Servers for playing predefined sequences on a LPD8806 based LED strip connected to a RaspberryPi.

Project description

raspi.lpd8806

This package provides helpers to easily build fancy LED stuff with a “lpd8806 based digital addressable RGB led strip”:https://www.adafruit.com/products/306.

It consists of three parts.

API for sequences

To define a sequence you can use raspi.lpd8806.led_lib.Sequence as a base class.

On the class you can set, if the sequence should loop by setting loop = True.

You also have to define the used leds by the sequence on the class in a list leds = [12, 33, 44].

The actual sequence is defined in the __call__ method which has to return a generator yielding leds with their values for each frame.

You can set a single Led via raspi.lpd8806.led_lib.Led(index).on(red, green, blue), or set multiple Leds at once via Leds([12, 33, 44]).on({12: (r, g, b), 33: (r, g, b), 44: (r, g, b)}).

There is also a convenience method to set a predefined part of your strip by using raspi.lpd8806.led_lib.Strip(‘strip_name’).on(r, g, b).

Led, Leds and Strip instances of course also have off() methods to set all colors to 0.

Webserver

The Webserver serves a page with buttons to start or stop the sequences. It is started with the led_webserver script. See –help for details.

Queue Worker

The Queue worker processes the commands of the webserver and communicates with the LED strip. It can be started with the led_queue_worker script. See –help for details.
