4
Description: The integer value of this attribute ranges from 0-4.
5
When read, this attribute returns the number of the actual
6
profile. This value is persistent, so its equivalent to the
7
profile that's active when the device is powered on next time.
8
When written, this file sets the number of the startup profile
9
and the device activates this profile immediately.

3. 한국어 전문 번역
영어 원문의 문단 순서와 의미를 유지한 전체 번역입니다. 코드, 함수명, symbol과 URL은 원문 표기를 유지합니다.
공통 경로, actual_profile과 info
1-18BASE=/sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/isku/roccatisku<minor>이 문서의 모든 attribute는 위 BASE 바로 아래에 있다. Date는 별도 표시가 없는 한 2011년 6월, contact는 Stefan Achatz <[email protected]>, user는 http://roccat.sourceforge.net다.
$BASE/actual_profile
$BASE/info| attribute | 값·길이 | access | 의미 |
|---|---|---|---|
| actual_profile | integer 0-4 | read/write | 현재 profile과 다음 power-on 때 사용할 startup profile |
| info | 6 byte | read-only | firmware version을 포함한 일반 device data |
actual_profile을 읽으면 현재 profile 번호를 반환한다. 값은 persistent하므로 다음에 device power를 켤 때 활성화될 profile과 같다. 값을 쓰면 startup profile 번호를 저장하고 device가 그 profile을 즉시 활성화한다.
info를 읽으면 firmware version 같은 일반 data 6 byte를 반환한다.
Profile별 key 설정
20-89$BASE/key_mask
$BASE/keys_capslock
$BASE/keys_easyzone
$BASE/keys_function
$BASE/keys_macro
$BASE/keys_media
$BASE/keys_thumbster| attribute | payload | 설정 대상 |
|---|---|---|
| key_mask | 6 byte | Windows·application key 같은 특정 key 비활성화 |
| keys_capslock | 6 byte | Caps Lock key 기능 |
| keys_easyzone | 65 byte | EasyZone key 기능 |
| keys_function | 41 byte | function key 기능 |
| keys_macro | 35 byte | macro key 기능 |
| keys_media | 29 byte | media key 기능 |
| keys_thumbster | 23 byte | thumbster key 기능 |
key_mask를 쓰면 Windows key와 application key처럼 실수로 눌렀을 때 방해가 되는 특정 key를 비활성화한다. 적용할 profile 번호는 6-byte write data에 포함된다.
keys_capslock, keys_easyzone, keys_function, keys_macro, keys_media, keys_thumbster를 쓰면 각각 특정 profile의 해당 key group 기능을 설정한다. 모든 payload에는 profile 번호가 포함된다.
이 일곱 file을 읽기 전에는 control에 먼저 값을 써서 어느 profile data를 읽을지 선택해야 한다.
last_set, light와 macro
91-119$BASE/last_set
$BASE/light
$BASE/macro| attribute | payload | profile 선택 | 의미 |
|---|---|---|---|
| last_set | 20 byte | payload contract에 따름 | 마지막 configuration 시각의 epoch seconds |
| light | Isku 10 byte / IskuFX 16 byte | payload에 profile 번호 포함 | profile별 backlight intensity |
| macro | 2083 byte | payload에 profile·button 번호 포함 | 특정 button에 최대 500 keystroke macro 저장 |
last_set에 쓰면 마지막 configuration이 수행된 시각을 Unix epoch 이후 seconds 값으로 설정한다. write data 길이는 20 byte여야 한다.
light에 쓰면 특정 profile의 backlight intensity를 설정한다. profile 번호는 payload에 포함된다. Isku payload는 10 byte이고 IskuFX는 16 byte다. 읽기 전에는 control에 써서 profile을 선택해야 한다.
macro에 쓰면 특정 profile의 특정 button에 최대 500 keystroke의 macro를 저장한다. button 번호와 profile 번호가 2083-byte payload에 포함된다. 읽기 전에는 control을 통해 읽을 profile과 key를 모두 선택해야 한다.
reset, control, talk와 talkfx
121-153$BASE/reset
$BASE/control
$BASE/talk
$BASE/talkfx| attribute | Date | payload | access | 동작 |
|---|---|---|---|---|
| reset | 2012년 11월 | 3 byte | write-only | device reset |
| control | 2011년 6월 | 3 byte | write-only | 다음 read가 가져올 profile과 data 선택 |
| talk | 2011년 6월 | 16 byte | write-only | host에서 EasyShift 기능 trigger |
| talkfx | 2013년 2월 | 16 byte | write-only | host에서 temporary color scheme trigger |
reset에 정확히 3 byte를 쓰면 device를 reset한다.
control에 3 byte를 쓰면 다음 read에서 어느 profile의 어떤 data를 가져올지 선택한다. profile별 file을 읽기 전에 사용하는 selector다.
talk에 16 byte를 쓰면 host가 EasyShift 기능을 trigger한다. talkfx에 16 byte를 쓰면 host가 임시 color scheme을 trigger한다.
Persistent profile과 profile별 key map
sysfs-driver-hid-roccat-isku:1-890-4 profile을 device에 영구 저장하고 key mask, Caps Lock, EasyZone, function, macro, media, thumbster key assignment를 고정 길이 binary payload로 읽고 씁니다.
