Functions

func Enumerate

func Enumerate() (ret []string, err error)

Enumerate collects all gps device paths. TODO: udev enumeration.

Types

type GPS

type GPS struct {
	// contains filtered or unexported fields
}

func NewGPS(p string) (*GPS, error)

NewGPS opens a GPS stream from a given device path.

func (*GPS) Close

func (g *GPS) Close() error

Close terminates the GPS stream and returns any error encountered.

func (*GPS) NMEA

func (g *GPS) NMEA() <-chan NMEA

NMEA streams GPS messages. Closes on error.

type Knots
