NAME
    Device::BlinkyTape - Control a BlinkyTape led strip

SYNOPSIS
        use Device::BlinkyTape::WS2811; # BlinkyTape uses WS2811
        my $bb = Device::BlinkyTape::WS2811->new(dev => '/dev/tty.usbmodem');
        # Set all led pixels on full white
        $bb->all_on();
        # Set all led pixels off
        $bb->all_off();

        # Send a white pixel (RGB 255/255/255).
        # Pixels are sent one by one from left to right.
        $bb->send_pixel(255,255,255);
        $bb->send_pixel(5,5,5);
        # Show all sent pixels and reset send_pixel to the first pixel.
        $bb->show();

  dev
    The device where your usb ledstrip is at. Defaults to /dev/tty.usbmodem.

  port
    Instead of giving the device you can create the instance of this module
    by directly giving it a Device:SerialPort object. By default the
    Device::SerialPort object is created from the device given in the 'dev'
    parameter.

  gamma
    Specify the gamma correction. Defaults to [1,1,1]

  led_count
    Specify the led count, counting from 1. The default is 60.

  simulate
    Specify if the module should simulate a BlinkyTape onscreen instead of
    using one in the usb port. Defaults to 0 (false). If this is true then
    the port and dev parameters have no effect.

  sleeptime
    Sending data too fast freezes the BlinkyTape. Sleeping for 30
    microseconds between each byte makes sure the atmega processor of the
    BlinkyTape can keep up with the incoming data.

  all_on
    Turns all leds on.

  all_off
    Turns all leds off.

  send_pixel(r,g,b)
    Send the RGB value for the next pixel. Values 0-254 are sent as is,
    value 255 is converted to 254.

  show
    Shows the sent pixels and resets the send_pixel to the first led pixel
    of the strip. This is done by sending a single 255 value byte to the led
    strip.

ABOUT BLINKYTAPE
    Blinkytape is a controllable led strip available at
    http://blinkiverse.com/blinkytape/

USING THE MODULE ON OS X WITHOUT OWNING A BLINKYTAPE
    This module comes with a BlinkyTape simulator. Install X11 server to use
    the simulator: http://xquartz.macosforge.org/landing/

BUGS
    The device is not yet available so the module has been implemented by
    inspecting partly undocumented and unfinished code in other languages.
    Feel free to file any bug reports in Github, patches welcome.
