Nuvoton init config

TCP/IP Chip W5500
1

I am using w5500 with nuvoton MCU. I can’t set my init settings. I am checking from the ip scanner application. I’ve written my code snippet below. Can you help me please?

void cs_sel(void) {
CSB = 0;
}

void cs_desel(void) {
CSB = 1;
}

uint8_t spi_rb(void){
uint8_t rbuf;
rbuf= SPI_READ_RX(SPI0);
return rbuf;
}

void spi_wb(uint8_t b){
SPI_WRITE_TX(SPI0,b);
}
reg_wizchip_cs_cbfunc(cs_sel, cs_desel);
reg_wizchip_spi_cbfunc(spi_rb, spi_wb);

wizchip_init(bufSize, bufSize);

wiz_NetInfo netInfo = { .mac = {0x00, 0x08, 0xdc, 0x1d, 0x29, 0xd7}, // Mac address
.ip = {192, 168, 1, 36}, // IP address
.sn = {255, 255, 255, 0}, // Subnet mask
.gw = {192, 168, 1, 1}}; // Gateway address

wizchip_setnetinfo(&netInfo);
wizchip_getnetinfo(&netInfo);
void SPI_Init(void)
{
SPI_Open(SPI0, SPI_MASTER, SPI_MODE_0, 8, SPI_CLK_FREQ);
SPI_DisableAutoSS(SPI0);
SPI_SET_MSB_FIRST(SPI0);
}

In my opinion, this content alone can’t solve the problem. It seems that the SPI communication itself does not work, and it may be faster to contact the nuvoton forum for that part.

I’m really sorry I couldn’t solve it.

I solved the problem. Thank you.
