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. If you are intrested in the package and have the hardware, feel free to contact me and we will get it on the way.
• 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.
