pcan-linux-installation

ROS support for sick line guidance sensors has been developed and tested using PEAK CAN adapter for the CAN communication. This is a quick howto install linux driver for the pcan usb adapter.

Installation

The following installation is recommended:

  1. Download PCAN-View for Linux from https://www.peak-system.com/linux/ or https://www.peak-system.com/quick/ViewLinux_amd64/pcanview-ncurses_0.8.7-0_amd64.deb and install:

sudo apt-get install libncurses5
sudo dpkg --install pcanview-ncurses_0.8.7-0_amd64.deb

  2. If you're running ROS in a virtual machine, make sure the usb-port for the PCAN-USB-adapter is connected to your VM.

  3. Download and unzip peak-linux-driver-8.17.0.tar.gz from https://www.peak-system.com/quick/PCAN-Linux-Driver

  4. Install the linux driver and required packages:

cd peak-linux-driver-8.17.0
# install required packages
sudo apt-get install can-utils
sudo apt-get install gcc-multilib
sudo apt-get install libelf-dev
sudo apt-get install libpopt-dev
sudo apt-get install tree
# build and install pcan driver
make clean
make NET=NETDEV_SUPPORT
sudo make install
# install the modules
sudo modprobe pcan
sudo modprobe can
sudo modprobe vcan
sudo modprobe slcan
# setup and configure "can0" net device
sudo ip link set can0 type can
sudo ip link set can0 up type can bitrate 125000 # configure the CAN bitrate, f.e. 125000 bit/s
# check installation
./driver/lspcan --all       # should print "pcanusb32" and pcan version
tree /dev/pcan-usb          # should show a pcan-usb device
ip -a link                  # should print some "can0: ..." messages
ip -details link show can0  # should print some details about "can0" net device

Example output after successfull installation of a pcan usb adapter:
