CANopenNode
A free and open-source ANSI C implementation of the CANopen protocol stack for embedded control systems.
What is CANopenNode?
CANopenNode is a free and open-source CANopen protocol stack written in ANSI C for embedded control systems. It implements the standardized CANopen higher-layer protocol, enabling devices to communicate over CAN networks with features like Object Dictionary management, PDO/SDO communication, and network synchronization. It solves the problem of implementing robust, standardized industrial communication in resource-constrained microcontroller environments.
Embedded systems engineers and developers working on industrial automation, automotive, or robotics projects that require CANopen communication. It's particularly suited for those targeting microcontrollers from 16-bit and above, with or without an RTOS.
Developers choose CANopenNode because it's a mature, conformance-tested open-source stack that offers full CANopen protocol support while being highly portable and efficient. Its object-oriented design in ANSI C allows for flexible integration and customization across diverse hardware platforms.
