1.SPI 통신을 하신다면, wizchip_conf.h에 보시면
/**
* @brief Define interface mode.
* @todo you should select interface mode as chip. Select one of @ref _WIZCHIP_IO_MODE_SPI_ , @ref _WIZCHIP_IO_MODE_BUS_DIR_ or @ref _WIZCHIP_IO_MODE_BUS_INDIR_
*/
// #define WIZCHIP_IO_MODE WIZCHIP_IO_MODE_BUS_DIR
// #define WIZCHIP_IO_MODE WIZCHIP_IO_MODE_BUS_INDIR
#define WIZCHIP_IO_MODE WIZCHIP_IO_MODE_SPI
WIZCHIP_IO_MODE 를 SPI로 선택만 해주시면 사용가능합니다.
2… W5500 + STM32F4xx 를 SPI DMA를 사용한 예제 와 자료가 있습니다.
참고하시면 될것 같습니다.
