[SOLVED] Creating custom component need help

Posted: Wed Aug 11, 2021 8:52 am

Hello. I am trying to create custom component for my esp-idf project. I have started off with hello_world example and in my project folder I have created components folder. In my components folder I have place my .c and .h files as well as CMakeLists.txt.
See the image for my project structure:
https://ibb.co/z5h9XFn



I am now just trying to get test component to work. Forget about https_ota


So as you can see from the image, in my components/test folder I have 3 files:
1. test.c
2. test.h
3. CMakeLists.txt

In my test.c:

Code: Select all

#include "test.h"

void test_printf(){
    printf("hello world from test file");
}

In my test.h:

Code: Select all

void test_printf();
In my CMakeLists.txt:

Code: Select all

idf_component_register(SRCS "test.c"
                    INCLUDE_DIRS "")

All I am trying to do now, is to include "test.h" in my main.c and use this test_printf function in my main.c

Trying to include "test.h" in my main.c gives an error:

Code: Select all

Hi,

Have you tried to create the new component by the following command?

Code: Select all

idf.py create-component <components/comp_name>
You can try by this way to create new components for your project.

I dont have any clue how do i use idf.py commands. I do everything from visual studio code.
I have tried to run this command on terminal and got error:
'idf.py' is not recognized as an internal or external command,

But I assume it does exactly the same as I have did. It jus creates component directory if its not created and then places my component in there which is exactly what I have done.


According to the documentation, there should be nothing else needed to do

You need to add the "." for the includes.

Code: Select all

idf_component_register(SRCS "test.c"
                    INCLUDE_DIRS ".")
