Error in starting the server in pic18f4520

Question

Hi, I am using the example given for pic18f45k22 to implement the server in the pic18f4520. i was not getting any error while, but server was not starting when controller was programmed. Here is the code: #include "Wizchip_Conf.h" #include "W5500.h" #include "Socket.h" #include // 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]; int32_t WebServer(uint8_t sn, uint8_t* buf, uint16_t port); char proc_http(uint8_t sn, char * buf); void sendHeader(uint8_t sn); void sendData(uint8_t sn); uint16_t calcu_len(void); volatile wiz_NetInfo gWIZNETINFO = { {0x00, 0x14, 0xA3, 0x72, 0x17, 0x3f}, // Source Mac Address {192, 168, 0, 111 }, // Source IP Address {255, 255, 255, 0}, // Subnet Mask {192, 168, 0, 1}, // Gateway IP Address {8, 8, 8, 8}, // DNS server IP Address NETINFO_STATIC }; uint8_t destip[4] = {192, 168, 0, 103}; uint16_t destport = 5000; 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; } proc_http(sn, (char *)buf); } 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; } // Socket is opened with TCP mode case SOCK_INIT : { // Listen to connection request if( (ret = listen(SOCK_ID_TCP)) != SOCK_OK) { return; } break; } // Socket is released case SOCK_CLOSED: { // Open TCP socket if((ret = socket(SOCK_ID_TCP, Sn_MR_TCP, PORT_TCP, 0x00)) != SOCK_ID_TCP) { return; } break; } default: { break; } } } static…

dhanunjay: wizchip_init(buffsize, buffsize, 0, 0, CB_ChipSelect, CB_ChipDeselect, 0, 0, CB_SpiRead, CB_SpiWrite); Is this function modified by you? It is different from ioDriver’s function form. I want you to re-check the code with the following information. W5500 TCP Function Application Guide And, Please refer to other topic below. TCP Server with W5500 W5500 Hi, I’m new with W5500. My project is to develop Ethernet-to-Serial Converter using W5500. The Evaluation board with the chip, SPI interface and RJ45 connector is in its way and I’m currently getting familiar with the Datasheet of W5500. My idea is to start with a very simple MCU application, which to initialize the chip as a TCP Server and establish connection with a TCP Client. Investigating the registers of the chip, I think the following initialization and control sequence will be good …

Looking at your initialization I noticed you assert the Hardware Reset line, apply 1 ms delay, then de-assert the Reset line and apply another 1 ms delay. I would suggest to toggle the Reset line without using any delays, then start polling the PHY Configuration Register (Common Block, Offset 0x2E) for RST Bit (0x08) cleared. This happens in less than 1 ms. From this point you can apply Software Reset and start Register initialization. Below is some pseudo code reflecting this approach. When your initialization is complete, your device should be responding to pinging its IP Address. Good Luck! void InitW5500(void) { // W5500 Hardware Reset PORTCbits.RC1 = LOW; // Put W5500 in Reset (Active Low) PORTCbits.RC1 = HIGH; // Bring W5500 Out of Reset // Waiting for PHY Ready while (!(ReadPHYCFG() & PHY_RST)); // W5500 Software Reset InitComBlkMr(); // Set Network Attributes SetMacAddr(NetAttrs.pMacAddress); SetIpAddr(NetAttrs.pIpAddress); SetSbnMask(NetAttrs.pSubnetMask); SetGateway(NetAttrs.pDefGateway); // Set Socket 0 PORT SetS0PORT(PortNumber); // Default Port Number // Enable Socket 0 Interrupts WriteSIMR(SIMR_S0); // Connection Alive WriteS0KA(KA_TIME); // Set TCP Protocol WriteS0MR(TCP); }
