Seems that this page has been removed. I'm using these libraries on an older project with LPC2368 which I'm trying to update, shame the pages are gone. :( Have they been archived anywhere?

    printf("setting up netif...\r\n");
    /* Set static IP address if required */
    IP4_ADDR(&netmask, 255,255,255,0);  // look at your router or type ipconfig on your PC for more info
    IP4_ADDR(&gateway, 192,168,0,1);      // this should be the IP address of your router
    IP4_ADDR(&ipaddr, 192,168,0,16);       // this is a static address you chose, the first 3 numbers should match your router, and the final number can be 2..255 but should be a number that's not already being used. e.g. setup the DHCP server on your router to start at 50, then use a fixed ip <50
    /* Initialise after configuration */
    lwip_init();
    netif->hwaddr_len = ETHARP_HWADDR_LEN;
    device_address((char *)netif->hwaddr);
    netif = netif_add(netif, &ipaddr, &netmask, &gateway, NULL, device_init, ip_input);
    netif->hostname = hostname;
    netif_set_default(netif);

    /* Start Network with static IP address */
    printf("Configuring device for STATIC IP ADDR...\r\n");
    netif_set_up(netif); 

    /* Start Network with DHCP */
//    printf("Configuring device for DHCP...\r\n");
//    dhcp_start(netif); // <-- Use DHCP

In case anyone else is looking - I was trying to find out to setup a static IP address instead of the DHCP with the ethernet tester software. [NOTE this is for the older LWIP libraries from a few years back; ignore this if you're using the latest supported mbed networking stack] Here's a code snippet with the answer: <<code>> printf("setting up netif...\r\n"); /* Set static IP address if required */ IP4_ADDR(&netmask, 255,255,255,0); // look at your router or type ipconfig on your PC for more info IP4_ADDR(&gateway, 192,168,0,1); // this should be the IP address of your router IP4_ADDR(&ipaddr, 192,168,0,16); // this is a static address you chose, the first 3 numbers should match your router, and the final number can be 2..255 but should be a number that's not already being used. e.g. setup the DHCP server on your router to start at 50, then use a fixed ip <50 /* Initialise after configuration */ lwip_init(); netif->hwaddr_len = ETHARP_HWADDR_LEN; device_address((char *)netif->hwaddr); netif = netif_add(netif, &ipaddr, &netmask, &gateway, NULL, device_init, ip_input); netif->hostname = hostname; netif_set_default(netif); /* Start Network with static IP address */ printf("Configuring device for STATIC IP ADDR...\r\n"); netif_set_up(netif); /* Start Network with DHCP */ // printf("Configuring device for DHCP...\r\n"); // dhcp_start(netif); // <-- Use DHCP <</code>>
