Obtain data from Eth Wiz Click to microcontroller

hi all, im using Eth wiz click and im having some troble interpretating the data sent. Lest say I send a number 5 via a TCP client, I want to be able to read that number through SPI via a microcntoller. Right now im using a example, wich allows to ping the module and to echo any UDP or TCP package. But how do you obtain the data?? I see the datasheet talks about the frames image914×281 27.8 KB and that the return is by send(SOCK_ID_TCP, gDATABUF + sentsize, size - sentsize) but cannot get it to work, any ideas? im using the fillowing code in MikroC thanks. include "Wizchip_Conf.h" #include "W5500.h" #include "Socket.h" // ETH WIZ click connections sbit Wizchip_Rst at LATE1_bit; sbit Wizchip_CS at LATE0_bit; sbit Wizchip_Rst_Direction at TRISE1_bit; sbit Wizchip_CS_Direction at TRISE0_bit; // end of ETH WIZ click connections // Socket & Port number definition #define SOCK_ID_TCP 0 #define SOCK_ID_UDP 1 #define PORT_TCP 5000 #define PORT_UDP 10001 #define DATA_BUF_SIZE 1024 uint8_t gDATABUF[DATA_BUF_SIZE]; volatile wiz_NetInfo gWIZNETINFO = { {0x00, 0x14, 0xA3, 0x72, 0x17, 0x3f}, // Source Mac Address {192, 168, 0, 53}, // Source IP Address {255, 255, 255, 0}, // Subnet Mask {192, 168, 0, 1}, // Gateway IP Address {192, 168, 0, 1}, // DNS server IP Address NETINFO_STATIC }; volatile wiz_PhyConf phyConf = { PHY_CONFBY_HW, // PHY_CONFBY_SW PHY_MODE_MANUAL, // PHY_MODE_AUTONEGO PHY_SPEED_10, // PHY_SPEED_100 PHY_DUPLEX_FULL, // PHY_DUPLEX_HALF }; volatile wiz_NetInfo pnetinfo; // brief Call back function for WIZCHIP select. void CB_ChipSelect(void) { Wizchip_CS = 0; } // brief Call back function for WIZCHIP deselect. void CB_ChipDeselect(void) { Wizchip_CS = 1; } // brief Callback function to read byte usig SPI. uint8_t CB_SpiRead(void) { return SPI1_Read(0xAA); } // brief Callback function to write byte usig SPI. void CB_SpiWrite(uint8_t wb) { SPI1_Write(wb); } // brief Handle TCP socket state. void TCP_Server(void) { int32_t ret; uint16_t size = 0, sentsize = 0; // Get status of socket switch(getSn_SR(SOCK_ID_TCP)) { // Connection established case SOCK_ESTABLISHED : { // Check interrupt: connection with peer is successful if(getSn_IR(SOCK_ID_TCP) & Sn_IR_CON) { // Clear corresponding bit setSn_IR(SOCK_ID_TCP,Sn_IR_CON); } // Get received data size if((size = getSn_RX_RSR(SOCK_ID_TCP)) > 0) { // Cut data to size of data buffer if(size > DATA_BUF_SIZE) { size = DATA_BUF_SIZE; } // Get received data ret = recv(SOCK_ID_TCP, gDATABUF, size); // Check for error if(ret <= 0) { return; } // Send echo to remote sentsize = 0; while(size != sentsize) { ret = send(SOCK_ID_TCP, gDATABUF + sentsize, size - sentsize); // Check if remote close socket if(ret < 0) { close(SOCK_ID_TCP); return; } // Update number of sent bytes sentsize += ret; } } break; } // Socket received the disconnect-request (FIN packet) from the connected peer case SOCK_CLOSE_WAIT : { // Disconnect socket if((ret = disconnect(SOCK_ID_TCP)) != SOCK_OK) { return; } break; }…
