NAME

       gpiv_trig - triggers a (double Nd_YAGG) laser with a CCD camera.

SYNOPSIS

       gpiv_trig [-h | --help] [-i | --interactive] [-v | --version] [-V | --verbose]

DESCRIPTION

       gpiv_trig  triggers  a  CCD camera and a (double Nd_YAGG) laser for Particle Image velocimetry (PIV). The
       code uses a kernel module  gpivtrig_rtl  from  the  gpivtrig  package  that  depends  on  the  Real  Time
       Application  Interface  (RTAI)  and RealtimeLinux. Trigger pulses are send to the parallel port of the PC
       (/dev/lpt0 or /dev/lpt1; see the configure script of the gpivtrig package) at bins #1 (camera), #2 and #3
       (first and second laser respectively). The program may be started  directly  if  all  modules  have  been
       loaded  or  by  the  gpiv_control script, also included in the gpivtrig package,  which takes care of the
       loading and unloading of the needed kernel modules. Currently, gpiv_trig is tested with RTAI-3.1 and  the
       linux kernel-2.4.27.

       This program uses the TRIG parameters. The command line options are explained below.

Options

       -h | --help
              On-line help.

       -i | --interactive
              Prompt for confirmation.

       -v | --version
              Print version information on standard output, then exit successfully.

       -V | --verbose
              program behaves more verbose during operation showing what is going on
