.. currentmodule:: gpiozero
|
|
|
|
The GPIO Zero class hierarchy is quite extensive. It contains several base
|
|
classes (most of which are documented in their corresponding chapters):
|
|
|
|
* :class:`Device` is the root of the hierarchy, implementing base functionality
|
|
like :meth:`~Device.close` and context manager handlers.
|
|
|
|
* :class:`GPIODevice` represents individual devices that attach to a single
|
|
GPIO pin
|
|
|
|
* :class:`SPIDevice` represents devices that communicate over an SPI interface
|
|
(implemented as four GPIO pins)
|
|
|
|
* :class:`InternalDevice` represents devices that are entirely internal to
|
|
the Pi (usually operating system related services)
|
|
|
|
* :class:`CompositeDevice` represents devices composed of multiple other
|
|
devices like HATs
|
|
|
|
There are also several `mixin classes`_ for adding important functionality
|
|
at numerous points in the hierarchy, which is illustrated below:
