034. Raspberry Pi 라즈베리 파이 - RASBIAN 3.5인치 터치스크린 사용하기 (raspbian 3.5 inch touch TFT LCD use)

전부터 고민만하다가 3.5인치 터치 스크린을 처음 구입했습니다

사실 초기 설정 뒤로는 전부 원격접속해서 쓰느라 필요가없었는데

3D 프린터 제어용으로 구입해서 설정을 잡아줬습니다

박스 개봉

LCD가 깨질세라 포장은 엄청 잘해놨네요

 

pi에 조립해줍니다

프린터로 pi케이스를 만들까 고민했는데 케이스 세트 주문하니 편하네요

 

LCD를 안넣고 나사를 조이면 조립이 안되지만 가 조립이니..

오른쪽이 완성

 

LCD를 연결만하면 하얀화면에 아무것도 안나오니 드라이버를 설치해야합니다

* 구입한거랑 설치한 드라이버가 달라서 하단에 다시 설치하니 참고하시길

 

드라이버 등 자세한 자료는 아래 사이트에 있네요

설마설마 했는데... 설치하고나니 pi가 자동으로 재부팅이 되네요

출력중이였는데...

 

근데 재부팅해도 백지화면...

 

음...?

이런 드라이버를 다시 찾아야겠네...

메뉴얼에 OS설치부분만 언급해서 제대로 안봤는데

사이트 URL이 하나적혀있네요
