Overview
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.
