This patch adds a fourth string field in the can logfile format. This new field contains the rx/tx direction information R/T as the first entry (only one character separated from the CAN frame by space). To generate the logfile format with this extra field candump has to be called with the '-x' option for extra message infos, e.g. 'candump -x -l can0' or 'candump -x -L can0' log2asc and asc2log are extended to support the direction information but still support the previous format without direction information. The format extension does not affect legacy tools, e.g. the existing canplayer ignores this extra information and does not need to be changed. Therefore the existing logfiles remain valid and usable. The extra message infos will be colon separated when there's need for additional content beyond the rx/tx direction information, e.g. R:xx:yyy Suggested-by: Pallavi Revanna https://github.com/brpallu Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> |

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
- 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
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
