Oliver Hartkopp 5f764e73bf cansend: update CAN FD check to cope with CAN XL interfaces 
The check for CAN FD capable interfaces only checked for CANFD_MTU to
enable the generation of CAN FD frame content. As CAN XL capable CAN
interfaces are able to handle CAN FD frames too the check has to be
extended for CANXL_MTU interfaces.

SocketCAN userspace utilities and tools

This repository contains some userspace utilities for Linux CAN subsystem (aka SocketCAN):

Basic tools to display, record, generate and replay CAN traffic

  • candump : display, filter and log CAN data to files
  • canplayer : replay CAN logfiles
  • cansend : send a single frame
  • cangen : generate (random) CAN traffic
  • cansequence : send and check sequence of CAN frames with incrementing payload
  • cansniffer : display CAN data content differences

CAN access via IP sockets

  • canlogserver : log CAN frames from a remote/local host
  • bcmserver : interactive BCM configuration (remote/local)
  • socketcand : use RAW/BCM/ISO-TP sockets via TCP/IP sockets
  • cannelloni : UDP/SCTP based SocketCAN tunnel

CAN in-kernel gateway configuration

  • cangw : CAN gateway userspace tool for netlink configuration

CAN bus measurement and testing

  • canbusload : calculate and display the CAN busload
  • can-calc-bit-timing : userspace version of in-kernel bitrate calculation
  • canfdtest : Full-duplex test program (DUT and host part)

ISO-TP tools ISO15765-2:2016 for Linux

  • isotpsend : send a single ISO-TP PDU
  • isotprecv : receive ISO-TP PDU(s)
  • isotpsniffer : 'wiretap' ISO-TP PDU(s)
  • isotpdump : 'wiretap' and interpret CAN messages (CAN_RAW)
  • isotpserver : IP server for simple TCP/IP <-> ISO 15765-2 bridging (ASCII HEX)
  • isotpperf : ISO15765-2 protocol performance visualisation
  • isotptun : create a bi-directional IP tunnel on CAN via ISO-TP

J1939/ISOBus tools

  • j1939acd : address claim daemon
  • j1939cat : take a file and send and receive it over CAN
  • j1939spy : spy on J1939 messages using SOC_J1939
  • j1939sr : send/recv from stdin or to stdout
  • testj1939 : send/receive test packet

Follow the link to see examples on how this tools can be used: Kickstart guide to can-j1939 on linux

Log file converters

  • asc2log : convert ASC logfile to compact CAN frame logfile
  • log2asc : convert compact CAN frame logfile to ASC logfile
  • log2long : convert compact CAN frame representation into user readable

Serial Line Discipline configuration (for slcan driver)

  • slcan_attach : userspace tool for serial line CAN interface configuration
  • slcand : daemon for serial line CAN interface configuration
  • slcanpty : creates a pty for applications using the slcan ASCII protocol

CMake Project Generator

  • Place your build folder anywhere, passing CMake the path. Relative or absolute.
  • Some examples using a build folder under the source tree root:
  • Android : cmake -DCMAKE_TOOLCHAIN_FILE=~/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_PLATFORM=android-21 -DANDROID_ABI=armeabi-v7a .. && make
  • Android Studio : Copy repo under your project's app folder, add add_subdirectory(can-utils) to your CMakeLists.txt file after cmake_minimum_required(). Generating project will build Debug/Release for all supported EABI types. ie. arm64-v8a, armeabi-v7a, x86, x86_64.
  • Raspberry Pi : cmake -DCMAKE_TOOLCHAIN_FILE=~/rpi/tools/build/cmake/rpi.toolchain.cmake .. && make
  • Linux : cmake -GNinja .. && ninja
  • Linux Eclipse Photon (Debug) : CC=clang cmake -G"Eclipse CDT4 - Unix Makefiles" ../can-utils/ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_ECLIPSE_VERSION=4.8.0
  • To override the base installation directory use: CMAKE_INSTALL_PREFIX ie. CC=clang cmake -DCMAKE_INSTALL_PREFIX=./out .. && make install
