It is easy to do as Linux now has a PPS generator built-in. There is nothing to do but configure it. Expect the PPs to have a random 2 uSec or more jitter. It could be much worse. I think the PPS generation uses timer interrupts. The timer advances in uSec ticks and then there is some latency so expect and error in the range of a 'handful of uSec." -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
