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. 1. Clock 설정 - Wiz550Web Ver 1.1 은 외부 크리스탈 12MHz를 사용하였습니다.

Maybe it could help others who have same problem with this user. Why don’t you give it a try to use an international language that every one else can understand? --- Source: https://maker.wiznet.io/forum/12628
