NAME

RPi::WiringPi::Board - Access and manipulate Raspberry Pi board attributes

SYNOPSIS

    use RPi::WiringPi;
    
    my $pi = RPi::WiringPi->new;

    my $board = $pi->board;

    my $board_revision = $board->rev;

    my $pin_num = 5;
    my $wpi_to_gpio = $board->wpi_to_gpio($pin_num);
    my $phys_to_gpio = $board->phys_to_gpio($pin_num);

    print "rev: $board_revision\n" .
          "wiringPi pin $pin_num translated to gpio pin num: $wpi_to_gpio\n" .
          "physical pin $pin_num translated to gpio pin num: $phys_to_gpio";

    # change the Pulse Width Modulation (PWM) range maximum

    $board->pwm_range(512);

DESCRIPTION

Through a RPi::WiringPi object, creates objects that has direct access to various attributes on the Rasperry Pi board itself.

METHODS

new()

Returns a new RPi::WiringPi::Board object.

rev()

Returns the revision of the Pi board.

wpi_to_gpio($pin_num)

Converts a pin number from wiringPi notation to Broadcom (BCM) notation, and returns the BCM representation.

Parameters:

    $pin_num

Mandatory: The wiringPi representation of a pin number.

phys_to_gpio($pin_num)

Converts a pin number as physically documented on the Raspberry Pi board itself to Broadcom (BCM) notation, and returns it.

Parameters:

    $pin_num

Mandatory: The pin number printed on the physical Pi board.
