NAME

RPi::WiringPi::Constant - Constant variables for RPi::WiringPi

SYNOPSIS

    # THIS DISTRIBUTION IS DEPRECATED. PLEASE SEE THE "DESCRIPTION" SECTION

    use RPi::WiringPi::Constant (:all);

    # or...

    use RPi::WiringPi::Constant (:pinmode);

    # etc

DESCRIPTION

THIS DISTRIBUTION/MODULE IS DEPRECATED. It'll continue to install and work, but it will not be updated or maintained further.

PLEASE USE RPi::Const FOR ANY PROJECTS MOVING FORWARD. If current projects break due to the use of this distribution, please switch over to RPi::Const.

This module optionally exports selections or all constant variables used within the RPi::WiringPi suite.

CONSTANT EXPORT TAGS

These are the individual grouping of export tags. The :all tag includes all of the below.

:mode

Setup modes. This is what determines which pin numbering scheme you're using. See wiringPi setup modes for details.

    RPI_MODE_WPI      =>  0, # wiringPi scheme
    RPI_MODE_GPIO     =>  1, # GPIO scheme
    RPI_MODE_GPIO_SYS =>  2, # GPIO scheme in SYS mode
    RPI_MODE_PHYS     =>  3, # physical pin layout scheme
    RPI_MODE_UNINIT   => -1, # setup not yet run

:pinmode

Pin modes.

    INPUT            => 0,
    OUTPUT           => 1,
    PWM_OUT          => 2,
    GPIO_CLOCK       => 3,
    SOFT_PWM_OUTPUT  => 4,  # reserved
    SOFT_TONE_OUTPUT => 5,  # reserved
    PWM_TONE_OUTPUT  => 6,  # reserved

:altmode

Pin ALT modes.

    ALT0 => 4,
    ALT1 => 5,
    ALT2 => 6,
    ALT3 => 7,
    ALT4 => 3,
    ALT5 => 2,

:pull

Internal pin pull up/down resistor state.

    PUD_OFF  => 0,
    PUD_DOWN => 1,
    PUD_UP   => 2,

:state

    HIGH => 1,
    LOW  => 0,
    ON   => 1,
    OFF  => 0,

:pwm_mode

The modes the PWM can be set to.

    PWM_MODE_MS  => 0,
    PWM_MODE_BAL => 1,

:interrupt

Edge detection states for interrupts.

    EDGE_SETUP   => 0,  # reserved
    EDGE_FALLING => 1,
    EDGE_RISING  => 2,
    EDGE_BOTH    => 3,
