NAME

Device::Pertelian - a driver for the Pertelian X2040 USB LCD

VERSION

Version 0.01

SYNOPSIS

If you have a Pertelian X2040 USB LCD screen, then you can do things with it.

use Device::Pertelian;

my $lcd = Device::Pertelian->new('/dev/ttyUSB0');
$lcd->clearscreen();

# write to the top row
$lcd->writeline(0, "Hello, world!");
...

METHODS

new

The constructor accepts one parameter, $device, which is a path in /dev. You may find it out from your logs.

clearscreen

This function does a simple thing -- clears all the 4 lines of the screen.

writeline

This function takes two parameters, $row and $text. The screen has 4 rows, so you may pass a number from 0 to 3 as $row and the $text should be under 20 characters, that is the width of the screen.
