This directory is intended for the project specific (private) libraries.
|
||||
PlatformIO will compile them to static libraries and link to executable file.
|
||||
|
||||
The source code of each library should be placed in separate directory, like
|
||||
"lib/private_lib/[here are source files]".
|
||||
|
||||
For example, see how can be organized `Foo` and `Bar` libraries:
|
||||
|
||||
|--lib
|
||||
| |
|
||||
| |--Bar
|
||||
| | |--docs
|
||||
| | |--examples
|
||||
| | |--src
|
||||
| | |- Bar.c
|
||||
| | |- Bar.h
|
||||
| | |- library.json (optional, custom build options, etc) http://docs.platformio.org/page/librarymanager/config.html
|
||||
| |
|
||||
| |--Foo
|
||||
| | |- Foo.c
|
||||
| | |- Foo.h
|
||||
| |
|
||||
| |- readme.txt --> THIS FILE
|
||||
|
|
||||
|- platformio.ini
|
||||
|--src
|
||||
|- main.c
|
||||
|
||||
Then in `src/main.c` you should use:
|
||||
|
||||
#include <Foo.h>
|
||||
#include <Bar.h>
|
||||
|
||||
// rest H/C/CPP code
|
||||
|
||||
PlatformIO will find your libraries automatically, configure preprocessor's
|
||||
include paths and build them.
