Beaglebone BlinkM

First, let's import Cylon:

var Cylon = require('cylon');

Now that we have Cylon imported, we can start defining our robot

Cylon.robot({

Let's define the connections and devices:

  connections: {
    beaglebone: { adaptor: 'beaglebone' }
  },

  devices: {
    pixel: { driver: 'blinkm', pin: 'P9_20' }
  },

Now that Cylon knows about the necessary hardware we're going to be using, we'll tell it what work we want to do:

  work: function(my) {
    my.pixel.stopScript();

    // You can pass a callback to all blinkm functions as the last param,
    // If you do the command would be executed asynchronously.
    // For write operations you get an (err) param passed back,
    // nucylondefined for success, and containing the error y any encountered.
    //
    // Write BlimkM commands.
    my.pixel.goToRGB(255, 0, 0);
    my.pixel.fadeToRGB(0, 255, 0);
    my.pixel.fadeToHSB(100, 180, 90);
    my.pixel.fadeToRandomRGB(0, 0, 255);
    my.pixel.fadeToRandomHSB(100, 180, 90);
    my.pixel.playLightScript(1, 0, 0);
    my.pixel.stopScript();
    my.pixel.setFadeSpeed(50);
    my.pixel.setTimeAdjust(50);

    // For read commands you get (err, data) passed back to the callback,
    // data contains the read data buffer, in case of Sync call (no callback)
    // you get a regular return.
    var color = my.pixel.getRGBColor();

    if (typeof err === "undefined" || err === null) { console.log(color); }

    // Example getting the color using async call and a callback
    my.pixel.getRGBColor(function(err, data) {
      if (err == null) { console.log(data); }
    });

Now that our robot knows what work to do, and the work it will be doing that hardware with, we can start it:

}).start();
