안녕하세요?
W5500 Chip이 내장된 Wiz550Web Ver 1.1 모듈(MCU : STM32F103RCT)을 사용하고 있는 사람입니다.
현재 회사에서 StmCubeMX를 이용하여 프로젝트를 수행중이라 StmCubeMX Driver를 이용하여
TCP를 구현하려고 하고 있습니다.
하지만, StmCubeMX HAL Driver를 이용하여 GPIO 및 SPI, UART를 셋팅해서 프로그래밍을 했는데
SPI의 Receive 데이터가 이상한 값이 들어옵니다.
며칠밤을 새면서 봤는데도 무엇이 잘못됐는지 모르겠어서 여러분들의 의견 좀 들어보고자 합니다.
감사합니다…
제가 프로그래밍한 소스 내용을 올려드리겠습니다.

위와 같이 설정을 했지만 결과값은 이상하게 나옵니다…
검토 부탁드립니다…ㅠ
