Parsing GPS Data - Partially Working

Processing Electronics (Arduino, etc.)
5

That info helped a little bit. Perhaps I’m still missing the obvious? Is it possible to link a YouTube video to explain in detail?

In any case, this is what happens after more experimenting. I cannot get the entire NMEA block
to read into Processing via serialEvent(). It works when moving the code within draw(). Here
are the outputs:

THIS code:


 void serialEvent(final Serial s){ 
    inStringGPS = splitTokens(s.readStringUntil(ENTER));
 }

and THIS code:


void serialEvent(final Serial s){ 
   while(gpsPort.available() > 0){
      inStringGPS = splitTokens(s.readString());   //Until(ENTER));
  }
}

Output the following:

[0] "$GPGLL,4355.94453,N,07859.68160,W,171628.00,A,A*72"
[0] "$GPGLL,4355.94453,N,07859.68160,W,171628.00,A,A*72"
[0] "$GPGLL,4355.94453,N,07859.68160,W,171628.00,A,A*72"
[0] "$GPGLL,4355.94453,N,07859.68160,W,171628.00,A,A*72"
[0] "$GPGSV,4,4,16,29,04,028,,31,25,092,29,46,19,240,,51,32,218,*7C"
[0] "$GPGLL,4355.94448,N,07859.68158,W,171629.00,A,A*72"

However, this code gives me:

 import processing.serial.*;
 Serial gpsPort;
 
 float  speedometer;
 int gpsHeading;
 String[] gpsData = new String[500]; //65
 String[] inStringGPS;
 
 void draw() {
 
   background(0);
  
   while(gpsPort.available() > 0){
    inStringGPS = splitTokens(gpsPort.readString());
   }
  
  gpsData = split(inStringGPS[0], ','); 
  
   String blockRMC = gpsData[0];
   String str3 = "$GPRMC";
  
   if (str3.equals(blockRMC) == true){  // $GPRMC  
     gpsHeading = int(gpsData[9]);
     speedometer = float(gpsData[7]); 
     text(gpsHeading, 40, 40);
     text(speedometer, 80, 40);
   }     
    printArray(gpsData);
 }

[8] "$GPGLL,4355.94291,N,07859.68291,W,172645.00,A,A*7F"

Why is serialEvent missing most of the NMEA data block?
