4D 시스템의 gen4 uLCD-70dt 및 PIC18F8722to를 사용하는 프로젝트에서 작업하고 있습니다. 두 디바이스는 한 쌍의 MAX232 직렬 드라이버를 사용하여 연결된다.4D 시스템과의 PIC18F8722 시리얼 통신 uLCD-70-DT
이전에 PIC18F4520을 사용하여이 설정을 브레드 보드했고 시리얼 통신에 문제가 없었습니다. 이제 PIC가 디스플레이에 폴링 요청을 보내면 디스플레이는 응답하지만 PIC는 데이터를 수신하지 않습니다. 코드 ID는 매우 간단합니다 (테스트 용). 그리고 스코프를 사용하는 PIC 핀에서 데이터 스트림, RX RXD TX를 모두 검사했는데 신호가 정상적으로 보입니다. (전압 및 전송 속도 체크 아웃)
나는 온라인에서 발견 된 18F4520 용으로 구축 된 GenieSerial.h를 사용했고 18f8722에 맞게 조정했습니다. (여기에 오류가있을 수 있습니다)
구성 비트 또는 EUSART 설정 비트에 오류가있는 것으로 추측합니다. 어떤 도움이
을 apreciated입니다
