This will be a dramatic improvement over the current Lua based mapping which will cover 99% of the use cases. For unusual mapping requirements, you'll still be able to leverage on-board scripting.

Hi,

We have looked into importing dbc's; it could be good for the future. 

In our initial searching, we were not able to find a published spec for the file format. Do you know if such a spec exists or if it has been documented?

Brent,

the dbc it's just a text file, i usually open it with the vector Candb++, you will find in the demo version of Canalyzer  CANalyzer / CANoe 8.5 SP4 (64 bit)



If you take a look at the dbc, they are text file . I attached some example:

The empty file have this structure:

VERSION ""

 

 

NS_ :

                NS_DESC_

                CM_

                BA_DEF_

                BA_

                VAL_

                CAT_DEF_

                CAT_

                FILTER

                BA_DEF_DEF_

                EV_DATA_

                ENVVAR_DATA_

                SGTYPE_

                SGTYPE_VAL_

                BA_DEF_SGTYPE_

                BA_SGTYPE_

                SIG_TYPE_REF_

                VAL_TABLE_

                SIG_GROUP_

                SIG_VALTYPE_

                SIGTYPE_VALTYPE_

                BO_TX_BU_

                BA_DEF_REL_

                BA_REL_

                BA_DEF_DEF_REL_

                BU_SG_REL_

                BU_EV_REL_

                BU_BO_REL_

                SG_MUL_VAL_

 

BS_:

 

BU_:

 

 

 

BA_DEF_  "BusType" STRING ;

BA_DEF_DEF_  "BusType" "CAN";

If I add a message:

I will find:

BU_:

 

BO_ 291 New_Message_123: 8 Vector__XXX

 

Where BO_ identify a new message, after the space 291 is the decimal for the ID (0x123) , New_Message_123 is the name, 8 is the DLC

In case of ID extended (29 bit) you will find the decimal address as :

BO_ 2147483939 New_Message_123: 8 Vector__XXX

Where 2147483939 is the decimal for the HEX 80000123

 

 

If you add a comment to the message :

You will find in the dbc file:

CM_ BO_ 2147483939 "Comment_for_message_0x123";

Where CM_ is the comment and then the address

 

 

If I add a signal with no reference to a message:

BO_ 3221225472 VECTOR__INDEPENDENT_SIG_MSG: 0 Vector__XXX

 SG_ New_Signal_1 : 0|8@1- (1,0) [0|0] "" Vector__XXX

 

 

 

CM_ BO_ 3221225472 "This is a message for not used signals, created by Vector CANdb++ DBC OLE DB Provider.";

I think a script could be enough to import, i can try to help as much as i can, please let me know if have sense.

Regards and happy new year!

Fabrizio

Hi Brent
you can find DBC file description by Vector here:

http://www.haiwenku.com/view/658393.html

It would be good to create some interactive filter for choosing needed messages. Original DBC files from car manufactures contains description for more over thousands messages and it's not good idea to read them all.
