esp-idf-clion

configuration and setup clion with esp-idf

Install and setup esp idf

1. Create directory esp

mkdir -p ~/esp
cd ~/esp
git clone --recursive https://github.com/espressif/esp-idf.git

2. change directory to esp-idf

cd ~/esp/esp-idf

3. run script install.sh

./install.sh

Set up a sample project using CLion

1. Open clion IDE and make new project

2. Setup clion toolchain and cmake configuration Build, Execution, Deployment

   Setup clion toolchain

   Select Toolchains and change C Compiler and C++ Compiler with esp-idf compiler

   

   Example :

   C Compiler = /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc

   C++ Compiler = /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-g++

   Setup clion CMake

   1. Add IDF_PATH and PYTHON in CMake options **Example : **
   -DIDF_PATH = /Users/your_user/esp/esp-idf
   -DPYTHON = /Users/your_user/.espressif/python_env/idf4.4_py3.9_env/bin/python3.9

   2. Add IDF_PATH and PYTHON on Environment **Example : **
   IDF_PATH=/Users/ludinnento/esp/esp-idf
   PYTHON=/Users/ludinnento/.espressif/python_env/idf4.4_py3.9_env/bin/python3.9

   Setup Python Interpreter

   1. Select Python Interpreter 2. Add 3. Select System Interpreter 4. Search and choose python binary in .espressif/python_env/idf4.4_py3.9_env/bin/python3.9

3. Create directory main

   In this directory contain main.cpp or main.c of your esp program

   after create main.c/main.cpp, add another CMakeList.txt in this directory

   set(SOURCES "main.cpp")
   
   idf_component_register(SRCS ${SOURCES}
   INCLUDE_DIRS "")
       
   

4. Add CMakeList.txt inside application project

   cmake_minimum_required(VERSION 3.5)
   
   include($ENV{IDF_PATH}/tools/cmake/project.cmake)
   
   #set(CMAKE_FIND_ROOT_PATH /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf)
   set(CMAKE_C_COMPILER /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc)
   set(CMAKE_ASM_COMPILER /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-g++)
   set(CMAKE_C_COMPILER /Users/your_user/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc)
   
   project(esp32t)
   
   include_directories("src")
   

5. Set up esp-idf environment variables Open Clion Terminal, and running

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

6. Set up project In CLion terminal running :

   idf.py set-target esp32
   

   and

   idf.py menuconfig
   

   menuconfig used for configuration esp-idf

7. Build esp project In CLion terminal running :

   idf.py build
   

8. Flash

   idf.py -p ESP-PORT -b 115200 flash 
   

9. Monitor

   idf.py -p ESP-PORT -b 115200 monitor
