HOW TO INTERFACE BETWEEN ETHERNET(CYCLONE III) AND PCs(Labtop)

i don't understand. Can you discrible your mind. I need to instruction detail about it. example .... I'm confuse... worried!!!!!

help me !!! anyone

Yes I do.

I'm doing on Development Board on Cyclone III. But I don't know how to set up IP for Cyclone III's Ethernet. My task is when I ping "Ethernet's IP address" it answer "Relay ...."comment ????????

that's all!!!

You need to upload the nios standard image (delivered with the kit) and compile and run a web server example..

Then the board will try to configure itself through dhcp so it can be a good idea to have a dhcp server on your PC if you don't want to configure the IP manually in the source code.

I can set up IP address for Cyclone III's Ethernet, and this is my code when I declare for this code.

or i can set up other.

# define IP4_ADDR(ipaddr, a,b,c,d) ipaddr =

htonl((((alt_u32)(a & 0xff) << 24) | ((alt_u32)(b & 0xff) << 16) |

((alt_u32)(c & 0xff) << 8) | (alt_u32)(d & 0xff)))

mus i can do now?

i'm confuse.

What does it say when you run the web server example?

In the project you should have a file with two functions that are called by the IP stack to set up the MAC and IP addresses.

okey.but i cannot...

i write a code for set up IP addresss.

it cannot run.

How must i declare for this code?

that's :

Ip address?

example: i want to declare??????

i need a code for this. :confused::confused::(:(

What you posted are definitions, not code that actually set up the address.

What software project did you use? Have a look at the network_utilities.c file, there is a function called get_ip_addr(). The actual IP address to use is declared in a header file (web_server.h for the web server example).
