Does anything other than gpsd write info to the SHM segment? >The (atomized) NMEA driver is the correct one to use with the GPS-18LVC. I've lost track of PPS support in Linux. The NMEA driver uses the PPS signal if the kernal supports grabbing the timestamp. I think gpsd does it without special kernel support. (I haven't tried it.) If so, it's probably better than the NEMA driver without kernel support. -- These are my opinions, not necessarily my employer's.
