NAME RPi::WiringPi::Core - wiringPi Core Functions SYNOPSIS use RPi::WiringPi::Core; my $core = RPi::Wiring::Core->new; DESCRIPTION This is an XS-based module, and requires wiringPi to be installed. It provides Perl method access to (at this time, most of) the wiringPi Core along with a few of its system functions. Although this module can be used directly, it's generally used as a base class for other modules. METHODS new() Returns a new RPi::WiringPi::Core object. setup() See wiringPi setup functions for for information on this method. setup_sys() See wiringPi setup functions for for information on this method. setup_gpio() See wiringPi setup functions for for information on this method. pin_mode($pin, $mode) Puts the GPIO pin in either INPUT or OUTPUT mode. Parameters: $pin Mandatory: The GPIO pin number, using wiringPi's pin number representation. $mode Mandatory: 0 to have the pin listen on INPUT, and 1 for OUTPUT. read_pin($pin); Returns the current state (HIGH/on, LOW/off) of a given pin. Parameters: $pin Mandatory: The wiringPi number representation of the GPIO pin. write_pin($pin, $state) Sets the state (HIGH/on, LOW/off) of a given pin. Parameters: $pin Mandatory: The wiringPi number representation of the GPIO pin. $state Mandatory: 1 to turn the pin on (HIGH), and 0 to turn it LOW (off). pull_up_down($pin, $direction) Enable/disable the built-in pull up/down resistors for a specified pin. Parameters: $pin Mandatory: The wiringPi number representation of the GPIO pin. $direction Mandatory: 2 for UP, 1 for DOWN and 0 to disable the resistor. pwm_write($pin, $value) Sets the Pulse Width Modulation duty cycle (on time) of the pin. Parameters: $pin Mandatory: The wiringPi number representation of the GPIO pin. $value Mandatory: 0 to 1024. 0 is 0% (off) and 1024 is 100% (fully on).
