해당 글은 스토어에서 판매하는 USB to CAN 통신 분석기를 can-utils 을 이용해 우분투에서 동작 테스트하는 방법이다. 1. 선 연결 먼저 아래와 같이 두개의 USB to CAN 동글을 각 라인에 맞게 서로 연결을 해준다. 2. CAN0 통신 속도 설정(100Kbps) 후 스캔 모드로 진입 이제 아래의 명령을 차례로 입력하여 CAN0를 모니터링 모드로 진입시킨다. 아래의 사진들은 각각 동작시 화면이니 참고하길 바란다. 2. CAN1 통신 속도 설정(100Kbps) 후 데이터 전송 이제 CAN1도 CAN0와 동일한 통신 속도로 맞춰 준 후 cansend명령을 통해 데이터를 전송해보자. 위 마지막 명령은 CAN1에서 ID [0x123]으로 8바이트 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x7.......
