Note that latitudes and longitudes are in DMM format.
GETTING STARTEDKNOWN LIMITATIONSBUGSEXAMPLES
Get the position periodically:
#!/usr/bin/perl
use GPS::NMEA;
my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
Baud => 4800);
while(1) {
my($ns,$lat,$ew,$lon) = $gps->get_position;
print "($ns,$lat,$ew,$lon)\n";
}
Get the internal NMEA dump:
#!/usr/bin/perl
use GPS::NMEA;
use Data::Dumper;
my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
Baud => 4800);
while(1) {
$gps->parse;
# Dump internal NMEA data:
$gps->nmea_data_dump;
# Alternative to look at the internal NMEA data:
require Data::Dumper;
print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
}
