Brick Daemon (brickd)

The Brick Daemon is a daemon (or service on Windows) that acts as a bridge between the Bricks/Bricklets and the API bindings for the different programming languages.

The daemon routes data between the USB connections and TCP/IP sockets. When using the API bindings a TCP/IP connection to the daemon is established. This concepts allows the creation of bindings for almost every language without any dependencies. Therefore it is possible to program Bricks and Bricklets from embedded devices that only support specific languages, such as smart phones.

Additionally it is possible to separate the machine running the Brick Daemon from the machine running the user code. This allows e.g. a Brick connected to a PC to be controlled from a smart phone or over the Internet from another PC.
