Gentlemen,

a new version of EZGPIB is available.

One of the biggest improvements of EZGPIB is that I have found a flawless
way for communication between EZGPIB and ProfiLab. ProfiLab is a German (may
be installed in English and French language too) based construction kit
system for data acquisition systems that is in many aspects comparable to
LABVIEW. However it has a much smaller footprint than LABVIEW, is a bit
limited in it’s capabilities against LABVIEW but costs less then 100 €!!

One of the few flaws of ProfiLab is that it does not provide GPIB
communications. That makes it the ideal partner for EZGPIB which makes GPIB
communication a snap. EZGPIB on the other hand lacks the rich set of graphic
controls and displays that ProfiLab provides. They team up! Among other ways
ProfiLab can communicate with hardware or other software by means of an
“imported DLL”. These imported DLLS appear on the working screen as a
building block having a number of inputs and a number of outputs. I have
written such a DLL for ProfiLab which can be configured to have 1 to 1000
inputs and 1 to 1000 outputs. Once the DLL is configured it can be connected
to other ProfLab components in the usual way.  Nothing more needs to be
obeyed in the ProfiLab project. The counter piece to that in EZGPIB is a set
of two functions named

EZGPIB_ProflabOut(Output:Integer; Value:Double)

and

EZGPIB_ProflabIn(Input:Integer): Double

which directly operate on the ProfiLab building block by means of shared
memory. The ProfiLab directory contains the necessary DLL that should be
copied to ProfiLab’s root directory together with it’s INI-file. The
Profilab directory also includes a ProfiLab demo project that matches the
EZGPIB’s ProfiLab.488 demo.


A short demo AVI of EZGPIB in conjunction with ProfiLab can be found here:

The software can be downlaoded from the ususal place.

Enjoy.
