This example shows using the SeeedStudio arch pro as an Ethernet server. It will initialize the Ethernet port, display its IP address, display the IP address of connecting clients and then return data sent from the client.

Dependencies:   EthernetInterface SeeedGrayOLED USBDevice mbed-rtos mbed

Fork of Ethernet_Status_HelloWorld by Edoardo De Marchi

This mbed server example for SeeedStudio also needs a client to connect.

I compiled and ran this on my opensuse linux virtual machine but I think it should compile and run fine on most linux distrubutions and probably on OSX as well:

<codei>

  1. include <stdio.h>
  2. include <stdlib.h>
  3. include <unistd.h>
  4. include <string.h>
  5. include <sys/types.h>
  6. include <sys/socket.h>
  7. include <netinet/in.h>
  8. include <netdb.h>

void error(const char *msg) { perror(msg); exit(0); }

int main(int argc, char *argv[]) { int sockfd, portno, n; struct sockaddr_in serv_addr; struct hostent *server;

char buffer[256]; if (argc < 3) { fprintf(stderr,"usage %s hostname port\n", argv[0]); exit(0); } portno = atoi(argv[2]); sockfd = socket(AF_INET, SOCK_STREAM, 0); if (sockfd < 0) error("ERROR opening socket"); server = gethostbyname(argv[1]); if (server == NULL) { fprintf(stderr,"ERROR, no such host\n"); exit(0); } bzero((char *) &serv_addr, sizeof(serv_addr)); serv_addr.sin_family = AF_INET; bcopy((char *)server->h_addr, (char *)&serv_addr.sin_addr.s_addr, server->h_length); serv_addr.sin_port = htons(portno); if (connect(sockfd,(struct sockaddr *) &serv_addr,sizeof(serv_addr)) < 0) error("ERROR connecting"); printf("Please enter the message: "); bzero(buffer,256); fgets(buffer,255,stdin); n = write(sockfd,buffer,strlen(buffer)); if (n < 0) error("ERROR writing to socket"); bzero(buffer,256); n = read(sockfd,buffer,255); if (n < 0) error("ERROR reading from socket"); printf("%s\n",buffer); close(sockfd); return 0; } <code>
