NMEA 0183

Modeled after the nmea_2000_router and the can_router, let you plugin nmea_0183_uart and nmea_0183_log as backends that generate NMEA 0183 messages as input.

Then use nmea_0813_router:attach() for applications to subscribe to nmea_message's.

Checkout nmea_0183_srv.erl how to setup subscription and handle simple nmea_0183 inputs.

To automatically add backends to the nmea_0183_router an interface list is used in sys.config example:

{nmea_0183,
  [{interfaces,
     [{nmea_0183_log,0,[{file,"priv/oland_log.gps"}]},
      {nmea_0183_uart,1,[{device,"/dev/ttyUSB0"},{baud, 4800}]}
     ]}]}

The backends can also be started manually with a start function in the backend, and the backends can also be used standalone ( set options [{router, undefined}, {receiver, self()}] . )
