NEC 및 rc-6 이외의 다른 프로토콜 (현재 기본 설정)의 스캔 코드를 얻으려면 간단히 사용할 수도 있습니다.
ir-keytable -c -p all -t

그러나 불행히도 ir-keytable -t는 디코딩 된 스캔 코드의 프로토콜을 보여주지 않습니다. 제대로 작동하려면 프로토콜이 키맵 파일의 헤더에 포함되어야하기 때문에 유감입니다.
따라서 일반적으로 키맵 파일을 만들 때 단일 프로토콜을 수동으로 설정하는 것이 가장 좋습니다.
ir-keytable -c -p nec -t

아시아의 많은 박스가 NEC 프로토콜 리모컨과 함께 제공되는 것 같으므로 -p nec시작하는 것이 좋습니다. 그 시도를 작동하지 않는 경우 -p rc-5나 -p rc-6,이 또한 매우 인기있는 프로토콜입니다. 여전히 아무것도 얻지 못하면 다른 것을 시도하십시오.

# Keymaps table
#
# This table creates an association between a keycode file and a kernel
# driver. It can be used to automatically override a keycode definition.
#
#
# Format:
#      driver - name of the driver provided via uevent - use * for any driver
#      table -  RC keymap table, provided via uevent - use * for any table
#      file - file name. If directory is not specified, it is first looked up
#              in /storage/.config/rc_keymaps, then /usr/lib/udev/rc_keymaps
# 사용방법
# systemctl stop kodi
# systemctl stop eventlircd
# ir-keytable -p NEC,RC-5,RC-6,JVC,SONY -t
# ir remote scan
#
# ir-keytable -a /storage/.config/rc_maps.cfg -s rc0
# systemctl start eventlircd
# systemctl start kodi
#  nano /storage/.config/rc_keymaps/LGUplus
#    첫줄에 정보 필수 삭제 하면 동작 되지 않습니다

# For example:

이게 잘돼야 할텐데.....

시도!
