Camera Link PCI Express (PCIe) Gen1 Framegrabbers

Image Capture and Display

EDT, Inc.

2012 March 16

For demonstration or debugging purposes, you can run this application when no board is installed in the
system; the image window then shows a test pattern. To do so, at the command line, enter...

initcam -u dmy0 -f

configuration_file



pdvshow -dmy0

If you have not yet initialized the driver, select your camera or simulator from the list and click

If the image window shows incorrect data (usually because the camera model has been changed since the
last driver initialization), select

Camera > Setup

to select the correct camera model.

To access camera controls, use the

PdvShow

toolbar and menus. For details, see

PdvShow

Help

Compiling PdvShow

To experiment with example code in this application, use the source code indicated below.

•

For Windows, look in

pdvshow

in the appropriate Visual Studio project subfolder. For details, see the

README

file in the

pdvshow

subfolder of the main distribution folder (by default,

C:\EDT\Pdv

NOTE

The

pdvshow

executable comes already built on Windows distributions, so you need not compile it

unless you wish to experiment with the source code.

•

For Linux, see the source code and the

README

file in the

pdv_flshow

subdirectory of the main dis-

tribution directory (by default,

/opt/EDTpdv

•

For Mac OS, there is no

PdvShow

, but you can experiment by exploring the information in this guide.

For more about the cross-platform FLTK-based version of

PdvShow

, see

README

in the

pdv_flshow

subdirectory of the main distribution directory (by default,

/opt/EDTpdv

If the open-source FTLK library (required by

pdv_flshow

) is not installed,

make pdvshow

will try to install

it. If the installation fails, you will need to install FLTK 1.1.9 by hand.

To install FLTK 1.1.9:

pdv_flshow

, open

fltk-1.1.9-source.tar.gz

and run...

gunzip fltk-1.1.9-source.tar.gz



tar –xf fltk-1.1.9-source.tar

...to install

fltk-1.1.9

, run...

make



make install

pdv_flshow

, run...

make pdvshow
