# [Chip]SPI DMA기능을 쓰려면 어떻게 해야할까요?

## Question

Asked by irina on 2018-07-13 in General.

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.
