# Slcanuino

This is an Arduino sketch which makes a CAN-BUS shield into a CAN-USB adapter for Linux SocketCAN(can-utils). Library files under Canbus folder originaly comes from 'CAN-BUS ECU Reader demo sketch v4' on skpang and were modified. The files should be copied under ~/Arduino/libraries/ to compile the sketch file:'slcan.ino'.

# Supported hardware

I tested this sketch on the following 'CAN-BUS Shield'.

https://www.sparkfun.com/products/10039

If you are using SeeedStudio's one with its default setting please modify MCP2515_CS 'B,2' with 'B,1' in 'Canbus/defaults.h'.

# How to use

Burn your Arduino with this and install can-utils for your linux environment in advance.

## Deps

1. slcan (kernel module)

2. SocketCAN (http://www.pengutronix.de/software/libsocketcan/)

3. can-utils (https://github.com/linux-can/can-utils)

or just install can-utils package.

    $ sudo apt install can-utils

## Setup

Please replace ttyUSB with ttyACM in case of using Arduino Uno.

    $ sudo slcan_attach -f -s6 -o /dev/ttyUSB0  

    $ sudo slcand -S 1000000 ttyUSB0 can0  

    $ sudo ifconfig can0 up  

then,

    $ candump can0

## Cleanup

    $ sudo ifconfig can0 down  

    $ sudo killall slcand
