안녕하세요?
아래의 LG 리모컨을 활용해 보기 위해서 키값을 생성해보고 있습니다.
1. 리모컨 특징
앞면 뒷면 존재 뒷면에 풀 키보드 및 마우스 패드 존재
이어폰 기능 마이크 기능 존재
블루투스 페어링 시 키 페어링 이어폰 페어링 단계 있음
그런데 살짝 키반응은 느린편입니다 ㅎㅎㅎ..
<페어링 방법>
우측 아래 지우기 버튼 꾹 누르고 리모컨 초기화
가운데 U+ 메뉴 꾹 눌러 페어링 모드 진입
BT RCU 먼저 페어링
EARSET 페어링
페어링 후 아래의 2개 장비가 페어링 되어야합니다.
2. 안드로이드 키 값 프로파일 작성
이전에 볼륨 키 고장나서 홈키를 볼륨키로 쓴다거나 할 때.. /system/usr/keylayout/qwerty.kl 파일을 수정해 보신적이 있으실 껍니다. 그 방법을 활용하여 작성해 보는 것입니다.

Vendor_046d_Product_c294.kl Vendor_1689_Product_fe00.kl
내용을 보면 아래와 같습니다.

AVRCP 는 블루투스 이어폰의 버튼 값을 나타내고 있습니다. 이걸 참고하여 작성해야하는데..
Vendor_046d_Product_c294.kl <-- 아니 벤더 프로덕트 이걸 어디서 찾는지 모르겠습니다.
그럼 /proc 을 뒤져서 찾아봐야합니다.

Vendor_00c4_Product_0080_Version_0213.kl 이런식으로 파일 이름을 작성하시면 됩니다.
대부분 버전은 빼고 넣습니다.
자 그럼 키 값은 어떻게 찾느냐..
일단 evtest 를 설치하고 /dev/input 으로 이동하여 이벤트가 몇개 있는지 봅니다. 그리고 cat eventX 하여 버튼을 누를때마다 반응하는 것이 있을 것입니다.

evtest 로 키 값 리스트와 눌러보면서 키값을 찾으실 수 있습니다.
그럼 Generic.kl 파일을 가져와서 수정 후 Vendor_00c4_Product_0080_Version_0213.kl 로 만들어 넣어주면 됩니다.
3. LG RCU 키값 작성...
다음에... 제작 후 과정 공개합니당..
