//  Program: NMEAsimple.ino
//
//  Description:  This program shows simple usage of NeoGPS
//
//  Prerequisites:
//     1) NMEA.ino works with your device (correct TX/RX pins and baud rate)
//     2) At least one of the RMC, GGA or GLL sentences have been enabled in NMEAGPS_cfg.h.
//     3) Your device at least one of those sentences (use NMEAorder.ino to confirm).
//     4) LAST_SENTENCE_IN_INTERVAL has been set to one of those sentences in NMEAGPS_cfg.h (use NMEAorder.ino).
//     5) LOCATION and ALTITUDE have been enabled in GPSfix_cfg.h
//
//  'Serial' is for debug output to the Serial Monitor window.
