네 감사합니다. 이제 ping 문제도 해결되었고 소켓 접속과 종료까지는 되고 받는 데이터를 그대로 UART로 쏘게 했는데요 아마 데이터 사이즈 많큼 다 보내는것 같습니다. 그리고 이 뒤에는 소켓 접속 하고 종료도 잘 되고 그러는데 데이터는 쓰레기 값이 계속 올라옵니다.
제가 보내는 데이터는 "1"인데 FC 든 A0 든 이런 쓰레기값을 계속 보내는거 같습니다. 보내는 데이터를 바꿔도 같은값이 올라올때도 있고요…
MCU가 쓰레기값을 보내는동안 SPI 통신에서 MOSI와 MISO핀에서도 일정한 데이터가 계속 올라오고 그럽니다.
아마 MCU에서 보내서 그런거 같은데 RCR 레지스터를 수동으로 클리어 해줘야 하나요?
