ESP8266	ESP8266 RTOS SDK	`master`, v3.4

See "Supported on" column for each of the components.

How to use

ESP32-xx

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 CMakeLists.txt: e.g:

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
