Hello,
Im new to arduino programming. Im doing project related to GPS. Im using a simple code from TInyGPS library and TInyGPSPlus library. Both are failure. I did not get my output.
I'm using GPS module, SKYLAB SKM53. Here is the link.
Here is the code i used.
- TinyGPS13 - simple test
#include <SoftwareSerial.h>
#include <TinyGPS.h>
/* This sample code demonstrates the normal use of a TinyGPS object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/TinyGPS gps;
SoftwareSerial ss(4, 3);void setup()
{
Serial.begin(115200);
ss.begin(9600);Serial.print("Simple TinyGPS library v. "); Serial.println(TinyGPS::library_version());
Serial.println("by Mikal Hart");
Serial.println();
}void loop()
{
bool newData = false;
unsigned long chars;
unsigned short sentences, failed;// For one second we parse GPS data and report some key values
for (unsigned long start = millis(); millis() - start < 1000;)
{
while (ss.available())
{
char c = ss.read();
// Serial.write(c); // uncomment this line if you want to see the GPS data flowing
if (gps.encode(c)) // Did a new valid sentence come in?
newData = true;
}
}if (newData)
{
float flat, flon;
unsigned long age;
gps.f_get_position(&flat, &flon, &age);
Serial.print("LAT=");
Serial.print(flat == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flat, 6);
Serial.print(" LON=");
Serial.print(flon == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flon, 6);
Serial.print(" SAT=");
Serial.print(gps.satellites() == TinyGPS::GPS_INVALID_SATELLITES ? 0 : gps.satellites());
Serial.print(" PREC=");
Serial.print(gps.hdop() == TinyGPS::GPS_INVALID_HDOP ? 0 : gps.hdop());
}gps.stats(&chars, &sentences, &failed);
Serial.print(" CHARS=");
Serial.print(chars);
Serial.print(" SENTENCES=");
Serial.print(sentences);
Serial.print(" CSUM ERR=");
Serial.println(failed);
if (chars == 0)
Serial.println("** No characters received from GPS: check wiring **");
}

DeviceExample.ino
A simple demonstration of TinyGPS++ with an attached GPS module
Testing TinyGPS++ library v. 0.92
by Mikal HartNo GPS detected: check wiring.
As the pin connection for software serial.
pin 4(rx) connects to pin GPS TX
pin 3(tx) connects to pin GPS RX
Im not sure where i left out.
