can_dbc_parser 1.0.0

CAN DBC parser for dart

Dart DBC Parser for web

The package helps to parse the CAN DBC file for web.

Features

DBC parsing, CAN decoding

Usage

Web natively doesn't support File (dart:io is not supported in Web). You can make use of this package to create CAN Database and decode CAN messages.

You can upload the file using file_picker to web 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);
