// Title : NMEA protocol function library |
// Author : Pascal Stang - Copyright (C) 2002 |
// Created : 2002.08.27 |
// Revised : 2002.08.27 |
// Version : 0.1 |
// Target MCU : Atmel AVR Series |
// Editor Tabs : 4 |
// |
// NOTE: This code is currently below version 1.0, and therefore is considered |
// to be lacking in some functionality or documentation, or may not be fully |
// tested. Nonetheless, you can expect most functions to work. |

/// \par Overview |
/// This library parses and decodes the standard NMEA data stream from a |
/// GPS and stores the position, velocity, and time solutions in the gps.c |
/// library. |
