pygpibtoolkit
=============

pygpibtoolkit_ is a Python_ toolkit for talking with GPIB devices. It
consist in a set of python modules (low-level and some more
high-level) in order to ease writing python code to play with GPIB
devices.

There are also some utility commands and GUI tools written using this
library (and PyQt5 for GUI tools).

The aim of the project is to have an infrastructure that make it easy
to write code to command/interact with GPIB-controlled devices, and,
as a corrolary, make it easy to write "description" code for specific
test equipments.

Quick start
===========

The simplest way to install pygpibtoolkit_ is to use pip_. I strongly recommend
you use virtualenvs_ for this, for example via virtualenvwrapper_ or pew_. Here
is an example session using virtualenvwrapper_ on a Debian stretch machine:

.. code-block:: bash

   david@host:~$ mkvirtualenv -p /usr/bin/python3 pygpib
   Already using interpreter /usr/bin/python3
   Using base prefix '/usr'
   New python executable in /home/david/.virtualenvs/pygpib/bin/python3
   Also creating executable in /home/david/.virtualenvs/pygpib/bin/python
   Installing setuptools, pkg_resources, pip, wheel...done.

   (pygpib) david@host:~$ pip install pygpibtoolkit
   [...]

   Successfully installed PyQt5-5.10.1 numpy-1.14.3 pygpibtoolkit-0.1.0 pyqtgraph-0.10.0 pyserial-3.4 sip-4.19.8
   (pygpib) david@pavo:~$ pygpib-detect --help
   usage: A simple tool for detecting connected GPIB devices [-h] [-d DEVICE] [-v]

   optional arguments:
     -h, --help            show this help message and exit
	 -d DEVICE, --device DEVICE
                           Device of connected Prologix GPIB bundle
                           [/dev/ttyUSB0]
	 -v, --verbose

   >>> ctl = GPIBController(cnx)
   >>> dvm = c.register_device(24, "HP3456A")
   >>> dvm.S0F1 # set DVM to DC Voltage mode
