Changing Startup Screen in Perl (Linux)

Hi!

I'd like to change the startup screen on a LK202-25WB (installed on a linux system). I' using the following perl code.

open(LCD, ">/dev/lcd") or die "Can't open (write) to /dev/lcd: $!\n";
print LCD chr(254), chr(64), " WELCOME! BOOTING SYSTEM ";
close(LCD);

Unfortunately this code is not working :(

Other thinks work fine. I can clear the display, turn backlight on or off, ...

Do i need to use the remember function to set the startup screen?

Maybe somebody can help me.

Thanks!

Regards,
Robert

The set startup screen expects a FULL screen. A partial screen won't do. So you are going to need to send 40 characters after the initial 254/64 command. Give that a shot and let us know if that works.
