In the CDC Ethernet over USB code there appears to be an IP address in the code, why?

Question asked by rick stuart on Nov 28, 2014

Hi,

 

I'm thinking along the lines that the CDC Ethernet over USB (cdc_vnic_twrk70f120m) code should only pass traffic from USB to Ethernet and back and have no need for an IP address.  But in the file "virtuial_nic_enet.h" there appears to be an IP address:

 

On Line 65 (or there abouts):

    #define ENET_IPADDR  IPADDR(169,254,3,3)/* Default IP Address */

 

Does this serve a purpose?  Perhaps if I understand this I could better understand how the Freescale example works.

 

-thanks
