For this code I used the src from pd. This lines are written in c and they create, communicate and write info to a socket. I added a ';' at the end of the string that is generated from the interaction with the keyboard. That allows to send the info to pd. the patch with netreceive has to be open in pd otherwise the socket won't be created. It was written in fc3.

#define BUFSIZE 4096

int main(int argc, char **argv)

{

    int sockfd, portno=3000, protocol;

    struct sockaddr_in server;

    struct hostent *hp;

    char *hostname;

    hostname = "127.0.0.1";

    protocol = SOCK_STREAM;

    sockfd = socket(AF_INET, protocol, 0);

    if (sockfd < 0) exit(1);

    server.sin_family = AF_INET;//connect socket using hostname 

    hp = gethostbyname(hostname);

    if (hp == 0) exit(1);

    memcpy((char *)&server.sin_addr, (char *)hp->h_addr, hp->h_length);

    server.sin_port = htons((unsigned short)portno); //assign client port number

    connect(sockfd,(struct sockaddr *) &server, sizeof (server));//connect    

    while (1) //now loop reading stdin and sending  it to socket

      {

    char buf[BUFSIZE], *bp, nsent, nsend;

    fgets(buf, BUFSIZE, stdin);

        nsend = strlen(buf);

        for (bp = buf, nsent = 0; nsent < nsend;)

      {

        int res = send(sockfd, buf, nsend-nsent, 0);

        if (res < 0) exit(1);

        send(sockfd, ";", 1, 0);

        nsent += res;

        bp += res;

      }

How can I find out what midiindev I have to use?

Thank you a lot.

I'm guessing your patch receives the 256 values in a list?

You can extract the Nth element from a list with a message box like [ $N (

But for a list length 256 this could get tedious to patch. What I suggest is making a Java program to make the patch.

Make a patch to extract the right parts from the list for a short list, say length 4, perhaps with a [ t l l l l] connected up to [ $N M (, where M=N-1, each connected to [ unpack f f ( ==> [ tabwrite ] . If you create the message boxes last, it will be easier to write the program.

Then write a Java program to generate the patch you want. It's best if the patch generated is a complete abstraction, so you don't have to edit the output patch each time you edit the Java program (say if you want different length lists).

Here is an example of a Java program that I wrote to generate a patch with 256 number boxes in a 4x64 grid. It doesn't follow my guidelines for being a complete abstraction - I edited the patch afterwards to add more stuff, which will cause me problems next time I want a different sized grid....

I used the netserver and netclient from pd to create a cliente server that reads data from java into pd but I am not able to see inside pd objects and numbers boxes the values that java produces. I think the problem isn´t with java but with pd.

I use maxlib in java to get the values and send to pd with out.println(R_[]) but i can´t see them in pd where I need to work with.

Anybody can help me?

Thanx_
