Hi guys,

I have 12 error: expected primary-expression before '.' token. in my code. Please can you help me fix these.

This is the error code appearing:

#define GPS 
Adafruit_GPS GPS;

Oops

What's wrong with that?

What's wrong with that?

Here's what the compiler sees, after the preprocessor has done its stuffAdafruit_GPS;

5

What do I need to change it to and should it fix the other errors?

I don't know what you think the "#define GPS" is doing, so I'd simply delete it, and so how it goes.
I didn't read any further than that, so I don't know if anything is lurking further into your code.

7

That then comes up with GPS is not defined in this scope errors

I can't see your code, I can't see your error messages.

I have attached the code these are the errors that are appearing.

#define GPSSerial

Same problem as earlier

What happened to the

Adafruit_GPS GPS;

?

What's all this junk?

oled.println("GPSSP V. 2.0.0");
  oled.print("Initializing");
  oled.println(); 
  oled.println(); 
  oled.print("RTI Development");
  delay(500);
  oled.clear();
  oled.println("GPSSP V. 2.0.0");
  oled.print("Initializing.");
  oled.println(); 
  oled.println(); 
  oled.print("RTI Development");
  delay(500);
  oled.clear();
  oled.println("GPSSP V. 2.0.0");
  oled.print("Initializing..");
  oled.println(); 
  oled.println(); 
  oled.print("RTI Development");
  delay(500);
  oled.clear();
  oled.println("GPSSP V. 2.0.0");
  oled.print("Initializing...");
  oled.println(); 
  oled.println();

Please use the IDE's auto-format tool before posting your code.

I must have accidentally deleted it, let me add that bit back in. The 'junk' is for when the screen is booting up and getting ready to print the important information.

How can I fix the issue of what the compiler sees.

The junk is the same code, repeated seven times.
Why?

You can either fix it, or you can enlist the help of someone else.
