TFTLCD-640*480을 쓰고 있는데...
qwsmouse_qws.cpp파일을 구해서 다시  컴파일하고 실행해보니...터치 스크린이 되긴하는데..
x축하고 y축이 바뀌어서 나옵니다...
===============================
x축이 480이고 y축이640으러 나오면서

x축으러 (오른쪽으로)점을 움직이면
y축의 (밑으로)점이 움직이고..

x축으러 (왼쪽으러)점을 움직이면
y축의 (위로)점이 움직 입니다...
===============================
게시판 글 이리저리 읽다보니 밑에 부분을 수정하면 된다고 하는데...
몇 시간동안 이리저리 바꿔 보면서 해밨는데.. 도저히 안되네여..ㅜ.ㅜ
답변점 부탁 드립니다..ㅜ.ㅜ 한번 수정하고 컴차일하고 보드상에서 볼려고 수십번을 넘게
했는데...미치겠습니다.ㅜ.ㅜ
