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-espressif32/examples/espidf-storage-sdcard
|
||||
|
||||
# Build project
|
||||
> platformio run
|
||||
|
||||
# Upload firmware
|
||||
> platformio run --target upload
|
||||
|
||||
# Build specific environment
|
||||
> platformio run -e esp32dev
|
||||
|
||||
# Upload firmware for the specific environment
|
||||
> platformio run -e esp32dev --target upload
|
||||
|
||||
# Clean build files
|
||||
> platformio run --target clean

|

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.

||||

||||
