Hi folks, so I have an arduino uno that has a CC3000 Wifi Shield and a CN-06 Ublox Neo 6M GPS hooked up to it. I've managed to run some code to get the Wifi Sheild to behave properly by itself and I've also written some code that gets the GPS to function and spit out lat's long's etc.
My dilemma is when I try and combine the two codes and then Arduino gets all pissy with me. Here's the code:
Please excuse my messy commenting etc.
//Libraries

#include <stdlib.h>
#include <SoftwareSerial.h>
//Set Harware Configuration Pins etc.

data_pos ++;
}
buffer[field_pos] = '\0';
}
When I try and compile this I get an error message saying "too few arguments to function 'void getField(char*, int)' on line 16?
There's no code on line 16 
Can anyone shed some light on my predicament?
