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

[Altera_Forum]

Hi everybody!!! 

 I'm studying with a topics "Interface between Ethernet of Cyclone III and computer(PC or labtop)" It's means that I must "ping IP and Relay from Cyclone's Ethernet".   I don't know how to practice that i use Verilog language.  it's difficult to me!!!  Help me everybody

[Altera_Forum]

Take Cyclone III Development kit or NEEK web server examples for starters.

[Altera_Forum]

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

 help me !!! anyone

[Altera_Forum]

What development kit do you have? Isn't it shipped with design examples?

[Altera_Forum]

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!!!

[Altera_Forum]

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.

[Altera_Forum]

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.

[Altera_Forum]

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::(:(

[Altera_Forum]

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).

[Altera_Forum]

What's up? 

 I'm looking forward to receiving any the question.  And In the meantime, I tried to review this problem. But there're so numerous for my doing.  In summary, The most of different to me that's I cannot define IP address on DEVELOPMENT KIT(CYCLONE III).   I wish that anybody will help me!!  thanks for your helping.

[Altera_Forum]

Did you read my last answer?

[Altera_Forum]

Yes, I did. and Here this code I found.  

 * get_ip_addr()  *   * This routine is called by InterNiche to obtain an IP address for the  * specified network adapter. Like the MAC address, obtaining an IP address is  * very system-dependant and therefore this function is exported for the  * developer to control.  *   * In our system, we are either attempting DHCP auto-negotiation of IP address,  * or we are setting our own static IP, Gateway, and Subnet Mask addresses our  * self. This routine is where that happens.  */ int get_ip_addr(alt_iniche_dev *p_dev,  ip_addr* ipaddr,  ip_addr* netmask,  ip_addr* gw,  int* use_dhcp) {   IP4_ADDR(*ipaddr, IPADDR0, IPADDR1, IPADDR2, IPADDR3);  IP4_ADDR(*gw, GWADDR0, GWADDR1, GWADDR2, GWADDR3);  IP4_ADDR(*netmask, MSKADDR0, MSKADDR1, MSKADDR2, MSKADDR3);  # ifdef DHCP_CLIENT  *use_dhcp = 1; # else /* not DHCP_CLIENT */  *use_dhcp = 0;   printf("Static IP Address is %d.%d.%d.%d\n",  ip4_addr1(*ipaddr),  ip4_addr2(*ipaddr),  ip4_addr3(*ipaddr),  ip4_addr4(*ipaddr)); # endif /* not DHCP_CLIENT */   /* Non-standard API: return 1 for success */  return 1; }   So, Dynamic IP or static IP? And I'm really understand clearly how to create code from this program.

[Altera_Forum]

It depends on define. 

 Use# undef DHCP_CLIENT in the beginning of the file for static IP or# define DHCP_CLIENT for DHCP.

[Altera_Forum]

those defines are in a header file, just as I said in my post on top of this page. You can enable or disable DHCP with the DHCP_CLIENT definition, and if you want a static IP, change the defines for IPADDR0..3 in that same header file.

[Altera_Forum]

Daixiwen! 

 I had done! I use DHCP for this problem. But How to know IP_address, Mean that, I want to ping "IP_address" from computer on Terminal window and then at the moment the signal relay and display on the Terminal Terminal?  How ?

[Altera_Forum]

The Interniche stack says in the console what IP address it is using. Just ping that one.

[Altera_Forum]

How to ping? You talk too general. I cannot be images!? more clearly? about ping IP?

[Altera_Forum]

I don't understand what you are saying... You just said you wanted to ping the card from a terminal window. Don't you know how to do that? 

The embedded application will say its IP address in the console. You can just recopy it when you type the ping command in the terminal.

[Altera_Forum]

Of course, That's I want to interface between on Board(Development kit) Cyclone III's Ethernet and a the other computer via Cable. And To solve this problem. I must have programmed to create a IP address and then from a computer(is connected with Ethernet via the cable). Then, I open the Terminal(DOS). typing "cmd" command and then "ping" IP_address(this address had programmed) and if the system rely ....... and display on the terminal is ok????????????????????????? 

  Thanks for your many helping:(
