Macro Definition Documentation

NMEA_EXTENSIONS

#define NMEA_EXTENSIONS

if defined will include more NMEA sentences

Comment out the definition of NMEA_EXTENSIONS to make the library use as little memory as possible for GPS functionality only. The ARDUINO_ARCH_AVR test should leave it out of any compilations for the UNO and similar.library

Enumeration Type Documentation

nmea_check_t

enum nmea_check_t

type for resulting code from running check()
