Hi, Not sure if it is interesting for you guys but I wrote a simple program for e.g. Linux (or any other system with the pps api implemented) that listens on a pps source waiting for a pulse and then toggles a gpio pin. That way you can measure the latency introduced by the the kernel when listening from userspace. Note that there's a little extra latency due to the gpio-pin handling.
You can also use it e.g. blink a led :-) It is on github: https://github.com/flok99/pps2gpio Folkert van Heusden -- MultiTail cok yonlu kullanimli bir program, loglari okumak, verilen kommandolari yerine getirebilen.
