CAN interfaces¶

Setup and testing the CAN interfaces with Linux¶

The TI wiki site has some good information on getting the linux CAN utilities built for the 335X
see http://processors.wiki.ti.com/index.php/DCAN_Driver_Guide

Once you have the CAN utilities built and installed on the target, can use the following commands
from http://support.criticallink.com/redmine//projects/indio/wiki/CAN_support to test the interface.

root@mityarm335x-dev:~# ip link set can0 type can bitrate <your-desired-bitrate-in-hz> triple-sampling on
root@mityarm335x-dev:~# ifconfig can0 up
root@mityarm335x-dev:~# cansend can0 -i 0x10 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88

Common bit-rates¶

10 kBaud = 10000
20 kBaud = 20000
50 kBaud = 50000
100 kBaud = 100000
125 kBaud = 125000
250 kBaud = 250000
500 kBaud = 500000
800 kBaud = 800000
1 MBaud = 1000000
