RPi::Const - Constant variables for embedded programming, including the RPi:: family of modules
use RPi::Const (:all); # or... use RPi::Const (:pinmode); # etc
This module optionally exports selections or all constant variables used within the RPi::WiringPi suite.
RPi::WiringPi
These are the individual grouping of export tags. The :all tag includes all of the below.
:all
Setup modes. This is what determines which pin numbering scheme you're using. See wiringPi setup modes for details.
