Re: [itom-discussions] GPIB usage

[Marc G. <mar...@it...>]

Hi Erik,

as far as I know we don't have experience with any GPIB devices. However, I
try to give you a short overview about possibilities you have to connect
any device with itom:

On the one hand, it is possible to use dedicated Python packages to
directly control devices via Python. You can download such packages in the
latest version of itom (2.0.0)
using the integrated package manager. Examples for such packages are PyVISA
(for controlling VISA compatible devices) or packages for communicating via
RS232, TCP/IP or USB connections. It seems that your Agilent box is
compatible to VISA (see
http://www.keysight.com/main/editorial.jspx?cc=DE&lc=ger&ckey=1461160&nid=-33330.977662.00&id=1461160
).

On the other hand, itom has its plugin interface where you can write your
own plugins using C/C++. Then you can use any 3rd party library, like the
mentioned VXI-11 library. Hardware connected by plugins is directly
integrated into itom such that dedicated toolboxes, config dialogs or live
images for cameras are possible. Furthermore, the connected devices "live"
in  separate threads such that multithreading is always possible. Until
now, we provide many plugins for cameras, actuators or AD-converters. There
are also plugins for the communication via the RS232 or USB connection
(using libUSB). If you want to programm your own plugin, you are welcome to
do this. The necessary steps are described in the user documentation:
http://itom.bitbucket.org/latest/docs/07_plugins/development/plugin-development.html

Just some words about plugins:

- Written in C/C++
- Dependent on Qt (4.8 or >= 5.2)
- itom provides a SDK with libraries the plugin need to link agains. These
libraries provide access to itom or data structures like matrices.
- plugins are directly accessible via its uniform python interface
- Plugins can either follow the interface rules of a dataIO device, a
camera device, an actuator or an algorithm plugin
- You can for instance use an all-in-one-installation version (
http://sourceforge.net/projects/itom/files/all-in-one-build-setup/) that
provide a build-archive with all necessary 3rd party libraries that are
required to build itom and plugins on your own computer. These archives are
provided for Visual Studio 2010 or 2013.

I hope that I could give you a short overview about the possibilities.
Please feel free to ask any further questions.

Cheers
Marc
