broadcast enable

[ljmarkus]

Hello,

how can i enable the broadcast revice by the enc28j60 ?

Spi_Ethernet_Init(PORTB, 0, PORTB, 1, myMacAddr, myIpAddr, Spi_Ethernet_FULLDUPLEX) ;

and then ?

why: i must recive UDP Data from BC.

in the function Spi_Ethernet_UserUDP(var remoteHost : array[4] of byte;
remotePort, destPort, reqLength : word) : word;

i can not see data to revice per BC, but i can see recive Data for my ip.


Thanks, Markus

Hello.

None of an idea?

Hi,
You'll have to be a little bit clearer on this.

Hello,

- What do you mean by broadcast revice?

why: i must recive UDP Data from BC.

in the function Spi_Ethernet_UserUDP(var remoteHost : array[4] of byte;
remotePort, destPort, reqLength : word) : word;

i can not see data to revice per BC, but i can see recive Data for my ip.

- What do you mean by BC? UDP packets go through IP protocl, so I do not understand your question.

Hello,

Code: Select all

  myIpAddr[0] := 2;        // 2.27.27.50
  myIpAddr[1] := 27;
  myIpAddr[2] := 27;
  myIpAddr[3] := 50;

  Spi_Ethernet_Init(PORTB, 0, PORTB, 1, myMacAddr, myIpAddr, Spi_Ethernet_FULLDUPLEX) ;


 while true do                 // do forever
    begin
      Spi_Ethernet_doPacket() ;     // process incoming Ethernet packets
      {*
       * add your stuff here if needed
       * ENC28J60_doPacket() must be called as often as possible
       * otherwise packets could be lost
       *}
    end;

The Ip for my ENC is 2.27.27.50 and i must revice a poll packet at 2.255.255.255.

Well,
Enc and your PC have to me on the same subnet in order to communicate. Check you subnet mask settings and assign to ENC appropriate IP address corresponding the mask settings.
i.e.
if your PC address is 2.27.27.1 and your subnet mask is 255.255.255.0, an IP address from the 2.27.27.x pool of addresses must be assigned to enc.

Hello,

my Network is:
(ArtNet spec.) Subnet must be 255.0.0.0


PC1 : IP 2.27.27.10 - Subnet 255.0.0.0
Console : IP 2.27.27.12 - Subnet 255.0.0.0

Ethernet Interface with ENC : IP 2.27.27.50

PC1 and Console make a Request poll to 2.255.255.255 and the Interface must answer to the sender eg. Console.

Ok, I see what you want to do here. However, current library does not support broadcast requests. You'll could change your PC application to send poll requests to enc address.
Also, I'm just wondering: Usually, broadcasts are done with 255.255.255.255 IP address, so even with the broadcast support, the library would not answer to 2.255.255.255.

Hello,

hmm,

poll request is only possible to 2.255.255.255.

I am also interested in broadcast recieve and send!
