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

in Artila CD for the SocketCAN API.

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

Configure CAN:

To configure CAN device, you can use utility programs:

/canconfig

/candump

/canecho

/cansend

/cansequnce

User can also use ip command to configure CAN e.g.

/ip link set can0 down

/ip link set can0 type can bitrate 250000

/ip link set can0 up

/ip –details link show can0

The boot up CAN bit rate setting is at /etc/can_config

Format: [can port]: [bit rate]

0:250000

1:250000

Bit rate: 10K~ 1M
