wacom intuos pro / intuos 5 + 무선킷 획득

윈도우에서 하려니까 드라이버 다시 깔고 리부팅 하라고 해서 했더니

pth-660만 인식되고, 이전에 사용하던 pth-651이나 pth-650이 인식 안되는 문제가 발생 -_-

 

장치관리자에서는 Wacom Tablet으로만 뜬다.

 

아무튼 얘가 BT로도 되는 애라서 해보니 두개가 잡히는데.. 무슨 차이지?

일단 배터리는 0% 뜨는데 하루 충전해놨으니 다시 봐야겠다.

 

pth-650/651 무선킷 usb 연결 하면 아래와 같이 장치가 뜬다.

 

모델별로 드라이버 버전이 난리인지.. 이것저것 아주 중구난방..

pth-660

 

이건 pth-650

윈도우에서 하다가 승질나서 리눅스로 시도

pth-650 + 무선킷

 

Wireless Accessory 라서 WAC f004 라고 뜨는건가?

MD1200 SAS 케이블 검색

SAN 장비라고 해야하나 이녀석 연결용 케이블이 품목에 없어서 찾는중

MD1200 케이블로 검색하니 W390D 라는 품목이 나오고

[링크 : https://www.ebay.com/itm/235840141905]

 

그냥 SAS 커넥터로 하니

커넥터 정보로 찾아보니 여러가지가 나오는데

SFF-8644 는 커넥터 안에 연결되는 부분이 2개이고

SFF-8088은 1개다.

 

Dell MD1200은 구형이라 그런가 8088이고 6GB, 8644 는 12G SAN 으로 검색된다.

근데 양방향이라던가 이런거 구성하려면 케이블이 몇개 필요하지?

으아아 4개(!!!!)

작동은 3.3V

GPIO 입력 범위는 5V. RS232 같은거 아닌 i2c / ttl uart 등은 문제없이 볼 수 있겠네

high는 2~5.25V 라서 1.8 / 1.3V TTL은 무리고 3.3V 쪽까지는 무리없어 보인다.

CY7C68013A on linux

ez-usb 를 리눅스에서 어떻게 하지 찾아보는 중.

일단은 plugdev로 인식시키면 되는건가?

 

요게 영향을 주는진 모르겠다.

sudo usermod -a -G plugdev $(whoami)
sudo vim /etc/udev/rules.d/99-ezusb.rules

[링크 : https://github.com/mbed-ce/fxload]

2026.09.06

패키지를 두 개 설치해야 한다.

요건 pulseview gui 프로그램

$ sudo apt-cache search pulseview
pulseview - sigrok logic analyzer, oscilloscope, and MSO GUI

 

요건 fx2lafw 펌웨어 패키지

$ sudo apt-cache search fx2lafw
sigrok-firmware-fx2lafw - Firmware for Cypress FX2(LP) based logic analyzers

 

윈도우는 짧던데.. 싶어서 다시 보니 윈도우는 장치목록이 스크롤 생겨서 그랬던 듯.

fx2lafw를 선택한다

 

scan  하면 똭!

 

음 좋아좋아 잘되네

 

+

만약에 이런 에러가 난다면 펌웨어 패키지 없어서 그러니, 가장 위의 패키지 중 펌웨러를 설치해보면 될 듯.

이름만 바꾸면 되려나?

 

zadig가 포함되어있진 않다.

 

zadig에서 드라이버 설치하기 전에는 이렇게 "scan for devices using driver above" 버튼을 눌러도 아무것도 안뜨는데

 

zadig에서 winusb로 교체하고 나서 scan을 누르면 cypress FX2 with 16 channels 라고 뜬다.

 

하고나서 보니 fx2lafw 라고 이름이 바뀌어있다. 아까는 그냥 이상한 이름이더니 머냐?

 

PORT B / PORT D 순서로 채널이 사용가능하고 총 16채널

Jumper Instruction

Jumper cap of 24C128: controlling the ability of data reading and writing. Plug in the cap, AT24C128 is closed; remove it, AT24C128 is started.
Jumper cap of D1, D2: controlling the power of LED light. Plug in the cap, the anode of LED 1 and 2 will be connected to the positive pole of power source through resistance. Remove the cap, the anode of D1 and D2 will be open.
