How to build PlatformIO based project
|
||||||
|
=====================================
|
||||||
|
|
||||||
|
1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
|
||||||
|
2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
|
||||||

3. Extract ZIP archive

4. Run these commands:

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
|
||||||
|
| |--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.

The source code of each library should be placed in separate directory, like

|
||||||
|
|

For example, see how can be organized `Foo` and `Bar` libraries:
|

|

|
|--lib

#include <Foo.h>

#include <Bar.h>

How to build PlatformIO based project
|
||||||
|
=====================================
|
||||||
|
|
||||||
|
1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
|
||||||
|
2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
|
||||||
|
3. Extract ZIP archive
|
||||||
|
4. Run these commands:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
# Change directory to example
|
||||||
|
> cd platform-espressif8266/examples/espidf-http-request
|
||||||
|
|
||||||
|
# Process example project
|
||||||
|
> platformio run
|
||||||
|
|
||||||
|
# Upload firmware
|
||||||
|
> platformio run --target upload

|
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 organised `Foo` and `Bar` libraries:
|
||||||
|
|
||||||
|
|--lib
|
||||||
|
| |--Bar
|
||||||
|
| | |--docs
|
||||||
|
| | |--examples
|
||||||
|
| | |--src
|
||||||
|
| | |- Bar.c
|
||||||
|
| | |- Bar.h
|
||||||
|
| |--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.
|
||||||
