RE: W5500 hangs when creating the socket

I figured, just in write_spi(uint8_t wr_byte); needed to add a function read to read the first byte read differently corresponded previously accepted values.
void write_spi(uint8_t wr_byte)
{
SPI_I2S_SendData(SPI1, wr_byte);
while(SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
SPI_I2S_ReceiveData(SPI1); /* that’s what was missing */
}
Everything is working.
