ioLibrary functions for w5500

Deepak · July 7, 2020, 3:37pm

I have started working with Wiznet w5500 and read datasheet and posts. In ioLibrary -> wizchip_conf.c -> wizchip_init(), there is no matching condition for w5500. Is there no need or else conditions will be for w5500. I am attaching the file below. Please help me.
Thank you in advance.

int8_t wizchip_init(uint8_t* txsize, uint8_t* rxsize)
{
int8_t i;
#if WIZCHIP < W5200
int8_t j;
#endif
int8_t tmp = 0;
wizchip_sw_reset();
if(txsize)
{
tmp = 0;
//M20150601 : For integrating with W5300
#if WIZCHIP == W5300
for(i = 0 ; i < WIZCHIP_SOCK_NUM; i++)
{
if(txsize[i] >= 64) return -1; //No use 64KB even if W5300 support max 64KB memory allocation
tmp += txsize[i];
if(tmp > 128) return -1;
}
if(tmp % 8) return -1;
#else
for(i = 0 ; i < WIZCHIP_SOCK_NUM; i++)
{
tmp += txsize[i];

	#if _WIZCHIP_ < W5200	//2016.10.28 peter add condition for w5100 and w5100s
		if(tmp > 8) return -1;
	#else
		if(tmp > 16) return -1;
	#endif
	}
	for(i = 0 ; i < _WIZCHIP_SOCK_NUM_; i++)
	{
	#if _WIZCHIP_ < W5200	//2016.10.28 peter add condition for w5100
		j = 0;
		while((txsize[i] >> j != 1)&&(txsize[i] !=0)){j++;}
		setSn_TXBUF_SIZE(i, j);
	#else
		setSn_TXBUF_SIZE(i, txsize[i]);
	#endif
	}

#endif

}

if(rxsize)
{
tmp = 0;
#if WIZCHIP == W5300
for(i = 0 ; i < WIZCHIP_SOCK_NUM; i++)
{
if(rxsize[i] >= 64) return -1; //No use 64KB even if W5300 support max 64KB memory allocation
tmp += rxsize[i];
if(tmp > 128) return -1;
}
if(tmp % 8) return -1;
#else
for(i = 0 ; i < WIZCHIP_SOCK_NUM; i++)
{
tmp += rxsize[i];
#if WIZCHIP < W5200 //2016.10.28 peter add condition for w5100 and w5100s
if(tmp > 8) return -1;
#else
if(tmp > 16) return -1;
#endif
}

	for(i = 0 ; i < _WIZCHIP_SOCK_NUM_; i++)
	{
	#if _WIZCHIP_ < W5200	// add condition for w5100
		j = 0;
		while((rxsize[i] >> j != 1)&&(txsize[i] !=0)){j++;}
		setSn_RXBUF_SIZE(i, j);
	#else
		setSn_RXBUF_SIZE(i, rxsize[i]);
	#endif
	}
#endif

}
return 0;
}

In the wizchip_conf.h, the following define should be set to W5500.
Thank you.

Deepak · July 9, 2020, 8:51am

Thank you for your reply.

I have already changed the defines for w5500 and it was not working that is why i doubt in these condition. But i found the problem was in uC spi configuration which in 4 bit, and i changed it to 8 bit and it worked.

But it is working in local network only, when i am trying to connect remote server connection is not establishing.

My code is given below : -

int main(void)
{
uint8_t rcvBuf[20], bufSize = { 2, 2, 2, 2, 2, 2, 2, 2};
uint8_t dest_ip[4]={147,71,205,253};

void cs_sel()
{
//SPI3_CS_H;
GPIOA->BRR|=GPIO_PIN_15;
}

void cs_desel()
{
//SPI3_CS_L;

  GPIOA->BSRR|=GPIO_PIN_15;

}

uint8_t spi_rb(void)
{
uint8_t rbuf;
HAL_SPI_Receive(&hspi3, &rbuf, 1, 0xffffffff);
return rbuf;
}

void spi_wb(uint8_t b)
{
HAL_SPI_Transmit(&hspi3, &b, 1, 0xffffffff);
}

MX_GPIO_Init();
MX_SPI3_Init();
MX_USART2_UART_Init();

UARTSendString(2, “Ethernet start\n\r”);

GPIOA-> BSRR |= (1<<0); //Init pin

GPIOE-> BRR |= (1<<10); // Reset pin
HAL_Delay(400);
GPIOE-> BSRR |= (1<<10); // Reset pin
HAL_Delay(2000);

reg_wizchip_cs_cbfunc(cs_sel, cs_desel);

reg_wizchip_spi_cbfunc(spi_rb, spi_wb);

wizchip_init(bufSize, bufSize);

volatile wiz_NetInfo netInfo =
{
{0x00, 0x14, 0xA3, 0x75, 0x20, 0x3f}, // Source Mac Address
{192, 168, 1, 100}, // Source IP Address
{255, 255, 255, 0}, // Subnet Mask
{192, 168, 1,1}, // Gateway IP Address
{127,0,0,53}, // DNS server IP Address
NETINFO_STATIC
};

volatile wiz_PhyConf phyConf =
{
PHY_CONFBY_HW, // PHY_CONFBY_SW
PHY_MODE_AUTONEGO, // PHY_MODE_AUTONEGO
PHY_SPEED_100, // PHY_SPEED_100
PHY_DUPLEX_FULL, // PHY_DUPLEX_HALF
};

ctlnetwork(CN_SET_NETINFO, (void*) &netInfo);

HAL_Delay(500);

ctlwizchip(CW_SET_PHYCONF, (void*) &phyConf);

HAL_Delay(500);

wizchip_getnetinfo(&netInfo);

retry:
if((retVal = socket(0, Sn_MR_TCP, 5001, 0)) == 0) {
UARTSendString(2, “socket_created”);
HAL_Delay(800);
if((ret = connect(sock_id_tcp,dest_ip,0x30D4)) == SOCK_OK){
UARTSendString(2, “connected_stablish\r\n”);
HAL_Delay(500);
send(0, “Hello\r\n”, 7);
}
else{
UARTSendString(2, “connected not stablish\r\n”);
}
}
else{
UARTSendString(2, “socket not created”);
}
HAL_Delay(200);
goto retry;

while (1)
{
UARTSendString(2, " Inside while \r\n");
HAL_Delay(1000);
}
}

If i am trying to send data to local ip (192.168.1.24 configure as server using netcat command), It is working find . When i am trying to send data to remote server(147.71.205.253),It is not working.

But when i am sending data from my local network computer (192.168.1.48) to remote server using netcat command, It is sending data.

netcat - Netcat is a tool in linux to test the tcp client server connection. I know it is comman tool, instead i explain it.

Thank you.

W5500 can communicate with external network through gateway.
In order to communicate with the external network, port forwarding must be configured in the gateway.
Or, if an IP is assigned through DHCP, it can be managed by a DHCP server to communicate with an external network.

Deepak · July 9, 2020, 9:18am

As i know port forwarding is necessary when someone want to connect to my local ip. If my need is to send data only, Is there also port forwarding necessary ??

And i am also able to send data from my local computer.

Please assist…

becky · July 9, 2020, 11:17pm

If you think the W5500 on the network is the same condition as the PC and there are no problems,
Make sure the SPI is set up properly
Please read and check if the set IP and MAC address are properly set.

Deepak · July 10, 2020, 6:47am

As I mention earlier that I am able to connect and send data in local network. May I say SPI setup is proper and also IP and MAC address are properly set ??

If yes what should be my next step to identity the problem ??

Alireza_Najafi · June 7, 2022, 12:11pm

Hi Deepak and everybody.

I have been trying to do a project about a local TCP server-client connection between my MCU and Laptop with W5500 module and stm32f4 discovery board. I have seen a number of tutorials and searched through many forums to learn how to configure IoLibrary and get it all working with the MCU. I even implemented the code you put here. But, I still can’t get it right. I’m confused and do not know what the problem is. I get no error while debugging the code, however, I’m not able to find the IP that I’m setting for my W5500 Module in the local network while pinging it. This is why I think I’m not setting W5500 module parameters correctly.
Can anyone help me with this? I’m somehow new to stm32.

I think you can refer to the source code as below link.

Also I think you need to confirm the SPI communication whether or not.
You can try to read the VersionR(0x0039) register of w5500.
If SPI communication works normally, you can see the 0x04 as return value.

Alireza_Najafi · June 9, 2022, 11:37am

Hi dear Irina_kim.

Thanks a lot for your tips. I ran the get_VERSIONR command as the output came out to be 0x04. I also manage to set proper networkInfo on my module and verified they are written successfully. So I believe my SPI connection is working fine now.

There is one problem though. I can’t understand why my module is not responding to the ping command. I also WIRESHARKed it last night and found no trace of my module on the network.
Should I pay attention to my Ethernet configuration and set W5500 parameters in accordance to them or should I use the Wireless LAN parameters? I’m a little bit confused here.

I have chosen these parameters:
volatile wiz_NetInfo netInfo = {
{0x00, 0x08, 0xdc, 0xab, 0xcd, 0xef}, // Source Mac Address
{192, 168, 1, 199}, // Source IP Address {169, 254, 139, 2}
{255, 255, 255, 0}, // Subnet Mask
{192, 168, 1, 1}, // Gateway IP Address
{127,0,0,53}, // DNS server IP Address
NETINFO_STATIC
};

The response to ping command is:
Pinging 192.168.1.199 with 32 bytes of data:
Reply from 192.168.1.198: Destination host unreachable.
Reply from 192.168.1.198: Destination host unreachable.

I have connected my module to my PC via a LAN cable.
