UncleRus/esp-idf-lib.git

Add path to components in your project makefile, e.g:

PROJECT_NAME := my-esp-project
EXTRA_COMPONENT_DIRS := /home/user/myprojects/esp/esp-idf-lib/components
EXCLUDE_COMPONENTS := max7219 mcp23x17 led_strip max31865 ls7366r max31855
