CANopenDemo includes demo program with CANopenNode, tutorial and testing tools.
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/
CANopenDemo homepage is https://github.com/CANopenNode/CANopenDemo
Clone the project from git repository and get submodules:
git clone https://github.com/CANopenNode/CANopenDemo.git
cd CANopenDemo
git submodule update --init --recursive
There are several git submodules in CANopenDemo, see file .gitmodules. Some submodules, like CANopenLinux includes own git submodule CANopenNode, which is also updated with the above command.
If repositories are clean, the project can be updated by the following commands:
cd CANopenDemo
git pull
git submodule update --init --recursive
Use CANopenEditor to edit the object dictionary. Binaries are available, editor runs also in Linux with mono. Just run the EDSEditor.exe as a GUI application. You can open the demoDevice.xdd file, make changes according to your needs, export demoDevice.eds or demoDevice.md file, generate C source files for object dictionary (OD.h and OD.c), etc.
CANopen demoDevice can run on different target devices. It contains object dictionary with most common communication parameters and some additional manufacturer specific and device profile parameters. Simple example program run from application interface and shows some principles of CANopenNode usage.
See demo/README.md.
CANopenLinux is a CANopen stack running on Linux devices. It has full CANopen functionality with additional CANopen ASCII command interface (gateway) It can be used as a commander for other CANopen devices: NMT master, LSS master, SDO client, etc.
See CANopenLinux/README.md.
- tutorial/README.md - Configuration and basics.
- tutorial/LSS.md - Assigning Node-ID or CAN bitrate to devices, which support LSS configuration.
- tutorial/SDO.md - Further SDO access to the demoDevice parameters.
- tutorial/PDO.md - Demonstration of Process Data Objects.
Tests on Running CANopen network are implemented with two CANopenNode devices, running on CAN interface. First is CANopenLinux device with gateway interface, second is CANopen demoDevice.
Tests are run in Linux command line with Bash Automated Testing System - BATS, which is included in CANopenDemo as three git submodules.
See test/README.md.
CANopenNode.github.io is a git submodule with html documentation for CANopenDemo, CANopenNode and other devices. It is available also online at https://canopennode.github.io. Documentation is generated by doxygen. Documentation is generated separately for: CANopenNode, CANopenLinux (+ other target devices) and CANopenDemo. There are some links in the menu between different documentations. CANopenNode also contains tagfile which enables links to it from CANopenLinux and CANopenDemo.
To update the documentation of the CANopenNode.github.io install tools and generate all files:
sudo apt install doxygen graphviz pdf2svg
./update_docs.sh
