[w5500] stm32f405 SPI3 DMA 설정

Question

안녕하세요 w5500을 가지고 펌웨어를 개발하고 있는 개발자 입니다. 사용하고 있는 MCU는 STM32f405이고 SPI3을 가지고 w5500과 DMA를 통하여 통신을 할려고 합니다.

W5100S-EVB MUC가 stm32f103vc이며 DMA 프로젝트가 있습니다. github.com W5100S-EVB/DMA at master · Wiznet/W5100S-EVB master/DMA W5100S-EVB Library and Examples. Contribute to Wiznet/W5100S-EVB development by creating an account on GitHub. 위의 프로젝트를 참고 하시면 좋을 것같습니다. 올려주신 code는 확인하는데 시간이 좀 걸릴 것 같습니다. 추후 확인 후 다시 답변드리겠습니다.

안녕하세요 답변이 늦어 죄송합니다. CS에 관한 설정이 보이지않는데 확인해보시길바랍니다. 또한 SPI3_DR의 값이 (uint32_t)(&(SPI3->DR)) 위와 일치하는지 확인해보시기 바랍니다.
