=============
 Description
=============

The code is organized in 2 layers; a low-level communication layer,
and a highter level which allows to describe precisely a GPIB device,
communicate asynchronously with it, etc.

Low level
=========

The low level communication process is managed by the module
``pygpibtoolkit.prologix``, in which there is a class names ``GPIB``
that knows how to initialize the GPIB device, send commands and
receive data from the bus, perform GPIB polls, etc.

Example::

  from pygpibtoolkit.prologix import GPIB
  cnx = GPIB() # by default, it is the controller in charge
  idn = cnx.send_command("*IDN?", 12) # sends the idn command to device at GPIBaddress 12
  print idn

  cnx.set_address(12) # we will talk to this device 12 for a while
  datablock = cnx.send_command('DDBN')

  if cnx.check_srq():
      print "A Service Request has been sent"
