STRATUM

NodeJS Server / esp8266+W5500 Node

You can find a basic usage in demo.js

Install

npm install --save hemisphere-project/stratum-hnode

Basic usage

var hnode = require('hnode')();   // load and instanciate the library
var server = new hnode.Server();  // instantiate a server
server.start();                   // start the server

Options

var hnode = require('hnode')({
  // This are the default options
  PORT_SERVER: 3737,            // Working UDP port
  TIME_TICK: 100,               // Watchdog timer ms
  TIME_OFFLINE: 1000,           // Offline Time
  TIME_GONE: 3000,              // Gone Time
  NLEDS_STRIPS: 90,             // N leds per strips
  NSTRIPS_CLIENT: 4,            // N strips per client
  log : msg => console.log(msg) // custom log function (to write in file, etc)
});
var server = new hnode.Server()
server.start()

API

Server methods:

.getNodeByIP( ip )
return a Node or undefined

.getNodeByName( name )
return a Node or undefined

.getAllNodes()
return an array with all known Nodes

.setAll( rgb )
apply one color (rgb array) to every leds, rgb = [r,g,b]

.blackout()
switch off every leds

Server events:

.on('newnode', function(node){ ... })
triggered when a new Node is discovered

.on('tick', function(node){ ... }) server ticker, can be use as main sequencer

Node methods:

.setLed( strip, led, rgb )
apply rgb array to a specific led, rgb = [r, g, b] array[3]

.setStrip( led, rgbs )
apply rgbs array of array to a strip, rgbs = [ [r, g, b], [r, g, b], ... ] array[NUM_LEDS_PER_STRIP][3]

.setAll( rgbs )
apply a whole set of 4 strips, rgbs = [ [ [r, g, b], [r, g, b], ... ], ... ] array[NSTRIPS_PER_CLIENTS][NUM_LEDS_PER_STRIP][3]

.randomize()
randomize all values of the node's leds

Node attributes (read-only):

.name
.ip

Node events:

.on('start', function(node){ ... })
triggered when a node is started

.on('online', function(node){ ... })
triggered when a node goes online

.on('offline', function(node){ ... })
triggered when a node goes offline

.on('stop', function(node){ ... })
triggered when a node is stopped
