.. module:: psychopy.iohub.client

Starting the psychopy.iohub Process
=====================================

To use ioHub within your |PsychoPy| Coder experiment script, ioHub needs to
be started at the beginning of the experiment script. 

The easiest way to do this is by calling the launchHubServer function.

launchHubServer Function
--------------------------

.. autofunction:: launchHubServer

ioHubConnection Class
--------------------------

The psychopy.iohub.ioHubConnection object returned from the launchHubServer
function provides methods for controlling the iohub process and
accessing iohub devices and events.
