LCDout and large filesize 18F452 -> paging problem?

[mara]

Howdy,

LCD is in portD (data=D.0-D.3,RS=D.4,En=D.5)
TRISD = %01000000 (D.6 is input)
LCDout interferes pin D.7 as program size grows
PortD.7 = 1 won't make pin high...
pulsout portD.7,10000 still works... cannot figure it out.. o:-)

If I decrease code size, the problem disappears...
Has anyone faced same kinda problems?

thnx adv.

Post the code...

[mara]

Code is basicly like this:

DEFINE LCD_BITS 4
DEFINE LCD_DREG PORTD
DEFINE LCD_DBIT 0
DEFINE LCD_RSREG PORTD
DEFINE LCD_RSBIT 4
DEFINE LCD_EREG PORTD
DEFINE LCD_EBIT 5
TRISD = %01000000
LED VAR portD.7
...
--->8---(klipeti-klipeti)--->8--- (lots of stuff)
...
Lcdsub:
lcdout $FE,2,"hello"
lcdout $FE,C0,"world"
return
...
main:
LED=1 ' This should illuminate the led?
gosub Lcdsub
pause 500
LED=0
pause 500
goto Main

So, if I replace LED=1 with pulsout portD.7,65530 it will blink..
Otherwise it wont.. BUT..
If I remove gosubs away, LED=1 will work and it LED will blink..

It's this that makes it suspicious.


And which version of PBP are you using?

I just tried to save some bandwidth.. o:-)

Ok, how about this code, and ONLY this code:

DEFINE LCD_BITS    4
DEFINE LCD_DREG   PORTD
DEFINE LCD_DBIT    0	
DEFINE LCD_RSREG PORTD
DEFINE LCD_RSBIT  4	
DEFINE LCD_EREG   PORTD	
DEFINE LCD_EBIT    5		
TRISD = %10000000
LED VAR portD.7
Lcdsub:  lcdout $FE,2,"hello" : lcdout $FE,C0,"world" : return
main:  LED=1 : gosub Lcdsub : pause 500 : LED=0 : pause 500 : goto Main
END
