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 <
http://wiringpi.com/reference/setup>
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,
