Hinweise:
1.) es lassen sich nicht nur geograf. Daten, sondern auch Datum, Uhrzeit, Geschwindigkeit, Kurs und Satellitendaten abfragen
2.) Üblicherweise arbeiten die Sketche für Uno und Nano mit SoftwareSerial():
Code: Alles auswählen
SoftwareSerial ss(4, 3);
void loop()
{
while (ss.available() > 0)
gps.encode(ss.read);
//...
Stattdessen lässt sich aber auch Hardware-Serial verwenden, am besten per UART1 oder UART2 auf Mega oder Due:
Code: Alles auswählen
setup(){
Serial.begin(115200); // UART0 für USB-Serial-Terminal Window
Serial1.begin(9600): // UART1 für das GPS-Modul
}
void loop()
{
while (Serial1.available() > 0)
gps.encode(Serial1.read);
//...
}3.) Liste für die verfügbaren Daten:
Code: Alles auswählen
Serial.println(gps.location.lat(), 11); // Latitude in degrees (double)
Serial.println(gps.location.lng(), 11); // Longitude in degrees (double)
Serial.print(gps.location.rawLat().negative ? "-" : "+");
Serial.println(gps.location.rawLat().deg); // Raw latitude in whole degrees
Serial.println(gps.location.rawLat().billionths);// ... and billionths (u16/u32)
Serial.print(gps.location.rawLng().negative ? "-" : "+");
Serial.println(gps.location.rawLng().deg); // Raw longitude in whole degrees
Serial.println(gps.location.rawLng().billionths);// ... and billionths (u16/u32)
Serial.println(gps.date.value()); // Raw date in DDMMYY format (u32)
Serial.println(gps.date.year()); // Year (2000+) (u16)
Serial.println(gps.date.month()); // Month (1-12) (u8)
Serial.println(gps.date.day()); // Day (1-31) (u8)
Serial.println(gps.time.value()); // Raw time in HHMMSSCC format (u32)
Serial.println(gps.time.hour()); // Hour (0-23) (u8)
Serial.println(gps.time.minute()); // Minute (0-59) (u8)
Serial.println(gps.time.second()); // Second (0-59) (u8)
Serial.println(gps.time.centisecond()); // 100ths of a second (0-99) (u8)
Serial.println(gps.speed.value()); // Raw speed in 100ths of a knot (i32)
Serial.println(gps.speed.knots()); // Speed in knots (double)
Serial.println(gps.speed.mph()); // Speed in miles per hour (double)
Serial.println(gps.speed.mps()); // Speed in meters per second (double)
Serial.println(gps.speed.kmph()); // Speed in kilometers per hour (double)
Serial.println(gps.course.value()); // Raw course in 100ths of a degree (i32)
Serial.println(gps.course.deg()); // Course in degrees (double)
Serial.println(gps.altitude.value()); // Raw altitude in centimeters (i32)
Serial.println(gps.altitude.meters()); // Altitude in meters (double)
Serial.println(gps.altitude.miles()); // Altitude in miles (double)
Serial.println(gps.altitude.kilometers()); // Altitude in kilometers (double)
Serial.println(gps.altitude.feet()); // Altitude in feet (double)
Serial.println(gps.satellites.value()); // Number of satellites in use (u32)
Serial.println(gps.hdop.value()); // Horizontal Dim. of Precision (100ths-i32)

This sample sketch demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object.
It requires the use of SoftwareSerial, and assumes that you have a
9600-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
Alternatively: Serial1 (RX1+TX1, pin 18+19 on Mega/Due)
