README.md

Version 2.0.2

This is the usermode daemon for the Intrepid Control Systems SocketCAN support. This daemon requires that intrepid.ko is loaded on your system.

  1. Build and load the kernel module follwowing the instructions in intrepid-socketcan-kernel-module.

  2. Install the dependencies needed. These are CMake 3.2+, GCC 4.8+, git, libusb-1.0-0-dev, and libpcap.

On Ubuntu or other Debian-based systems, run sudo apt install git cmake gcc libusb-1.0-0-dev libpcap-dev build-essential.

  1. Clone this repository recursively by running git clone --recursive https://github.com/intrepidcs/icsscand.git

  2. Switch into the cloned directory, cd icsscand

  3. Make a build directory and switch into it, mkdir build && cd build

  4. Invoke CMake, cmake .. -DCMAKE_BUILD_TYPE=Release

  5. Build the daemon, make

  6. The daemon is now available as libicsneo-socketcan-daemon

  7. Start the daemon up to begin connecting to devices. Use sudo ./libicsneo-socketcan-daemon. If you're happy with the results and would like to run in the background, run sudo ./libicsneo-socketcan-daemon -d to run in daemon mode.

  8. CAN interfaces will have been created, but are "down" or, in other words, not enabled for transmit and receive yet. You can see them with ip link. They will be labelled can0, can1, and etc. They will have an alias listed which corresponds to the serial number of the device and network on that device.

  9. Enable the CAN interface with sudo ip link set up can0, replacing can0 with whichever interface you'd like to enable

  10. You can now use any SocketCAN application with this interface. A good package for testing is the can-utils package. You can get this package with sudo apt install can-utils. A good testing tool which comes with this package is candump. Running candump can0 will print a line for every incoming frame.
