3.28 SocketCAN
Matrix-522 supports SocketCAN which implements a standard network interface for CAN protocols for
Linux. Unlike other CAN implementation for Linux based on character devices, SocketCAN uses
Berkeley socket API, the Linux network stack and implements CAN device drivers as network
interfaces.
The CAN socket API has been designed as similar as possible to the TCP/IP protocols to allow
programmers, familiar with network programming, to easily learn how to use CAN sockets.
Please refer to the document:
\Example\CanBus\socketcan\socketCAN.txt on Artila FTP for the SocketCAN API.
3.29 libsocketcan
The libsocketcan library allows you to control some basic functions in socketcan from userspace.
Please refer to:
\Example\CanBus\libsocketcan for the examples program for libsocketcan.

4. Artila Utility Software
The introduction of Artila utility software as follow:
4.1 update
Update loader, environment file and kernel image. Type update--help to find the command usage.
Update can only operate under supervisor mode (password: root). Please use command su and login
as root.
4.2 setuart
Configure serial port setting. An example show as followed to configure port 1 as RS-485 interface
with baud rate 921600.
4.3 setconsole
Unlike Matrix-510 which shares the serial console port with the serial port 3, Matrix-522 uses dedicated
pins for serial console (debug port). setconsole command allows user to redirect the serial console
port to any one of the four serial port of Matrix-522. Therefore user can avoid opening the metal case
to access the serial console.
