thanks for the help....:-)
by the way, i got something don't understand
why my display on second keep fresh and fresh in LCD and it made it look like blinking?
is the any problem with my LCD display or need to add extra component?
i using standard connection according to picbasic manual book.
my LCD model:BONA MC1602-17

I would guess a PAUSE of 100 some place after the LCD updates will stop the blink.

here is my programe
'4Mhz Crystal is use

DEFINE LCD_LINES 2

hour VAR BYTE
dhour VAR BYTE
minute VAR BYTE
second VAR BYTE
scaler VAR BYTE
i VAR BYTE


Pause 100 'wait lcd startup

hour = 0
minute = 0
second = 0
scaler = 0



OPTION_REG = %11010101
INTCON = %10100000

display:

LCDOut $fe,1

dhour = hour
IF (hour//12) = 0 Then
dhour = dhour + 12
EndIF
IF hour < 12 Then
LCDOut DEC2 dhour,":",DEC2 minute,":",DEC2 second, "AM"
LCDOut $fe,$c0,"Simple Test"
Else
LCDOut DEC2 (dhour - 12),":",DEC2 minute,":",DEC2 second, "PM"
LCDOut $fe,$c0,"Simple Test"
EndIF



GoSub timing

GoTo display

timing:
scaler = scaler + 1

IF scaler > 61Then
scaler = 0
second = second + 1

IF second > 59Then
second = 0
minute = minute +1

IF minute > 59Then
minute = 0
hour = hour + 1

IF hour > 24 Then
hour = 0

EndIF
EndIF
EndIF
EndIF

Return
End

where should i put the pause 100 and how i can display simple test in second line?
it seem it run only time but didn't display simple test in second line

Add pause 100 before GoSub timing

endif

lcdout $fe,$c0, dec3 day
pause 200
goto loop


lcdout $fe,$c0, dec3 date ,":", dec3 month ,":", dec3 year

[cyber88]
