It's a bit confusing that the DBC CAN ID shown at 2:33 is not used when showing the DBC file at 2:38 (its a bit more of a problem when following along on the website).
What exactly is the difference between EDS and DBC? Is it possible (ex. not against terms-of-service) to convert a log file captured in linux (candump) or Peak's PCAN (.trc) and convert it to the CanEdge mf4/mdf4 format, so that it can be used with CSS's visualization tools (asammdf GUI, python/matlab api, etc)? Or perhaps other reasons why writing a converter that outputs mf4 is not possible or extremely difficult? If using CSS is not recommended, any suggestions for an open-source canopen visualization software (ex. PlotJuggler with the DataStreamCAN plugin)? I'm mostly interested in creating a dbc file for a canopen device (gcan-4128), and plot the data real-time, and occasionally send it control commands (SDO Write).
The start bit is 24, meaning that you'd start the signal extraction from this bit (i.e. after the 3rd byte). One byte is 8 bits, so with a bit length of 16 bits it means you need to extract 2 bytes - which is what is shown in the video. The byte ordering is then the reason why the order of the bytes is reversed. Hope clear.
I know, very late reply: One HEX-digit = 1 Nibble = 4 Bit, 0-F in Hex or 0-15 in decimal (not 8 Bit as I also have confused in the past sometimes). So 0x68 = 1 Byte, 0x13 = 1 Byte
@@CSSElectronics-CAN-Logger-X000 where can we find DBC files? Are DBC files are common among constructors? can a single file be used for multiple cars or boards? Is it possible to use it for generic CAN card like those we find with Arduino, STM32, Amtel or Raspberry PIs?
I have a question! how do we understand the DBC file correctly? and can we build a DBC file from an ARXML file? I am working on an issue where I am defining a GenSIgStartValue as BA_DEF_ SG_ INT X Y; but when I am adding the default value for it as BA_DEF_DEF_ "GenSigStartValue" 0; I am getting an error while opening in vector tool. any help would greatly be appreciated
I suggest checking out our CAN DBC file intro in the Guides section of our website. The specific question you have is probably a bit more niche though, I'd recommend trying to build that DBC via Vector's CANDB++ editor in this case

Very informative about DBC files

where can you find dose DBCs?
I am looking for one for Renault Megane 2 and one for Dacia Duster 2016. Does anyone found them?
Thanks in advance!
Very good!
Very usefull site, helped a lot!
Thanks Roy

In part 2:54. start bis 24, and bit length is 16 (means 8 + 8 bits) = means till 68. So why they cover data length of 6813 (which is 32?)

Great Content
Thanks!
How this CAN frames (29 bit identifier/ 11 bit identifiers ) linked to these DBC files?
We suggest checking out our intro article and our DBC editor playground to understand the logic

I have a question!
how do we understand the DBC file correctly? and can we build a DBC file from an ARXML file?
