rgb-led-matrix/controllers/EMULATOR.js

Universal RGB Matrix controller for Node.js. Supports realtime frame streaming (eg. Ambilight). BlinkStick RGB LED controller given as example.

//Device driver for Emulator (arbitrary number LEDS per channel)
//Only the following methods are required to support any controller:
//turnOff()   - turns controller off
//setColors() - sends RGB data to controller
//getMaxSize()- Maximum number of LEDs supported
//TODO: node-pixel/johnny5 integration for specific devices

const server    = require('../webserver/server.js');
var   device    = null;
var   busy      = false;
var   MAX_SIZE  = Number.MAX_SAFE_INTEGER;  
var   power     = false;
