Display graphical font using Nokia3310LCD

[tacbanon]

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..

        '--------------------------------< HelloWorld_16F877 >--------------------------------------

        '       Basic code example to display the usual Hello World on the NOKIA GLCD.

        ENDASM


Here:   GOTO Here   ' sit & spin   
        '

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

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..

	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
