logitech x-56 플라이트 스틱

 

stick

러더는 z 회전

햇은 그냥 햇인데

x 회전, y 회전은 ace combat에서 시점 조정으로 사용된다.

15번은 어디서 눌린거지?

 

쓰로틀. 별도의 USB 장치로 인식되는게 신기하네..(내껀 본체에 연결해서 하나로 인식되는데..)

그 와중에 스틱보다 축 많은게 포인트.. 얘가 본체고 스틱은 덤(?)

X,Y 회전은 시야로 동일하고

F는 Z축

G는 Z회전

좌측 스로틀은 X축

우측 스로틀은 Y축

RTY 3는 전화걸기(?)

RTY 4는 슬라이더로 할당되어 있다.

윈도우 서비스 프로그램 기본 실행 경로(?)

서비스 프로그램을 작성해서 실행파일과 동일 경로상에

static web을 넣어두었는데 찾지를 못해서 찾아보니

C:\Windows\System32 가 기본 실행 경로라고 한다.

실제로 static web 을 C:\Windows\System32\static 식으로 넣어주니 작동 확인

 

chatGPT 사라사대

Windows 서비스 프로그램에서 GetCurrentDirectory 함수의 기본값은 일반적으로 C:\Windows\System32 폴더로 설정됩니다.

libinput 디버깅 유틸리티

USB HID class 확인을 위해서 /sys/class 라던가 온갖데 찾아봐도 답이 없어서

검색하다가 바로 똭!! 아니 저번에 개고생 할 때 찾았더라면... -_ㅠ

 

우분투에서 아래의 패키지를 설치하고 libinput 이라는 유틸리티를 실행하면 된다.

$ sudo apt install libinput-tools
$ sudo libinput list-devices

[링크 : https://wayland.freedesktop.org/libinput/doc/latest/tools.html]

명령을 실행해서 확인해보면 Capabilites 라고 해서 이 장치에 적용된 기능이 뜬다.

pointer 어우... 얘가 날 잡는구만

USB HID 상세 기능은 출력해주지 않아, 개인적으론 별로 도움이 안되었음

개소리 왈왈/직딩의 비애2025. 2. 20. 22:41

정신이 늙었어..

먼가 불타오르는 것도 없는게

그냥 서서히 죽어간다라는 느낌만 든다

1초 1초 늙는것도 아닌 죽어간다는 느낌

 

회사도 일이 재미없는 것만 할당되고

이상하게(?) 시간만 가고 짜증만 나고..

인기있을 블로그는 아닌데..

요 근래 조금은(?) 하락세에서 반등중

 

그런다고 해서 월별추세로 봐서 올라갈것 같지도 않은데, 검색엔진 유입이라도 생겼나?

10g 또 지름

자꾸 link가 떨어지는데 랜 카드가 문제인지 케이블이 문제인지 몰라서

또 셋트로 지름!

이제 LP 2개, 표준형 2개! ㅋㅋ

 

걍 처음부터 2개씩 살걸..(원래 2배수 지르는 닝겐)

$ candump 
candump - dump CAN bus traffic.

Usage: candump [options] <CAN interface>+
  (use CTRL-C to terminate candump)

Options:
         -t <type>   (timestamp: (a)bsolute/(d)elta/(z)ero/(A)bsolute w date)
         -H          (read hardware timestamps instead of system timestamps)
         -c          (increment color mode level)
         -i          (binary output - may exceed 80 chars/line)
         -a          (enable additional ASCII output)
         -S          (swap byte order in printed CAN data[] - marked with '`' )
         -s <level>  (silent mode - 0: off (default) 1: animation 2: silent)
         -l          (log CAN-frames into file. Sets '-s 2' by default)
         -L          (use log file format on stdout)
         -n <count>  (terminate after reception of <count> CAN frames)
         -r <size>   (set socket receive buffer to <size>)
         -D          (Don't exit if a "detected" can device goes down.
         -d          (monitor dropped CAN frames)
         -e          (dump CAN error frames in human-readable format)
         -x          (print extra message infos, rx/tx brs esi)
         -T <msecs>  (terminate after <msecs> without any reception)

Up to 16 CAN interfaces with optional filter sets can be specified
on the commandline in the form: <ifname>[,filter]*

Filters:
  Comma separated filters can be specified for each given CAN interface:
    <can_id>:<can_mask>
         (matches when <received_can_id> & mask == can_id & mask)
    <can_id>~<can_mask>
         (matches when <received_can_id> & mask != can_id & mask)
    #<error_mask>
         (set error frame filter, see include/linux/can/error.h)
    [j|J]
         (join the given CAN filters - logical AND semantic)

CAN IDs, masks and data content are given and expected in hexadecimal values.
When the can_id is 8 digits long the CAN_EFF_FLAG is set for 29 bit EFF format.
Without any given filter all data frames are received ('0:0' default filter).

Use interface name 'any' to receive from all CAN interfaces.

Examples:
candump -c -c -ta can0,123:7FF,400:700,#000000FF can2,400~7F0 can3 can8

candump -l any,0~0,#FFFFFFFF
         (log only error frames but no(!) data frames)
candump -l any,0:0,#FFFFFFFF
         (log error frames and also all data frames)
candump vcan2,12345678:DFFFFFFF
         (match only for extended CAN ID 12345678)
candump vcan2,123:7FF
         (matches CAN ID 123 - including EFF and RTR frames)
candump vcan2,123:C00007FF
         (matches CAN ID 123 - only SFF and non-RTR frames)

 

$ cansend vcan0
cansend - send CAN-frames via CAN_RAW sockets.

Usage: cansend <device> <can_frame>.

<can_frame>:
 <can_id>#{data}          for 'classic' CAN 2.0 data frames
 <can_id>#R{len}          for 'classic' CAN 2.0 data frames
 <can_id>##<flags>{data}  for CAN FD frames

<can_id>:
 3 (SFF) or 8 (EFF) hex chars
{data}:
 0..8 (0..64 CAN FD) ASCII hex-values (optionally separated by '.')
{len}:
 an optional 0..8 value as RTR frames can contain a valid dlc field
<flags>:
 a single ASCII Hex value (0 .. F) which defines canfd_frame.flags

Examples:
  5A1#11.2233.44556677.88 / 123#DEADBEEF / 5AA# / 123##1 / 213##311223344 /

받는 쪽에서 CAN id 제한할 경우, 112를 받도록 설정했기에 113은 무시된다.

그나저나 mask 라는데 이해가 안되네..

123 = 0x7B & 0x7F0 하면 0x7B가 되어야 하니 16개에 대해서 받아들여야 할 거 같은데 왜 119에서 130 까지 12개 받아들여 질까?
