NAME

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

SYNOPSIS

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

# or...

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

# etc

DESCRIPTION

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,
