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.
