DE2_UDP example for download here free (feedbacks are wellcomed)

Hi all.

My goal is to get about 3Mbytes/sec data transfer rate from my DE2 board to PC.

Here in this example I get about 1.2 Mbytes/sec.

I'll accept comments about, how to speed up this, as well as suggests to improve the code, and some feedback from people that have interest in this theme. Could be in this thread or private.

You can download the full project from:

http://www.btxsistemas.com.ar/net2.zip

I've used Quartus II 7.2 full suite. And the Wireshark software (http://www.wireshark.org/) like a net sniffer, but also, I've included in the main project folder, a UDP reciever to test the comunication between the DE2 board and the PC, if you wont to download the wireshark.

Don't forget to specify your IP address and your MAC address in the NIOS hello_word "C" code to get it work properly.

The main project is a modification of the DE2_NET demostration code that comes with the DE2 board.

Have fun, and I'll be waiting for some comments.

    Hi.

    You can specify a MAC address and a IP simply, write them in the correct place of the code....do you take a look at it ??

    Wireshark is a net sniffer...just download it, and read the help file, it is very easy to understand.

    Cheers

    Hi.

    You have in the NIOS code: 

    
IPsource_1 = 0xC0;        // Assign ie: 192.168.0.44 IP for the DE2 
 IPsource_2 = 0xA8;
 IPsource_3 = 0x00;
 IPsource_4 = 0x2C;
 IPdestination_1 = 0xxx;   // Insert your IP data here
 IPdestination_2 = 0xxx;
 IPdestination_3 = 0xxx;
 IPdestination_4 = 0xxx;
 Mac_dest1 = 0xxx;         // Insert your MAC address data here
 Mac_dest2 = 0xxx;
 Mac_dest3 = 0xxx;
 Mac_dest4 = 0xxx;
 Mac_dest5 = 0xxx;
 Mac_dest6 = 0xxx;
 Mac_source1 =  0x01;      // Assign an MAC address for DE2
 Mac_source2 =  0x60;
 Mac_source3 =  0x6E;
 Mac_source4 =  0x11;
 Mac_source5 =  0x02;
 Mac_source6 =  0x0F;
    Well, look for in your OS "net conections" (If it's XP) and see the details for the active one.

    You'll be find there your machine IP and your MAC address, write them in IPdestination and Mac_dest respectively. No more to do.

    The NIOS code has asigned an IP for your DE2 and a Mac too, you can change it if you want for another, So your DE2 will have for ever you run that code the same IP and MAC, change the IPdest and Macdest if you run the code in another computer.....or READ some more about net connections.

    Cheers.

    Alberto.

    Dear BTXSistemas , The program is full work, but I wonder if you use MATLAB to receive data, because i've tried, but I can't get the data.

    Hello!

    Thanks for a project, but an archive seems to be broken. Could you repack it and upload somewhere else? I'd be very grateful.

    The file was compressed using Winzip, I've tested it, and it is fine.
