Controller Area Network (CAN)

The Controller Area Network (CAN) node-type allows the exchange of signals via a CAN bus.

Prerequisites

This node-type does not have any special library dependencies. It is always available.

Implementation

The source code of the node-type is available here: https://git.rwth-aachen.de/acs/public/villas/node/blob/master/lib/nodes/can.cpp

Configuration

Todo:

Finish CAN node-type documentation

Example
