This directory is intended for project header files. | ||
|
||
A header file is a file containing C declarations and macro definitions | ||
to be shared between several project source files. You request the use of a | ||
header file in your project source file (C, C++, etc) located in `src` folder | ||
by including it, with the C preprocessing directive `#include'. | ||
|
||
```src/main.c | ||
|
||
#include "header.h" | ||
|
||
int main (void) | ||
{ | ||
... | ||
} | ||
``` | ||
|
||
Including a header file produces the same results as copying the header file | ||
into each source file that needs it. Such copying would be time-consuming | ||
and error-prone. With a header file, the related declarations appear | ||
in only one place. If they need to be changed, they can be changed in one | ||
place, and programs that include the header file will automatically use the | ||
new version when next recompiled. The header file eliminates the labor of | ||
finding and changing all the copies as well as the risk that a failure to | ||
find one copy will result in inconsistencies within a program. | ||
|
||
In C, the usual convention is to give header files names that end with `.h'. | ||
It is most portable to use only letters, digits, dashes, and underscores in | ||
header file names, and at most one dot. | ||
|
||

* Include Operation | ||
* Once-Only Headers | ||
* Computed Includes | ||

This directory is intended for project specific (private) libraries. | ||
PlatformIO will compile them to static libraries and link into executable file. | ||
|
||
The source code of each library should be placed in a an own separate directory | ||
("lib/your_library_name/[here are source files]"). | ||
|
||
For example, see a structure of the following two libraries `Foo` and `Bar`: | ||
|
||
|--lib | ||
| | | ||
| |--Bar | ||
| | |--docs | ||
| | |--examples | ||
| | |--src | ||
| | |- Bar.c | ||
| | |- Bar.h | ||
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html | ||
| | | ||
| |--Foo | ||
| | |- Foo.c | ||
| | |- Foo.h | ||
| | | ||
| |- README --> THIS FILE | ||
| | ||
|- platformio.ini | ||
|--src | ||
|- main.c | ||
|
||
and a contents of `src/main.c`: | ||
``` | ||
#include <Foo.h> | ||
#include <Bar.h> | ||
|
||
int main (void) | ||
{ | ||
... | ||
} | ||
|
||
``` | ||
|
||
PlatformIO Library Dependency Finder will find automatically dependent | ||
libraries scanning project source files. | ||
|
