Using the sigrok command-line ("sigrok-cli") to bulk process data derived from Tektronix oscilloscope data of 250 kbit/s CAN traffic on a real-world system (mobile cranes). The first sample data set is 5335 oscilloscope traces obtained with the trigger set to a negative pulse on CAN-H (to start off at the end of a CAN message) - corresponding to 6.5 recessive bits, 26 µsec (detecting the space in-between CAN messages). Sometimes there is a CAN message right after this, sometimes it is a bit delayed, and sometimes it is completely empty.
A sample command line (on Windows) is:
sigrok-cli -P can:bitrate=250000:can_rx="CAN RX" -P timing:data="CAN RX" -I csv:header=true:samplerate=5000000 -i "T:\stdHMF\UserData\scripts\Tektronix2PulseView\_PulseView_AllChannels_ACQ000001_Tektronix_f5000000.txt"

Using PulseView to decode data from a Tektronix oscilloscope of SPI communication to a CAN controller, MCP2515.
Interests
I am mostly interested in:
- The CAN protocol decoder (that page is currently empty, but it is listed on the protocol decoders page)
- CAN bus loggers, like IXXAT's (now acquired by HMS) USB-to-CAN compact/USB-to-CAN V2 and Kvaser's Memorator.
- The higher-level CANopen protocol (on top of CAN)
Protocol decoders
Non-empty wiki pages
Currently (2017-07-08), 28 of 77 protocol decoders (36%) have non-empty pages here on the wiki:
- ADNS5020
- AM230X
- ARM ETMV3
- ARM ITM
- ARM TPIU
- AUD

Shortcuts
- sigrok-cli man page
- Google+ group for sigrok
- PulseView. Includes the command line to get the source code using Git.
- PulseView, Windows binaries (nightly - development). Alternative location (but it seems redundant).
- Example data dumps - sample data in .sr format. Also includes instructions on how to contribute new ones. Includes the command line to get the whole thing using Git (as of 2017-11-26, 2286 "objects", 724 .sr files, about 65 MB in download size, 192 MB on disk).

- Protocol decoder HOWTO
- Protocol decoder API
- Supported protocol decoders
Building sigrok
- On Debian (e.g. Raspberry Pi): Installing required software
- On Debian (e.g. Raspberry Pi): Actual build
- Alternative to following the wiki pages: a script that will do most of it. ([sigrok-util.git] / cross-compile / linux / sigrok-cross-linux)
