Help need using BigFont Library

dariods8474 · January 2, 2025, 10:41am

I am trying to use the BigFont library available @ BigFont_Library. i want to use 3x3 BigFonts(3 rows x 3 Columns). i am unable to initialize the library and print a big font digit. just trying to initialize in setup gives me error. Please help


#include <LiquidCrystal.h>
#include <BigFont.h>

LiquidCrystal lcd(7, 8, 9, 10, 11, 12);  // Define LCD display pins RS, E, D4, D5, D6, D7
void setup() {
 //Serial.begin(115200);
 lcd.begin(20, 4);
 lcd.clear();
 BigFont BigFont(3);

}

void loop() {
 }

Example of use is:

    BigFont bigfont(3); // declaration, 2 for 3colx2rows, 3 for 3colx3rows or 4 4colx4rows digits
    
    bigfont.setFontSize(size); // can be used to change display font size 2,3 or 4 at runtime
    
    // somewhere in the code...

    	if(_bigFontSize == 2){
		bigfont.printbigchar(lcd, 0, 0, 0);
		bigfont.printbigchar(lcd, this->_dt.hour, 3, 0);
	} else if(_bigFontSize == 3){
		bigfont.printbigchar(lcd, 0, 0, 0);
		bigfont.printbigchar(lcd, this->_dt.hour, 3, 0);
	} else {
		bigfont.printbigchar(lcd, 0, 0, 0);
		bigfont.printbigchar(lcd, this->_dt.hour, 4, 0);
	}

The BigFont.h file seems to lack an include statement for Arduino.h, not sure how it ever compiled correctly since without that include the byte data type is not defined. Likely it depended on LiquidCrystal.h including Arduino.h, but the version I have does not.

dariods8474 · January 2, 2025, 1:31pm

Even after putting #include <Arduino.h> produces the same error 'byte' has not been declared

david_2018 · January 2, 2025, 1:37pm

Did you put the include statement in the BigFont.h file? Putting it in the sketch will not help.

dariods8474 · January 2, 2025, 1:42pm

The errors have gone. Sorry I unmarked your answer as solution. New problem arises

dariods8474 · January 2, 2025, 2:16pm


#include <LiquidCrystal.h>
#include <BigFont.h>

LiquidCrystal lcd(7, 8, 9, 10, 11, 12);  // Define LCD display pins RS, E, D4, D5, D6, D7
void setup() {
  //Serial.begin(115200);
  lcd.begin(20, 4);
  lcd.clear();
  BigFont BigFont(3);
  BigFont.loadchars(lcd);
  BigFont.printbigchar(lcd, 1, 3, 0); // This prints
}

void loop() {
  for(byte i = 0; i < 10;i++){
    BigFont.printbigchar(lcd, i, 3, 0); //This gives error
// expected unqualified-id before '.' token
//     BigFont.printbigchar(lcd, i, 8, 0);
//            ^
    delay(1000);
  }
}

please guide

Where did you get the BigFont library from ?

dariods8474 · January 2, 2025, 2:56pm

All details mentioned in my original post

dariods8474 · January 2, 2025, 3:03pm

I found the problem

BigFont BigFont(3);

Should not declare this in setup
