open source can bus analyzer

written by Hubert Denkmair

building on windows

  • Qt Creator (Community Version is okay) brings everything you need
  • except for the PCAN libraries.
    • Get them from
    • Extract to .zip to src/driver/PeakCanDriver/pcan-basic-api
    • Make sure PCANBasic.dll (the one from pcan-basic-api/Win32 on a "normal" 32bit Windows build) is found when running cangaroo, e.g. by putting it in the same folder as the .exe file.
  • if you don't want Peak support, you can just disable the driver: remove the line "win32:include($$PWD/driver/PeakCanDriver/PeakCanDriver.pri)" from src/
  • if you want to deploy the cangaroo app, make sure to also include the needed Qt Libraries. for a normal release build, these are: Qt5Core.dll Qt5Gui.dll Qt5Widgets.dll Qt5Xml.dll


v0.2.1 unreleased

  • make logging easier
  • refactorings
  • scroll trace view per pixel, not per item (always show last message when autoscroll is on)

v0.2.0 released 2016-01-24

  • docking windows system instead of MDI interface
  • windows build
  • windows PCAN-basic driver
  • handle muxed signals in backend and trace window
  • do not try to extract signals from messages when DLC too short
  • can status window
  • bugfixes in setup dialog
  • show timestamps, log level etc. in log window

v0.1.3 released 2016-01-16

  • new can interface configuration GUI (missing a suid binary to actually set the config)
  • use libnl-route-3 for socketcan device config read
  • query socketcan interfaces for supported config options
  • new logging subsystem, do not use QDebug any more
  • some performance improvements when receiving lots of messages
  • bugfix with time-delta view: timestamps not shown when no previous message avail

v0.1.2 released 2016-01-12

  • fix device re-scan ("could not bind" console message)
  • fix some dbc parsing issues (signed signals, ...)
  • implement big endian signals

v0.1.1 released 2016-01-11

  • change source structure to better fit debian packaging
  • add debian packaging info

v0.1 released 2016-01-10

initial release \o/

raw message generator

  • provide a simple way to generate raw can messages

CanDB based generator
