The Very Simple Control Protocol (VSCP) ^[1] is a free automation protocol suitable for all sorts of automation task where building- or home-automation is in the main focus.

Its main advantage is that each VSCP-node can work completely autonomous, being part of distributed network of other nodes.

VSCP is independent from the physical layer (e.g. CAN bus, Ethernet, RS-485, RS-232, MiWi) connecting the individual nodes to form the automation network bus. On the bus there can be nodes reading switches, controlling lighting, blinds, windows or information displays, broadcasting physical measurements (e.g. temperature, luminosity, power consumption, etc.), multimedia control, burglar- or fire-alarm, etc.

There is a subset of the protocol (Level I) that is very much tailored to the CAN bus and resource restricted microcontrollers. Protocol Level II is designed for Ethernet (UDP, TCP and own Ethernet-type Raw-Ethernet) and wireless physical layers. All share the same common message fields and framework and can be connected through gateways.
