VSCP Framework Basics and IoT Operations

vscp iot framework protocol event driven

This page covers the basics of the VSCP Framework and describes its working operations within the Internet of Things (IoT).

VSCP stands for Very Simple Control Protocol.

It functions more as a framework than a protocol.
VSCP facilitates interaction between devices at the application layer.
VSCP is compatible with various protocol mechanisms, including: CAN, Ethernet, RS232, TCPIP, Zigbee, Bluetooth, USB, GPRS, etc.
VSCP employs an event-driven format.
It supports global identifiers for nodes, allowing a node to be identified regardless of its location worldwide.
It incorporates a register model to provide a flexible, common interface for node configuration.
It offers a model for controlling the functionalities of each node.

When an event occurs, it is broadcast to all other nodes on the network.
Each node then determines whether the received event needs to be processed.
The final decision is based on the node’s decision matrix. This matrix consists of a number of “if conditions.” The evaluation of these conditions depends on the fields present in the VSCP datagram that is broadcast to the network.
