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

ESP-IDF

  • master
  • 4.x
  • 3.2.2

ESP32 Chip Support

  • ESP32
  • ESP32S2

Use "idf.py set-target esp32s2" before "idf.py menuconfig" to change the chip type.

ESP8266 RTOS SDK

  • master
  • 3.3
  • 3.2

Due to incompatibilities in ESP8266 RTOS SDK's SPI driver and hardware, the following libraries are not supported on ESP8266.

  • max7219
  • mcp23x17
  • led_strip

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
include $(IDF_PATH)/make/project.mk
