bryan.ee_laptop/ec/lib/README.md

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
|  |  |--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.
