Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial
|
|
|
|
|
communications protocol which was developed by Bosch in
|
|
|
|
|
1991, mainly for automotive, but now widely used in marine
|
|
|
|
|
(NMEA2000), industrial, and medical applications.
|
|
|
|
|
More information on the CAN network protocol family PF_CAN
|
|
|
|
|
is contained in <Documentation/networking/can.txt>.

If you want CAN support you should say Y here and also to the
|
|
|
|
|
specific driver for your controller(s) below.

The raw CAN protocol option offers access to the CAN bus via
|
|
|
|
|
the BSD socket API. You probably want to use the raw socket in
|
|
|
|
|
most cases where no higher level protocol is being used. The raw
|
|
|
|
|
socket has several filter options e.g. ID masking / error frames.
|
|
|
|
|
To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.
