It uses the `MINMEA <https://github.com/kosma/minmea>`_ +library to parse standard NMEA messages and print out GPS data to the console. + +To use the program, provide the character device path for the GPS serial connection as the only argument. If no path is +provided, the program will default to ``/dev/ttyS1``. + +.. code:: console + + nsh> gps /dev/ttyS3 + Fixed-point Latitude...........: 0 + Fixed-point Longitude..........: 0 + Fixed-point Speed..............: 0 + Floating point degree latitude.: nan + Floating point degree longitude: nan + Floating point speed...........: nan Review Comment: As far as I can tell, this is what MINMEA parses a no-fix reading into. Once a fix is obtained the floating point numbers become real values. -- This is an automated message from the Apache Git Service.
