CANvas is our 100% free supporting software tool for the CLX000 series of CAN bus data loggers.

For a quick intro, check out our 4 minute video above!

CANvas provides a full suite of powerful features - below you can learn more about configuration, live streaming and conversion.

For further deep-dive articles on key features, check out our GUIDES section!


The 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!


  • Logger ID, data separator, file split limit (e.g. new log every 100 MB)
  • Bit rate incl. optional auto-detection and Silent/'Listen Only' mode
  • Customizable RTC and date/timestamp format (CL2000/3000)
  • Cyclic Logging: Delete oldest files when SD card is full
  • Heartbeat Signal: Receive status message every second from the logger
  • Control Signal: Optionally use custom trigger CAN ID to turn logging on/off
  • Transmit: Add custom CAN messages to be sent periodically (e.g. for OBD2)
  • Filtering: Specify message filters & down-sampling to focus your logging
  • NEW: For the CL3000, you can also easily configure the WiFi settings
  • NEW: Easily log OBD2 parameters with the built-in database
  • NEW: Enable WiFi TimeSync to keep your CL3000 RTCs in sync
  • NEW: Split log files based on time (time of day or period)
  • NEW: Virtually cap the size of the logger's SD card


As a new feature, the CLX000 is no longer “just” a data logger. It now also serves as a fully functional CAN interface - which means you can live stream CAN bus data directly on your PC. With CANvas, it takes just 2 clicks to start streaming! 

We decided early on not build a custom GUI from scratch for the live stream. Instead, we power it via the World’s most popular network analyzer, Wireshark. But it doesn’t end there: We also designed a free, open source & powerful plugin for Wireshark to infuse a number of critical CAN bus features.


  • Advanced and highly customizable message/data filtering
  • Plugin DBC support to stream human-readable data (aka engineering values)
  • Plugin OBD2 dissector, allowing you to convert all standard parameters
  • Plugin ‘Live View’ (trace), showing a fixed view of unique CAN IDs and highlighting all changes to data bytes - powerful for CAN sniffing/hacking
  • Intuitive real-time graphical plots of converted data (e.g. OBD2, J1939, …)
  • Easily export to multiple formats incl. *.csv, *.c, *.txt and more
  • Load a CLX000 log file to leverage the Wireshark & Plugin features
  • Connect to the logger while data logging and leverage all the above

 … and much more!

If you’re interested, check out our GUIDES page for several articles on the Live Stream features - incl. OBD2 dissector, DBC conversion, CAN Live IDs and more.


Finally, CANvas supports easy conversion of your CLX000 log files!

Simply load a DBC file, browse to your log files and convert the data to scaled engineering values. The output format is *.csv, ready for import into e.g. Excel or other 3rd party software.


Together, these tools & features make the CLX000 incredibly versatile - and a fantastic value-for-money logger. CANvas is 100% free and we’ll keep it that way. Despite this, we constantly upgrade and improve the software - and we would love your ideas! Please spend 2 minutes on the below feature survey. Your opinion is the #1 driver of our roadmap prioritization!
