   GPIO D-Bus command-line client documentation

Command-line client
===================

With the manager running the user can run ``gpiocli`` to control GPIOs by
asking the ``gpio-manager`` to act on their behalf.

Examples
--------

Detect chips in the system:

.. code-block:: none

   $ gpiocli detect
   gpiochip0 [INT34C6:00] (463 lines)

Request a set of lines:

.. note::
   **gpiocli** exits immediately but the state of the lines is retained
   because it's the **gpio-manager** that requested them.

.. code-block:: none

   $ gpiocli request --output foo=active
   request0

Previous invocation printed out the name of the request by which the caller
can refer to it later. All active requests can also be inspected at any time:

.. code-block:: none

   $ gpiocli requests
   request0 (gpiochip1) Offsets: [5]


Print the information about the requested line using the information above:

.. code-block:: none

   $ gpiocli info --chip=gpiochip1 5
   gpiochip1   5:      "foo"           [used,consumer="gpiocli request",managed="request0",output,push-pull]

Change the value of the line:

.. code-block:: none

   $ gpiocli set foo=inactive

Read it back:

.. code-block:: none

   $ gpiocli get foo
   "foo"=inactive

We can even reconfigure it to input and enable edge-detection:

.. code-block:: none

   $ gpiocli reconfigure --input --both-edges request0

And wait for edge events:

.. code-block:: none

   $ gpiocli monitor cos
   21763952894920 rising  "foo"

And finally release the request:

.. code-block:: none

   $ gpiocli release request0

.. note::
   For more information please refer to the output of ``gpiocli --help`` as
   well as ``gpiocli <command> --help`` which prints detailed info on every
   available command.

.. note::
   Users can talk to **gpio-manager** using any **D-Bus** library available
   and are not limited to the provided client.
