    Default Display graphical font using Nokia3310LCD

    Hi everyone!
    I managed to run a demo application by Steve using the NokiaGLCD wrapper(http://www.picbasic.co.uk/forum/show...ght=3310+Nokia).
    Here is the sample code I'm uisng..
    Code:
            '--------------------------------< HelloWorld_16F877 >--------------------------------------

    My question is how can I display a font like the one below(please see attached image) this the hex equivalent...
    $08, $E0, $00, $E2, $01, $EE, $02, $62, $02, $06, $02, $0E, $03, $FC, $01, $F0, $01, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00 ; for letter m
    Hope anyone can give me a hint on this.

    Thanks in advance,

    Open the Include and check out ADDCUSTOMCHAR macro. That should be easy enough for a single character. If you want to build a whole new font set, then check the TABLE_SYMBOLS etc etc sections.

    Refer to HelloWorld_2_16F877.pbp

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Also check out the Readme.txt file located in ...NokiaGlcd\Document folder. There's a short example how to use ADDCUSTOMCHAR macro.

    Thanks Steve for the response, I'm still figuring it out how it works(by trial and error ) and learn it in the process..I will post here my result.

    I'm still stuck with this simple code I modified from Steve's NokiaGlcd examples..
    Code:
    	DEFINE GLCD_CHAR_IN_EEPROM			   ' store/read character/lookuptable to/from EEPROM
    		DEFINE GLCD_STRING_IN_EEPROM		   ' store/read string to/from EEPROM
    		DEFINE GLCD_USE_SPECIFIC_CHARACTER	   ' We will define our own set of character to be used
            INCLUDE "..\Include\GLCD_NOKIA.PBP"    ' Plug the Nokia Driver/Wrapper in here
    		ASM
    		CHARTABLESTART
    				ADDCUSTOMCHAR CHR_CUSTOM_0, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
    				ADDCHAR 'e'
    				ADDCHAR 'l'
    				ADDCHAR 'o'
    				ADDCHAR 'w'
    				ADDCHAR 'r'
    				ADDCHAR 'd'
    				ADDCHAR '!' 
    		CHARTABLEEND
    		ENDASM        
            
            '
            '------------------------------< Main program >---------------------------------------------
            '
            ASM
            GLCD_CLS     ; Clear the screen (if not initialized yet, it will do automatically)
            GLCDOUT_AT?STR 0,0,"Hello World!"   ; Show String on Line 0
            GLCDOUT_AT?STR 0,1,"Wello World!"   ; Show String on Line 1
            GLCDOUT_AT?STR 0,2,"j"   ; Show String on Line 2
          
            ENDASM
    
    
    Here:
    
    
    GOTO Here   ' sit & spin
    as I understood characters not defined within CHARTABLESTART and CHARTABLEEND will not be displayed...but I'm still having trouble displaying this character (j) 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
    any idea what I'm missing?

    read again the readme.txt file example ...

    you have 2 extra argument in ADDCUSTOMCHAR, here you should have
    ADDCUSTOMCHAR CHR_CUSTOM_0, 0x04, 0x00, 0x00, 0x00, 0x00
    not
    ADDCUSTOMCHAR CHR_CUSTOM_0, 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00

    it compiled with no problem now, but custom character won't display on the lcd, probably I'm still doing it wrong..
    I'm expecting a letter 'j' in the 3rd row.
    Code:
    	DEFINE GLCD_CHAR_IN_EEPROM			   ' store/read character/lookuptable to/from EEPROM
    		DEFINE GLCD_STRING_IN_EEPROM		   ' store/read string to/from EEPROM
    		DEFINE GLCD_USE_SPECIFIC_CHARACTER	   ' We will define our own set of character to be used
            INCLUDE "..\Include\GLCD_NOKIA.PBP"    ' Plug the Nokia Driver/Wrapper in here
    		ASM
    		CHARTABLESTART
    				ADDCUSTOMCHAR CHR_CUSTOM_0, 0x04, 0x00, 0x00, 0x00, 0x00
    				ADDCHAR 'e'
    				ADDCHAR 'l'
    				ADDCHAR 'o'
    				ADDCHAR 'w'
    				ADDCHAR 'r'
    				ADDCHAR 'd'
    				ADDCHAR '!' 
    		CHARTABLEEND
    		ENDASM        
            
            '
            '------------------------------< Main program >---------------------------------------------
            '
            ASM
            GLCD_CLS     ; Clear the screen (if not initialized yet, it will do automatically)
            GLCDOUT_AT?STR 0,0,"Hello World!"   ; Show String on Line 0
            GLCDOUT_AT?STR 0,1,"Wello World!"   ; Show String on Line 1
            GLCDOUT_AT?STR 0,2,"j"   ; Show 'j' on Line 2
          
            ENDASM
    
    
    Here:
    
    
    GOTO Here   ' sit & spin
    I appreciate the time for helping out.

    You'll see a J once you'll add it in the character you want to use.... no coincidence why you don't have the H nor the W either

    Again it's all explained in the Readme.txt file...

    Hi Tacbanon,

    Did you manage to create bigger fonts with Steve's program?

    I see your last post shows the display with obvious different font but still within the 6x8 field. How does one make a larger font exceeding this area?

    I'd appreciate your help and maybe a snippet of code if you've been successful. My aim is to make really big fonts (0-9, +, -, decimal point mid-height, C, F and degree symbol) in a 12x16 or 4 normal character size locations (7 chars per line, 3 lines) on the Nokia LCD using Steve's excellent wrapper. If it can't be done I can do other mapping but then lose Mister_e's utility.

    Steve if you're around perhaps you'd like to add some comments also? All help appreciated.

    Regards to all,
    Bill
