LCD display not working properly

[bbazor]

I didn't see a Chk_KEYPAD subroutine included in your code. Do you have one?

[scarroll01]

If this is for password entry, do you even WANT to display the characters that are entered? Better to handle it like MS Windows and display asterisks.

Just a thought,

Chk_KEYPAD subroutine has been used at gosub

The problem is that the four numbers are not displayed at 1st , 2nd , 3rd ,4th positions in one line

Let's analyze one of your LCDOUT statements...

Lcdout $fe, $c0+1,1,$0f, #key

LCDOUT - the command
$fe - send an instruction
$c0 + 1 - the position
1 - clear the display which basically resets the display back to square one
$0f - programmable character
#key - a variable
....
See a problem here?

I deleted "1 " -(clear the display...) and tried the above code using gosub four times for the four diff. positions but the display shows a question mark at 16th position on first line and stops. why?

please help.

Increase the startup pause to 1 second...increase your LCD_commandus and LCD_dataus to higher values, try it again and see what happens.

NOPE,

if you use 1 without $FE before, it will try to print ASCII decimal character 1, same for $0F. If you want to mask you data with asterix, just use "*" in your lcdout and forget the #key.
MAybe you could find some tips in the following

Are you saying that:
LCDOUT $fe , 1 , $80 , "HELLO"
is different from:
LCDOUT $fe , 1 , $fe , $80 , "HELLO" ???

I guess I just never noticed, or tried it.
