The display_text is just one of the functions I have in Display.pm

sub display_text
{

my ($text) = @_;

print DISPLAY "$text\n";

}

I tried what you suggested just:

print DISPLAY "$char\n";

but that doesn't put anything at all to the screen.

I don't understand it, I've been trying for ages ...

Hi all,

I wonder if some could give me a few pointers on where I might be going wrong. I'm trying to set up some custom characters and can't get the unit to write anything to the screen.

This is the perl code I'm using:

my $set = sprintf "%cN%c%c%c%c%c%c%c%c%c", 0xfe, 0x07,
0x04, 0x0e, 0x1f ...
