CANopenSocket is a collection of CANopen tools and examples.

It is based on CANopenNode, which is free and open source CANopen Stack and is included as a git submodule.

CANopen is the internationally standardized (EN 50325-4) (CiA301) CAN-based higher-layer protocol for embedded control system. For more information on CANopen see http://www.can-cia.org/

Getting or updating the project

Clone the project from git repository and get submodules:

git clone https://github.com/CANopenNode/CANopenSocket.git
cd CANopenSocket
git submodule init
git submodule update

Update the project:

cd CANopenSocket
# make sure, project is clean (git status); changes should be committed (git gui)
git pull # or: git fetch -> gitk --all (inspect the changes) -> git merge
# git submodule init # if new git modules
git submodule update

Get/update other tools (EDSeditor):

cd tools
./get_tools.sh

Getting started

First information is in CANopenNode/README.

Basic getting started guide is available in CANopenNode/doc/gettingStarted.md. If everything works there as expected, with virtual or real CAN, then CANopen network is established. With at least basic operation of: CAN reception, transmission, NMT, Heartbeat, Service Communication Objects (SDO).

Next is Basic CANopen Device example program with source code, custom Object Dictionary access functions and advanced CANopen gateway communication. See basicDevice/README.md.
