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'.

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

$ sudo slcand -S 1000000 ttyUSB0 can0  
$ sudo ifconfig can0 up  

then,

$ candump can0

cleanup:

$ sudo ifconfig can0 down  
$ sudo killall slcand
