API - Device Source Tools
|
|
=========================
|
|
|
|
.. module:: gpiozero.tools
|
|
|
|
GPIO Zero includes several utility routines which are intended to be used with
|
|
the :doc:`source_values` attributes common to most devices in the library.
|
|
These utility routines are in the ``tools`` module of GPIO Zero and are
|
|
typically imported as follows::
|
|
|
|
from gpiozero.tools import scaled, negated, all_values
|
|
|
|
Given that :attr:`~gpiozero.SourceMixin.source` and
|
|
:attr:`~gpiozero.ValuesMixin.values` deal with infinite iterators, another
|
|
excellent source of utilities is the :mod:`itertools` module in the standard
|
|
library.
|
|
|
|
.. warning::
|
|
|
|
While the devices API is now considered stable and won't change in
|
|
backwards incompatible ways, the tools API is *not* yet considered stable.
|
|
It is potentially subject to change in future versions. We welcome any
|
|
comments from testers!
