Free CAN Bus Software: CANvas – Configure, Stream, Convert


CANvas is our 100% free supporting software
tool for the CAN logger CLX000 series of CAN bus data loggers. In this video we provide a brief overview
of the main features, including Configuration, Live Streaming and Data Conversion. Let’s start with Configuration:
The CAN logger CLX000 is plug-and-play so you can log data out of the box. However, it is also highly configurable – and
CANvas is a great tool for doing so! When you open the configuration tab, you’ll
be able to choose a range of options. First of all, you can specify a logger ID,
data seperator and a split limit to create a new log file for example every time the
file becomes larger than 100 MB. You can also specify bit rate including our
convenient auto-detection feature, as well as put the logger in silent/listen only mode. For the CAN logger CL2000 and CL3000 models, you
can also customize the timestamp format and adjust the real-time clock to match your timezone. Additional great features include cyclical
logging to delete the oldest files when the SD card is full or the hearbeat signal that
let’s you receive a status message every second from the logger. You can also set up a control signal to turn
logging on or off based on a specific CAN message trigger. A key feature of the CAN logger CLX000 series
is the ability to transmit messages to the CAN bus. The logger can transmit up to 20 custom CAN
messages, making it easy to – for example – log OBD2 vehicle data parameters. In case you wish to only log certain parameters,
you can also set up message filtering using CANvas. And finally, if you’re the lucky owner of
a CAN logger CL3000 with WiFi, you can configure the WiFi settings easily in CANvas, incl. Access Point mode, Station mode and settings
for the web server log file interface. Once you’re done configuring the logger,
simply export the CONFIG file to the SD card and eject the logger from the USB. The second major feature of CANvas is real-time
streaming. All CAN logger CLX000 models allow streaming of
raw CAN bus data via USB onto the PC in real-time. This can be set up in a machine-friendly interface
for easy software integration – but we also provide a user-friendly interface through
Wireshark, the #1 network analyzer. Simply connect your logger to the CAN bus
and then via USB to your PC and start! Wireshark provides a lot of awesome basic
functionality like filtering, color coding, graphical plots and a vast array of customization. But it’s our free Wireshark CAN bus plugin
that makes it really cool to work with. The plugin opens up a number of cool features,
incl. real-time conversion of OBD2 data and real-time conversion using a custom DBC database
– e.g. to stream human-readable J1939 data. Further, if you need to reverse engineer your
CAN bus application, we provide a helpful trace feature that lets you view all unique
IDs and analyze the patterns in the changing data. Perfect if you’re a car hacking enthusiast! To round it off, the plugin even allows you
to load a CAN logger CLX000 log file and manipulate it using all the above features within Wireshark. For deep dives on these features, check out
our GUIDES section on our website! Finally, we have our core Data Conversion
feature. This feature allows you to load your raw log
files and manage them in a number of ways. In particular, you can set up conversion rules
or load DBC databases and use these to scale your raw data into human readable form for
further analysis. Key options include log file merging and log
file down-sampling. For example, you can load 30 individual high-frequency
log files and in a few clicks get one single output file down-sampled into 5 minute frequency
data. You can even add summary statistics like maximum,
minimum and standard errors to the output. Finally, if you prefer working via other software,
we actually provide a built-in conversion tool that reformats our log files for use
in Vector’s CANalyzer software as well as PEAK’s software. That’s CANvas – for now! We continuously provide free software updates
based directly on user feedback through our online surveys. We are all about transparency and simplicity. That also means you can head over to
our Downloads section and check out our free CANvas software. Decide for yourself – we’re confident you’ll
love it! If you’ve got any questions, just contact
us – we aim to get back within 24 hours.
