Re: [gpsd-dev] PPS not showing in gpsmon/gpsd on RPi 3

My setup may be slightly different from Eric's.  It's a Pi 3.  I started with 
Raspbian Jessie Lite.

pps0 is created automagically by the boot stuff when you tell it that you 
want to use GPIO#<x> for PPS.

On my setup, gpsd actually makes /dev/pps1
(It isn't good for anything.)
