//======================================================================
|
||
|
|
// Program: NMEAblink.ino
|
||
|
|
//
|
||
|
|
// Prerequisites:
|
||
|
|
// 1) NMEA.ino works with your device
|
||
|
|
//
|
||
|
|
// Description: This program will toggle the LED once per second,
|
||
|
|
// when the LAST_SENTENCE_IN_INTERVAL is received.
|
||
|
|
//
|
||
|
|
// Because no actual GPS data is used, you could disable all
|
||
|
|
// messages (except the LAST_SENTENCE) and all gps_fix members.
|
||
|
|
// It would still receive a 'fix' oncer per second, without
|
||
|
|
// without using any RAM or CPU time to parse or save
|
||
|
|
// the (unused) values. Essentially, this app uses the LAST_SENTENCE
|
||
|
|
// as a 1PPS signal.
|
||
|
|
//
|
||
|
|
// Note: Because this example does not use 'Serial', you
|
||
|
|
// could use 'Serial' for the gpsPort, like this:
|
||
|
|
//
|
||
|
|
// #define gpsPort Serial
|
||
|
|
//
|
||
|
|
// See GPSport.h for more information.
