16 \fBgpiv_trig\fP triggers a CCD camera and a (double Nd_YAGG) laser for
17 Particle Image velocimetry (PIV). The code uses a kernel module
18 gpivtrig_rtl from the gpivtrig package that depends on the Real Time
19 Application Interface (RTAI) and RealtimeLinux. Trigger pulses are
20 send to the parallel port of the PC (/dev/lpt0 or /dev/lpt1; see the
21 configure script of the gpivtrig package) at bins #1 (camera),
22 #2 and #3 (first and second laser respectively). The program may be
23 started directly if all modules have been loaded or by the
24 gpiv_control script, also included in the gpivtrig package, which
25 takes care of the loading and unloading of the needed kernel
26 modules. Currently, \fBgpiv_trig\fP is tested with RTAI-3.1 and the
