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 :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, :interrupt Edge detection states for interrupts. EDGE_SETUP => 0, # reserved EDGE_FALLING => 1, EDGE_RISING => 2, EDGE_BOTH => 3, AUTHOR Steve Bertrand, COPYRIGHT AND LICENSE Copyright (C) 2016 by Steve Bertrand This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.18.2 or, at your option, any later version of Perl 5 you may have available.
