Nokia lcd include , small footprint to suit pic16's

**richard** · - 27th May 2018, 03:57

I think I prefer my take on this
since:-
the font is automatically located
the pin/hw defines are in mcc ,therefore its simple to port to any chip that can read its own flash
its easy to debug
bigtext and inverted text are easily implemented
its only 100 or so words bigger

Code:

tried a pbp version for the 5 byte compressed packed font, the unpacking done without asm
takes more code space than the compressing saves

A great example. Thank you.

That's a shame but it was worth a try.

Thank you very much for the pointers and help. It's been a fun experiment and I've learned a lot.

Cheerful regards, Mike

ditto
and I finally figured out what I was doing wrong with asm psect labels

**richard** · - 27th May 2018, 04:49

whats next
a ttf
a double size font for digits (0 to 9 +- : )

Hi Richard,

Thanks for the fix on the single char problem, it works well but I've found another problem...

When I add DT Ints the big characters don't work, I tried with and without using mssp but same result.

Also there's something strange taking place with the led backlight insomuch as I need to sprinkle port pin enable code immediately following any lcd write (with or without DT Ints). I tried changing LCD_LIGHT from A.0 to A.1 (while leaving it connected to A.0) with no difference - does the Inc file employ any commands for the light?

Here's the edited code:

Code:

#CONFIG ; 16F1847.
        __config _CONFIG1, _FOSC_INTOSC & _WDTE_ON & _PWRTE_ON & _MCLRE_ON & _CP_OFF & _BOREN_OFF
        __config _CONFIG2, _PLLEN_OFF & _LVP_OFF
#ENDCONFIG

Is the Inc file compatible with DT Ints?

works perfectly if done correctly the include's order may matter, ioc int needs to configured
if your programmer is still connected to portb.7 that can load things up a bit [I leave mine connected and avoid using b6,b7 pins]
never use portx.x to set or clear pins , its just asking for rmw problems especially with fast fosc settings
always use latx.x when available or use a shadow register

Code:

#CONFIG ; 16F1847.
        __config _CONFIG1, _FOSC_INTOSC & _WDTE_ON & _PWRTE_ON & _MCLRE_ON & _CP_OFF & _BOREN_OFF

some pics of the big fnt

**wjsmarine** · - 10th June 2018, 09:58

Hi Richard,

I finally found some time to try your suggestions as shown in post #41 - it does not work for me.

Copying and pasting your code, I had no display until changing TRISA from %10010000 to all outputs and even then no big characters were seen until DTints and associated parts were commented out. Order of Includes made no difference.

There's still a problem with the backlighting as well because it initially is dim then changes to a short duration pulse of bright background coincident with each LCDCLR command. No difference whether displaying big characters or not wrt these bright flashes. When I add LCD_LIGHT = 1 in the mix I have no text displayed.

Any suggestions where I should go to from here?

Thanks and regards,
Bill

**richard** · - 27th May 2018, 12:21

include order does not seem to matter [as I hoped]
INCLUDE "DT_INTS-14.bas" ' Base Interrupt System
INCLUDE "ReEnterPBP.bas" ' Include if using PBP type interrupts
Include "nokia_ds.INC" ' bring it in
include "font7x5_16.bas"
works fine

a version with fonts of user defined size

this has a 14x10 font for two char 0,1 ie 2 rows 10 columns

fonts now have a header added to define rows/columns first chr and last chr

eg

Code:

#asm
psect FONT_table,class=CODE,local,delta=2
  GLOBAL _FNT
_FNT
        DW 0X0501, 0X207F  //1 ROW 5 COL CHR 32-127
        DW 0x0000, 0x0000, 0x0000, 0x005F, 0x0000 //  32 ' '  '!'
        DW 0x0007, 0x0007, 0x0014, 0x3F94, 0x3F94 //  34 '"'  '#'
        DW 0x122A, 0x3FAA, 0x0923, 0x0988, 0x3262 //  36 '$'  '%'
