Need to fix GPIO_WriteBit() function in
W7500x_StdPeriph_Lib/Libraries/W7500x_StdPeriph_Driver/src/w7500x_gpio.c

please refer to GPIO_ResetBits function.

Hi,
I'm trying to receive a multicast packet, send to ip 235.255.255.250 on port 1900

This is my relevant code:

socket(sn, Sn_MR_UDP, port, SF_MULTI_ENABLE )
while(1)
{
    if ((size = getSn_RX_RSR(sn)) > 0) {
        uint8_t ip[4];
        uint16_t port;
        if (size > DATA_BUF_SIZE) size = DATA_BUF_SIZE;
        ret = recvfrom(sn, buf, size, ip, &port);
        printf("> Receive DNS message from %d.%d.%d.%d(%d). len = %d\r\n", ip[0], ip[1], ip[2], ip[3],port,size);
        if (ret <= 0) return ret;
        buf[size] = "\0";
        printf("%s", buf);
    }
}

But I only receive messages directly send to the IP of the device. So no messages send to 235.255.255.250 are received.

Any ideas?
Thanks!

Hi,
I'm trying to send an UDP message. I cannot find an example, so I figured out the following code:

    #define SOCK_SSDP 7

    uint8_t dest[4] = { 239, 255, 255, 250 };
    #define MDNS_PORT (1900)

    char result[10];
    snprintf(result, sizeof(result),
            "message"
    );

    uint8_t err = 0;
    if(socket(SOCK_SSDP, Sn_MR_UDP, MDNS_PORT, 0x00) != SOCK_SSDP) return;
    printf("sendto: %i", sendto(SOCK_SSDP, (uint8_t*)result, strlen(result), dest, MDNS_PORT));
    close(SOCK_SSDP);

The console prints a positive number (so the total size of the message), but I cannot see this message in wireshark. Am I missing something?

I am currently developing a UART data forwarding application using TCP protocol to transmit data to a PC. The UART data rate can go up to 921600, so I need to utilize DMA functionality to ensure accurate data reception. However, I have been unable to find specific information on this. I would like to ask if it is possible to provide additional APIs related to DMA here?

#define CHECK_SOCKNUM()   \
    do{                    \
        if(sn > _WIZCHIP_SOCK_NUM_) return SOCKERR_SOCKNUM;   \
    }while(0);             \

I think you want this : > and >= off by one error

#define CHECK_SOCKNUM()   \
    do{                    \
        if(sn >= _WIZCHIP_SOCK_NUM_) return SOCKERR_SOCKNUM;   \
    }while(0);             \

Is I2C supported in the library? Which library should I use and is an example available?
Thanks!

Hi,
I'm trying the WZTOE_WebServer example on W7500P with eclipse gcc 4.8q1 on a linux host.

When running the code I get this:

W7500x Standard Peripheral Library version : 1.0.0
SourceClock : 8000000
SystemClock : 8000000
PHY Init : Success
Link : Off
MAC: 00:08:DC:01:02:03
IP: 0.0.0.0
GW: 0.0.0.0
SN: 0.0.0.0
DNS: 0.0.0.0
Start DHCP

Link is Off and DHCP never happens.
Why is the link off and how can I fix this so that DHCP works?

Thanks!
