NAME

    RPi::WiringPi::Core - wiringPi Core Functions

SYNOPSIS

      use RPi::WiringPi::Core;
    
      my $core = RPi::Wiring::Core->new;

DESCRIPTION

    This module provides Perl method access to the wiringPi Core
    <http://wiringpi.com/reference/core-functions> along with a few of its
    system functions.

    Although this module can be used directly, it's generally used as a
    base class for other modules.

METHODS

 new()

    Returns a new RPi::WiringPi::Core object.

 setup()

    See wiringPi setup functions <http://wiringpi.com/reference/setup> for
    for information on this method.

 setup_sys()

    See wiringPi setup functions <http://wiringpi.com/reference/setup> for
    for information on this method.

 setup_gpio()

    See wiringPi setup functions <http://wiringpi.com/reference/setup> for
    for information on this method.

 pin_mode($pin, $mode)

    Puts the GPIO pin in either INPUT or OUTPUT mode.

    Parameters:

        $pin

    Mandatory: The GPIO pin number, using wiringPi's pin number
    representation.

        $mode

    Mandatory: 0 to have the pin listen on INPUT, and 1 for OUTPUT.

 pull_up_down($pin, $direction)

    Enable/disable the built-in pull up/down resistors for a specified pin.

    Parameters:

        $pin

    Mandatory: The wiringPi number representation of the GPIO pin.

        $direction

    Mandatory: 2 for UP, 1 for DOWN and 0 to disable the resistor.

 read_pin($pin);

    Returns the current state (HIGH/on, LOW/off) of a given pin.

    Parameters:

        $pin

    Mandatory: The wiringPi number representation of the GPIO pin.

 write_pin($pin, $state)

    Sets the state (HIGH/on, LOW/off) of a given pin.

    Parameters:

        $pin

    Mandatory: The wiringPi number representation of the GPIO pin.

        $state

    Mandatory: 1 to turn the pin on (HIGH), and 0 to turn it LOW (off).
