coundown problem on LCD

[Dave]

SuB-ZeRo, You are using almost all of the available ram with the 3 arrays you are trying to declare. The processor you are using only has 192 bytes available and you are declaring 180 of them. Why?

SuB-ZeRo,
I beleive you want to do something like this:
DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 0
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 3
DEFINE LCD_BITS 4
DEFINE LCD_LINES 2
DEFINE LCD_COMMANDUS 2000
DEFINE LCD_DATAUS 50
saniye var byte
dakika var byte
saat var byte
saniye=59
dakika=59
saat=59
loop:
LCDOut $FE,1 'ekranı temizle
lcdout "KALAN SURE"
LCDOut $Fe,$C0
LCDOUT #saat,":",#dakika,":",#saniye
saniye = saniye - 1
if saniye > 59 then
saniye = 59
dakika = dakika - 1
if dakika > 59 then
dakika = 59
saat = saat - 1
if saat > 59 then
saat = 59
endif
endif
endif
pause 1000
goto loop
end

Are you sure you are using the following line correctly?

second VAR BYTE [59] 'I WANT TO LIMIT THE TIME

This doesn't limit the byte to 59 it creates an array of 59 bytes. It sounds like you want 1 byte that doesn't go any higher than 59. I would do the following within a loop:

IF UP=0 Then ' Button Up command
While UP=0:Wend
second = v+1
IF second > 59 Then second = 1
LCDOut $FE,1
EndIF

i thing every body understand me wrong coz i want to set i timer that start with 00:00:00 and if i push the button that connected to the RA4 it will plus the reverse timer 30 minute 00:00:00 will become 00:30:00 after than countdown beguns 00:29:59 .......00:28:59...... till 00:00:00 but when the countdown starts or continues if i push the button again for example when the time 00:25:19 it will plus 30 minute again and the time will become 00:55:19 every push will plus 30 minute 01:25:19 ... 01:55:19 and goes.My problem is when i try to start the time from 00:00:00 on the LCD i see 0:0:0 if i push the button it becomes 0:30:0 after than it goes 0:29:1=>0:29:0=>0:28:1=>0:28:0 i really cant find the problem

try:
LCDOUT DEC2 saat,":",DEC2 dakika,":",DEC2 saniye

DEC2 will always print two digits to your display.

ok i resolve the problem the real problem is putting the codes to the right place i am getting to learn programming in pic basic
