Probably the first .NET DBC file parser. Includes packing and unpacking functionality for sending and receiving CAN signals.

Below is a quick preview of the extracted data using a Tesla dbc file taken from commaai/opendbc project:



Install the library via Nuget Packages and add at the top of your file:

using DbcParserLib;

Then to parse a dbc file use:

DbcParser dbc = new DbcParser();

Access the nodes, messages and signals using:


Packing/Unpacking signals

Example for packing/unpacking a signal: 14 bits, Min: -61.92, Max: 101.91

Signal sig = new Signal();
sig.Length = 14;
sig.StartBit = 2;
sig.IsSigned = 1;
sig.ByteOrder = 1; // 0 = Big Endian (Motorola), 1 = Little Endian (Intel)
sig.Factor = 0.01;
sig.Offset = 20;
ulong TxMsg = dbc.TxSignalPack(-34.3, sig);
double val = dbc.RxSignalUnpack(TxMsg, sig);

Multiple signals can be packed before CAN transmission using:

ulong TxMsg = 0;
TxMsg |= dbc.TxSignalPack(value1, sig1);
TxMsg |= dbc.TxSignalPack(value2, sig2);
TxMsg |= dbc.TxSignalPack(value3, sig3);
// ...
// Send TxMsg on CAN

The user needs to make sure that the signals do not overlap with each other by properly specifying the Length and StartBit.
