Finally you will need to define ``MODULE_EXAMPLE_ENABLED`` to 1. This
can be done by adding ``CFLAGS_EXTRA=-DMODULE_EXAMPLE_ENABLED=1`` to
the ``make`` command, or editing ``mpconfigport.h`` or
``mpconfigboard.h`` to add
.. code-block:: c
#define MODULE_EXAMPLE_ENABLED (1)
Note that the exact method depends on the port as they have different
