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. | |||||
Read more about using header files in official GCC documentation: | |||||
* Include Syntax | |||||
* 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 | |||||

| | |- 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) | |||||
{ | |||||
... | |||||

This directory is intended for PlatformIO Unit Testing and project tests. | |||||
Unit Testing is a software testing method by which individual units of | |||||
source code, sets of one or more MCU program modules together with associated | |||||
control data, usage procedures, and operating procedures, are tested to | |||||
determine whether they are fit for use. Unit testing finds problems early | |||||
in the development cycle. | |||||
