NAME

Device::NTCChip::GPIO - Control the GPIO pins on the original NTC Chip

VERSION

version 0.101

SYNOPSIS

This module provides method to control the GPIO pins on the original NTC Chip. It first scans the /sys/class/gpio location to map the GPIO addresses, then provides methods to turn the pins on or off or read them.

    use Device::NTCChip::GPIO;

    # Initialise the GPIO interface
    my $gpio = Device::NTCChip::GPIO->new;

    # take the appropriate action
    if ( $action eq "on" ){
        $gpio->relay_on($pin);
    } elsif ( $action eq "off" ){
        $gpio->relay_off($pin);
    } else {
        my $error = "Unknown facility mode: $action";
        die $error;
    }

NTC has gone into liquidation since this module was first written, but it is being made available in the hope it will be of some use to somebaody. No original NTC domains exist anymore, but there is this community site that provide a lot of info: http://www.chip-community.org/index.php/Main_Page.

METHODS

turn_on

Turn a pin on (set it high)

    $gpio->turn_on(3);

turn_off

Turn a pin turn off (set it low)

    $gpio->turn_off(3);

relay_on

Turn a pin off (set it low)

    $gpio->relay_on(3);

relay_off

Turn a pin on (set it high)

    $gpio->relay_off(3);

read

Read whether a pin is on or off (high or low).

    my $value = $gpio->read(3);
