Parsing GPS Data - Partially Working

Processing Electronics (Arduino, etc.)

Hello,

Pleased to see that you found a solution for your project.

I added a ‘\n’ to a string and tested your function and split().

trim() removes the ‘\n’.

Your function works the same as split() with this example:

Summary 
void setup() 
 {
  size(640, 360);
  String inString = "$GPGGA,182533.00,4355.94412,N,07859.68771,W,1,08,1.20,138.8,M,-35.9,M,,*6A\n";
  println(split(inString.trim(), ','));    //Gives a warning put still prints to console
  mySplit(inString.trim(), true);

  printArray(split(inString.trim(), ','));
  mySplit(inString.trim(), false);

  printArray(split(inString, ','));
  mySplit(inString, false);
  
  print("");	
  }

void draw() 
  {
  background(0);
  }


void mySplit (String str, boolean row) {
  int N = str.length(); 
  int i; 
  String str2 = "";  
  char c; 
  for (i = 0; i < N; i++){
    c = str.charAt(i);
    if (c == ',') {
      if (row)
        print(str2 + " ");
      else
        println(str2);
      str2 = "";
    }
    else {
     str2 += c;
    }
  }
 println(str2);
}

Source code for split()

I always like to see code examples to replace existing functions; all too often the workings of a function are hidden away from us and I like to write my own and\or see the source to help me better understand the underlying code and sometimes improve on it.

I did find some Android apps on Google Play to generate GPS data and send serial
data over Bluetooth and I wrote code to receive with Processing.
I was able to plot my movement in my room!

:)
