node-blink1

A Node.js library for the blink(1) by ThingM.

For for info. on the blink(1), see todbot/blink1

Install

npm install node-blink1

Windows Users

node-blink1 depends on node-hid, a native module that uses node-gyp to build. node-gyp requires Python 2.7.3 in the PATH, and if you have Python 3 installed, you may have to modify your PATH for node-gyp to locate it.

See issue #3 for details.

Linux Users

If you encounter the following error while installing, you'll need new install of libusb.

libusb.h: No such file or directory compilation terminated.

For Debian and Ubuntu, install the package libusb-1.0-0.dev.

See issue #4 for details.

Usage

var Blink1 = require('node-blink1');

Get list of blink(1) devices connected:

Blink1.devices(); // returns array of serial numbers

Create blink(1) object without serial number, uses first device:

var blink1 = new Blink1();

Create blink(1) object with serial number, to get list of serial numbers use Blink1.devices():

var blink1 = new Blink1(serialNumber);

Get version:

blink1.version(callback(version));

Set colors

Fade to RGB, optional callback called after fadeMillis ms:

blink1.fadeToRGB(fadeMillis, r, g, b, [callback]); // r, g, b: 0 - 255

blink1.fadeToRGB(fadeMillis, r, g, b, [index, callback]); // r, g, b: 0 - 255
                                                         // index (mk2 only): 0 - 2

Set RGB:

blink1.setRGB(r, g, b, [callback]); // r, g, b: 0 - 255

Get RGB (mk2 only):

blink1.rgb([index,] callback(r, g, b));

Off:

blink1.off([callback]);

Other methods

Set server down (enable, disable), optional callback called after millis ms:

blink1.enableServerDown(millis, [callback]) // tickle

blink1.disableServerDown(millis, [callback]) // off

Play (start playing the pattern lines at the specified position):

blink1.play = function(position, [callback])

Play Loop (start playing a subset of the pattern lines at specified start and end positions. Specifying count = 0 will loop pattern forever):

blink1.playLoop = function(startPosition, endPosition, count, [callback])

Pause (stop playing the pattern line):

blink1.pause = function([callback])

Write pattern line (set the parameters for a pattern line, at the specified position):

blink1.writePatternLine(fadeMillis, r, g, b, position, [callback]) // r, g, b: 0 - 255

A simple example of this, used to flash red on & off is:

blink1.writePatternLine(200, 255, 0, 0, 0);
blink1.writePatternLine(200, 0, 0, 0, 1);
blink1.play(0);

Read pattern line (at the position):

blink1.readPatternLine(position, [callback])

Close (the underlying HID device):

blink1.close([callback]);
