# Usage with Linux
First of all, you need the `can-utils` package
```
$ sudo apt install can-utils
```
Then, use the commands below to start the slcan daemon
```
sudo slcand -S 115200 -s 6 -o /dev/ttyUSB0 can0
```
- `-S` : Serial baud rate. Put the same value as `SERIAL_SPEED`
- `-s` : CAN speed. Check the [Lawicel documentation](https://www.canusb.com/docs/can232_v3.pdf) to choose the speed you want
- `-o` : Send an Open command (explained in Lawicel documentation)
- `/dev/ttyUSB0` : Your Arduino serial port
- `can0` : The name you want for your SocketCAN interface
Finally, bring the interface up
```
$ sudo ip link set can0 up
```
You can now use your preferred tools to manipulate the CAN ! (candump, SavvyCAN...)
## SLCAN (Lawicel) Implementation ## SLCAN (Lawicel) Implementation
SLGreen implements the SLCAN (Lawicel) protocol to allow interactive communication with the CAN bus via a serial port.
