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. |
||||||
|
|
||||||
|

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 |
||||||
|

|- 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. |

This directory is intended for PIO 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. |
||||||
