hello forum I am new to TCP/IP anybody who used uIP before can answer my question ? this above is main body if uIP how must I modify this code so that it doesnot act as a webserver but receives and sends back 200 or 300 bytes of data ? thank you #3rd-party #uip #uip #lwip

Hi ,

I want to know if you've found a solution for your probleme cuz i have the same problem. I want to ask u also about smthing, i've download Adam dunkel stack uIP and i have a serious problem, i used the simple application named '' hello world'' in apps directory and the uip_len always return 0 int main(void) {     int i;     uip_ipaddr_t ipaddr;     struct timer periodic_timer;     //struct uip_conn* conn;     clock_init();     // Clock second =1000     timer_set(&periodic_timer, CLOCK_SECOND / 2);     // Initialize the ethernet device driver     network_init();     //Initialize the uIP TCP/IP stack     uip_init();     //Init WEB server     uip_ipaddr(ipaddr, 192,168,1,1);     uip_sethostaddr(ipaddr);     //     //    uip_ipaddr(ipaddr, 192,168,1,2);     //    uip_setdraddr(ipaddr);     //     //    uip_ipaddr(ipaddr, 255,255,255,0);     //    uip_setnetmask(ipaddr);     hello_world_init();     /* 4 test purpose     conn=uip_connect((192,168,2,1), 1000);     if(conn==0){         uip_abort();         return;     }*/     while(1) {         uip_len = network_read();         if(uip_len > 0) {             uip_input();             /* If the above function invocation resulted in data that          should be sent out on the network, the global variable          uip_len is set to a value > 0. */             if(uip_len > 0) {                 network_send();             }         } else if(timer_expired(&periodic_timer)) {             timer_reset(&periodic_timer);             for(i = 0; i < UIP_CONNS; i++) {                 uip_periodic(i);                 /* If the above function invocation resulted in data that            should be sent out on the network, the global variable            uip_len is set to a value > 0. */                 if(uip_len > 0) {    /* problem here */                     network_send();                 }             } #if UIP_UDP             for(i = 0; i < UIP_UDP_CONNS; i++) {                 uip_udp_periodic(i);                 /* If the above function invocation resulted in data that            should be sent out on the network, the global variable            uip_len is set to a value > 0. */                 if(uip_len > 0) {                     network_send();                 }             } #endif /* UIP_UDP */         }     }     return 0;

See:

http://e2e.ti.com/support/microcontrollers/stellaris_arm/f/471/p/155813/861350.aspx#861350

  - and replace ''TI'' with ''ST''.The same applies to uIP.
