How to build PlatformIO based project
13+
=====================================
14+
15+
1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
16+
2. Download `development platform with examples <https://github.com/platformio/platform-espressif32/archive/develop.zip>`_
17+
3. Extract ZIP archive
18+
4. Run these commands:
19+
20+
.. code-block:: bash
21+
22+
# Change directory to example
23+
> cd platform-espressif32/examples/simba-blink
24+
25+
# Process example project
26+
> platformio run
27+
28+
# Upload firmware
29+
> platformio run --target upload

This directory is intended for the project specific (private) libraries.
3+
PlatformIO will compile them to static libraries and link to executable file.
4+
5+
The source code of each library should be placed in separate directory, like
6+
"lib/private_lib/[here are source files]".
7+
8+
For example, see how can be organised `Foo` and `Bar` libraries:
9+
10+
|--lib
11+
| |--Bar
12+
| | |--docs
13+
| | |--examples
14+
| | |--src
15+
| | |- Bar.c
16+
| | |- Bar.h
17+
| |--Foo
18+
| | |- Foo.c
19+
| | |- Foo.h
20+
| |- readme.txt --> THIS FILE
21+
|- platformio.ini
22+
|--src
23+
|- main.c
24+
25+
Then in `src/main.c` you should use:
26+
27+
#include <Foo.h>
28+
#include <Bar.h>
29+
30+
// rest H/C/CPP code
31+
32+
PlatformIO will find your libraries automatically, configure preprocessor's
33+
include paths and build them.
34+
35+
See additional options for PlatformIO Library Dependency Finder `lib_*`:
