3. 한국어 전문 번역
영어 원문의 문단 순서와 의미를 유지한 전체 번역입니다. 코드, 함수명, symbol과 URL은 원문 표기를 유지합니다.
Active CPI, profile과 sensitivity
1-40BASE=/sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/kovaplus/roccatkovaplus<minor>
$BASE/actual_cpi
$BASE/actual_profile
$BASE/actual_sensitivity_x
$BASE/actual_sensitivity_y별도 표시가 없는 항목의 Date는 2011년 1월, contact는 Stefan Achatz <[email protected]>, user는 http://roccat.sourceforge.net다.
| attribute | 값 범위 | access | 의미 |
|---|---|---|---|
| actual_cpi | 1-4 | read-only | active CPI level 번호 |
| actual_profile | 0-4 | read/write | active profile과 power cycle 뒤 유지할 profile |
| actual_sensitivity_x | 1-10 | read-only | X 방향 sensitivity |
| actual_sensitivity_y | 1-10 | read-only | Y 방향 sensitivity |
actual_cpi는 active CPI level 번호를 반환하지만 실제로 사용된 적이 없다. CPI 상태 bookkeeping이 필요하면 userland tool에서 수행한다.
actual_profile을 읽으면 현재 active profile을 반환한다. 값을 쓰면 선택한 profile을 즉시 활성화한다. power-down 때 active였던 profile은 다음 power-on 때도 active 상태로 복원된다.
actual_sensitivity_x와 actual_sensitivity_y는 각 방향의 현재 sensitivity 번호를 반환하지만 두 file도 실제로 사용된 적이 없다. sensitivity bookkeeping은 userland tool이 담당한다.
Firmware version과 binary info
42-60$BASE/firmware_version
$BASE/info| attribute | Date | payload | access |
|---|---|---|---|
| firmware_version | 2011년 1월 | raw integer | read-only |
| info | 2012년 11월 | 6 byte | read/write |
firmware_version은 mouse가 보고한 firmware version의 raw integer를 반환한다. 실제 version은 decimal point를 왼쪽으로 두 자리 옮겨 구한다. 예를 들어 121은 1.21이다. 이 file은 binary sysfs attribute인 info로 대체되었다.
info를 읽으면 firmware version 같은 일반 data 6 byte를 반환한다. 6-byte data를 쓰면 device를 reset할 수 있다.
Profile button과 settings payload
62-116$BASE/profile_buttons
$BASE/profile[1-5]_buttons
$BASE/profile_settings
$BASE/profile[1-5]_settings| attribute | payload | access | 내용 |
|---|---|---|---|
| profile_buttons | 23 byte | read/write | 선택 profile의 button layout |
| profile[1-5]_buttons | 23 byte | read-only | 번호별 profile button layout |
| profile_settings | 16 byte | read/write | 선택 profile의 resolution·sensitivity·light effect |
| profile[1-5]_settings | 16 byte | read-only | 번호별 profile settings |
mouse는 button press로 바꿀 수 있는 profile 다섯 개를 저장한다. profile은 settings와 buttons로 나뉜다.
profile_buttons에 23 byte를 쓰면 payload 안의 profile 번호가 지정하는 button layout을 mouse에 기록한다. invalid data는 mouse가 거부한다. 읽기 전에는 control에 써서 읽을 profile을 선택해야 한다.
profile1_buttons부터 profile5_buttons까지는 해당 profile button data 23 byte를 직접 반환하는 기존 read-only file이다. control로 profile을 선택하고 profile_buttons를 읽는 방식으로 대체되었다.
profile_settings에 16 byte를 쓰면 payload 안의 profile 번호가 지정하는 resolution, sensitivity, light effect를 기록한다. invalid data는 거부하며 읽기 전에는 control selector가 필요하다.
profile1_settings부터 profile5_settings까지는 해당 profile settings 16 byte를 직접 반환하는 기존 read-only file이다. control과 profile_settings 조합을 사용해야 한다.
