NAME

  Device::WebIO::Device::DigitalOutput - Role for general-purpose digital output

REQUIRED METHODS

output_pin_count

    output_pin_count();

Return the number of output pins.

output_pin

    output_pin( $pin, $value );

Set the given value for the given pin.

set_as_output

    set_as_output( $pin );

Set the given pin as an output pin.

is_set_output

    is_set_output( $pin );

Returns true if the given pin is set as an output pin.

PROVIDED METHODS

output_port

    output_port( $bitstring );

Set all the output pins at once with a bitstring.

The default implementation sets this by iterating through using output_pin(). Many platforms have an efficient way of setting all the pins at once, so you may wish to override this.
