The first three patches are from PR https://github.com/linux-can/can-utils/pull/629 that was stuck due to the review process. The review questions of commit https://github.com/linux-can/can-utils/pull/629#pullrequestreview-4361812324 have been addressed in this PR (see commit message) The most important fix that has an impact on the data structures on the CAN bus is the last one ("isobusfs: pack the protocol structures"). "The isobusfs protocol structures describe the message layout defined in ISO 11783-13 but were not packed. The compiler added padding bytes in front of 16/32 bit values which follow an odd number of bytes, e.g. the Read File Request (8 bytes according to C.3.5.2) had a size of 10 bytes and the count value at the wrong position. Server and client of the can-utils used the same structures and understood each other but the messages were not compatible to other ISOBUS devices." So this has to be checked and reviewed carefully as it breaks the former protocol of can-utils (but likely fits the rest of the world).
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 and serves them
- 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)
- canerrsim : CAN error message simulator
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
ISOBus File server tools
- isobusfs-cli : ISOBus file client
- isobusfs-srv : ISOBus file server
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
appfolder, addadd_subdirectory(can-utils)to yourCMakeLists.txtfile aftercmake_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_PREFIXie.CC=clang cmake -DCMAKE_INSTALL_PREFIX=./out .. && make install
