Switching between cores
~~~~~~~~~~~~~~~~~~~~~~~

If board supports multiple Arduino cores, you can switch between them using
``board_build.core`` option in :ref:`projectconf`.

For example, some boards of :ref:`platform_ststm32` development platform
support official ``stm32`` core and ``maple`` core by
`Roger Clark <https://github.com/rogerclarkmelbourne/Arduino_STM32>`_.

Example:

.. code-block:: ini

	[env:disco_f100rb_stm32]
	platform = ststm32
	framework = arduino
	board = disco_f100rb

	; Is set by default
	board_build.core = stm32

	[env:disco_f100rb_maple]
	platform = ststm32
	framework = arduino
	board = disco_f100rb

	; force to Maple core
	board_build.core = maple
