Select Arduino version to use

[Bouni]

Is there a way to let platformio use another version of the Arduino framework than the one you install with it?
I've done some extensions to the HardwareSerial part and want to use them in one of my projects.

I can implement a way to say PlatformIO about .platformio tool/+chains directory. It uses ${USER_HOME}/.platformio now.

For example, you can setup

# Unix
export PIOHOME_DIR=%HERE_IS_NEW_DIR%
# or Windows
set PIOHOME_DIR=%HERE_IS_NEW_DIR%

Then

$ platformio install atmelavr

In these cases you will have different locations with tool chains and Arduino frameworks. You will use PIOHOME_DIR environment to say PlatformIO which tools+framework it should use.

What do you think about it?

I would really like to write the path to what arduino directory to use in my platformio.ini.
By default take the .platformio one, if specified otherwise in the platformio.ini, take that one.

Thanks a lot for your efforts!

Details are described in documentation.

To install latest development version use these commands:

$ pip uninstall platformio
$ pip install https://github.com/ivankravets/platformio/archive/develop.zip

Then you can control your PlatformIO home directory per project (install special platforms/frameworks/... for project).

Thanks a lot for request and sorry for delay! :)
