Linux CAN

Dart implementation of SocketCAN.

Big shout out to @ardera who helped me a lot developing this package.

Using the package

There are no system dependenices needed, except the libc.so.6 which probably should be installed on your device.

Setup

At first create a CanDevice. You can set a custom bitrate, default is 500 000. Afterwards call setup(). A SocketException will be thrown if something goes wrong.

final canDevice = CanDevice(bitrate: 250000);
await canDevice.setup();

Communication

To receive data use read(), which returns a CanFrame. It contains the id and data of the frame.

final frame = canDevice.read();
print("Frame id: ${frame.id}");
print("Frame data: ${frame.data}");

To close the socket use close().

Limitations

• Because I have no hardware which allows writing CAN data, only reading is supported at the moment.
• For now only can0 is supported as an interface.
• You can not change the bitrate once it is set. To change the bitrate a reboot of your device is currently needed.
