Custom interface in micro ros

[Hariveerabadran]

how to create the custom interface in espidf_component. i tried to add header file in cmakelist but its not working.

cmakelist.txt

cmake_minimum_required(VERSION 3.5)

set(EXTRA_COMPONENT_DIRS "$ENV{HOME}/esp/micro_ros_espidf_component-humble")
include_directories("$ENV{HOME}/ros2_ws/install/custom_interface/include")
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(cmd_vel)

i tried to add in main/cmakelist.txt. But that will not work as well

hi @Hariveerabadran you can use

Directory structure recommended is

project/
├── main/
│ ├── CMakeLists.txt
│ └── main.c
├── components/
│ └── custom_interface/
│ ├── include/
│ │ └── custom_interface.h
│ ├── src/
│ │ └── custom_interface.c
│ └── CMakeLists.txt
└── CMakeLists.txt

and in components/custom_interface/CMakeLists.txt change for add file *.c

idf_component_register(
SRCS "src/custom_interface.c"
INCLUDE_DIRS "include"
)
