can_dbc_parser 1.1.0

CAN DBC parser for dart. Load the DBC from bytes and use the package to decode, encode CAN signals

Dart CAN DBC Parser

The package helps to parse the CAN DBC file.

Features

DBC parsing, CAN decoding, CAN encoding

Usage

You can upload the file using file_picker to application and create bytes from the file selected

FilePickerResult? result = await FilePicker.platform.pickFiles();
Uint8List bytes = result.files.first.bytes as Uint8List;
DBCDatabase can = await DBCDatabase.loadFromBytes(bytes);

When the signals are loaded, by default the min value is assigned to the signal.

To decode the CAN Message use

DBCDatabase can = await DBCDatabase.loadFromBytes(bytes);

Uint8List messageBytes = Uint8List(10);
messageBytes.buffer.asByteData().setUint16(0, 849);
messageBytes.buffer.asByteData().setUint16(2, 0xFFFF);
messageBytes.buffer.asByteData().setUint16(4, 0xFFFF);
messageBytes.buffer.asByteData().setUint16(6, 0xFFFF);
messageBytes.buffer.asByteData().setUint16(8, 0xFFFF);
Map<String, num> decoded = can.decode(messageBytes);

To encode the CAN Message, update the signal value and use encodeMessage(canID). Currently, it does not support for Multiplexed signals.

can.can.database[849]?[signal_name]?.value = new_signal_value;
Uint8List encoded = can.encodeMessage(849);

Get the map of values for a particular signal.

// Signal: Switch_State 1 "ON" 0 "OFF" 
Map<int, String> valueMap = can.valueTable["Switch_State"]
// Results in { 0 : "OFF" , 1 : "ON" }
