==== Setting CAN bautrate ====
<code>
root@MBaXXX:~ canconfig can<interface nr> bitrate <baudrate>
</code>
++++ example |
<code>
root@MBAXXX:~ canconfig can0 bitrate 500000
</code>
++++
==== Activate CAN Interface ====
<code>
root@MBaXXX:~ ifconfig can<interface nr> up
</code>
++++ example |
<code>
root@MBaXXX:~ ifconfig can0 up
</code>
