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 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
|

|
| | |- Bar.h

||||||
|

|

|
||||||

and a contents of `src/main.c`:
|
||||||
|
```
|
||||||
|
#include <Foo.h>
|
||||||
|
#include <Bar.h>
|
||||||
|
|

int main (void)
|

|
{

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.
