CANvas - Configure, Stream & Decode CAN Bus Data

Need to easily configure your CLX000 - or stream/process data?

CANvas is a 100% free optional software for the CLX000 CAN bus data loggers.

In this intro, we outline key features for configuration, streaming and data processing.

Note: For logging data to an SD we now recommend the CANedge - and for streaming via USB/Ethernet we recommend the CANsub interface.

Configure your CAN logger

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!

Key features

• General: Logger ID, separators, file/time split limit (e.g. new log every 50 MB)
• Bit rate incl. optional auto-detection and Silent/'Listen Only' mode
• RTC: Customizable RTC and date/timestamp format (CL2000/3000)
• Cyclic Logging: Delete oldest files when SD card is full
• Heartbeat: Receive status message every second from the logger
• Control: 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
• WiFi: For the CL3000, you can easily configure the WiFi settings
• OBD2 DB: Easily log OBD2 parameters with the built-in database
• WiFi TimeSync: Keep your CL3000 RTCs in sync via online clock
• Virtual SD cap: Set a virtual max size on the logger's SD card

Live stream CAN bus data

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!

Via CANvas, you can stream data through the World's most popular network analyzer, Wireshark. Further, our free open source plugin for Wireshark adds a number of critical CAN bus features.

Key features

• Advanced and highly customizable message/data filtering
• DBC support: Stream human-readable data (aka engineering values)
• OBD2 dissector: Convert all Mode 01 standard parameters in real-time
• 'CAN Live': Trace unique CAN IDs and colorize data changes (for CAN sniffing)
• Plots: 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 features

Process & DBC-convert logged data

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

Simply load a DBC file, 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.

Key features

• Load DBC files: Convert via the standard DBC format (incl. J1939)
• FMS: Built-in support for FMS conversion rules (buses, trucks)
• Batch convert: Load batches of log files & link them based on session IDs
• Rules: Add custom conversion rules (incl. name, start bit, length, scale, offset)
• Downsampling: Downsample the logged data to e.g. 5 min interval output
• Columns: Add custom columns to the output file
• Timestamps: Adjust timestamps to e.g. be split in columns (Excel pivot friendly)
• Merge log files: Merge multiple files into one output file
• Re-format log files: Change format into Vector CANalyzer or PEAK formats
• Summary Stats: Add summary statistics to downsampled data (std. dev., min, max)
• OBD2: Easily convert OBD2 data with built-in conversion rules
• Auto-convert: Set up scheduled auto conversion in seconds
