Adafruit_GPS GPS(&Wire);

int    opc = 0;
String op = "";         // Init str
String gpsString = "";  // Init str

void setup() {
  GPS.begin(0x10);
  Serial.begin(115200);
  Serial.println("GPS data disp on SSD1306");
}

void loop() {
  String gpsString = String(GPS.read());
  if (gpsString = "$") {
    disp ();
  }
}

void disp()
{
  op = "";
  op = gpsString;
  for (int opc = 0; opc < 5; opc ++) {
    String gpsString = String(GPS.read());
    op = op + gpsString;
  }
  Serial.print(op);
}

Any pointers to the detail on the data retrieved by GPS.read? construct chars used to signal beginning and end of lines of data? does the function have any other parameters?

All will be revealed if you study the read function in the Adafruit_GPS.cpp library file.

Thnx !

You probably meant:

  if (gpsString == "$") {
    disp ();
  }

Ahh thnx !
