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¶

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

on
