Advanced tools
Node-RED node based on socketcan for reading a KCD file and handeling CAN-messages sent and received for this.
Run the following command in your Node-RED user directory - typically ~/.node-red
npm install node-red-contrib-can
You will need to have can-utils installed on your machine. Since this package is only available for unix systems you will need a unix machine to run this. sudo apt-get install can-utils should work in ubuntu.
The node can be 'enabled' or 'disabled' by sending a 'msg.can' message of 'enable' or 'disable'. This makes it easy to to halt or start can messages while the flow is running or based of external logic.
The node can also be configured to send a CAN message any time there is an update to the node, or only on change.
Since this only works with kayak (kcd) files I would recommend having a look at canmatrix which is a python tool to convert between different standards.
Thanks to sebi2k1 for his excellent NodeJs wrapper around socketcan. ebroecker for his canmatrix convertion tool.
