The AnyPixel backend consists of four applications which work together to provide an interface between the javascript-driven AnyPixel apps (the frontend) and the physical display hardware.

• AppServer - A node.js server which locally hosts the AnyPixel apps.

• ChromeBridge - A Chrome app which displays AnyPixel apps and handles the communication between the AppServer apps and the physical display hardware.

• UdpManager - A node.js app which distributes data packets from ChromeBridge to the individual hardware components.

• Emulator - A Chrome app for debugging, which simulates the network communications between ChromeBridge and the physical display hardware.

These instructions assume a basic familiarity with the command line of your particular system. For a good introduction to the command line, check out The Command Line Crash Course.
