Expected Contrustor Error

Projects Programming
1

I took this example (Arduino Playground - SparkFunSerLCD) and placed it inside my code (which really doesn't have anything in it except global variables), but it gives me the "error: expected constructor, destructor, or type conversion before '-' token" error on compile. I tried a few things with no luck, and if this is posted on the Playground I would think it should work, but maybe I've done something obvious that I missed.

I didn't include the setup{} because the only thing is the serial.begin, and some routines that don't yet function and don't reflect on the LCD issue.

void loop()
{
  BtnDbnc = millis(); //reset button debounce timer
  
  if ((millis() - BtnDbnc) > 100){ //digital debounce
    // button debounce
  }
  
  selectLineOne();
  Serial.print(analogRead(0)); // read scale and display
  delay(50);
  
}

// ~~ LCD Display Commands ~~ \\
void selectLineOne(){  //puts the cursor at line 0 char 0.
   Serial.print(0xFE, BYTE);   //command flag
   Serial.print(128, BYTE);    //position
   delay(10);
}
void selectLineTwo(){  //puts the cursor at line 0 char 0.
   Serial.print(0xFE, BYTE);   //command flag
   Serial.print(192, BYTE);    //position
   delay(10);
}
void goTo(int position) { //position = line 1: 0-15, line 2: 16-31, 31+ defaults back to 0
if (position<16){ Serial.print(0xFE, BYTE);   //command flag
              Serial.print((position+128), BYTE);    //position
}else if (position<32){Serial.print(0xFE, BYTE);   //command flag
              Serial.print((position+48+128), BYTE);    //position 
} else { goTo(0); }
   delay(10);
}

void clearLCD(){
   Serial.print(0xFE, BYTE);   //command flag
   Serial.print(0x01, BYTE);   //clear command.
   delay(10);
}

void backlightOn(){  //turns on the backlight
    Serial.print(0x7C, BYTE);   //command flag for backlight stuff
    Serial.print(157, BYTE);    //light level.
   delay(10);
}
void backlightOff(){  //turns off the backlight
    Serial.print(0x7C, BYTE);   //command flag for backlight stuff
    Serial.print(128, BYTE);     //light level for off.
   delay(10);
}
void serCommand(){   //a general function to call the command flag for issuing all other commands   
  Serial.print(0xFE, BYTE);
}

but it gives me the "error: expected constructor, destructor, or type conversion before '-' token" error on compile.

Please paste the EXACT error message you are getting. What line highlights in the source code?

Here is the line it is mad at, but that is the exact error code.

   Serial.print(0xFE, BYTE);   //command flag
4 
// ~~ LCD Display Commands ~~ \\

Looks pretty doesn't it?
Do you know what "" does?
No?
Then don't use it.

To be honest, I find that weird... it fixed the problem but it's behind the comment slashes so it shouldn't matter. I know for a fact on C# it doesn't matter.

Thanks for poining out my obvious. :smiley:

Backslash is a continuation character, so the function definition becomes part the comment.
Without the declaration, the body of the function gives a syntax error.

I know for a fact on C# it doesn't matter.

And here, C# doesn't matter ]:smiley:
