pico real plus on windows

별 언급없으면 win 11

컨트롤러는 HID 규격 마우스로 잡히는 듯

 

모니터로 잡히는데 일반 모니터인건 맞는데 표기법이 다를 뿐이려나. 윈11은 PicoVR이라고 명시된다.

win 11 win10

 

USB Type-C Digital AV Adapter라.. 이건 머지?

 

usb composite device 2개 추가, 일반 usb 허브 1개 추가

 

스피커(USB Advanced Audio Device) 추가

그래서 꽂으면 HDMI 모니터 대신 이쪽으로 소리가 넘어간다.

 

HID 규격 사용자 컨트롤 장치

HID 규격 터치 스크린

HID 준수 장치

Microsoft Input Configuration Device 1개

USB 입력 장치 3개 추가

win10 에서 custom resolution utility 를 통한 덤프

꼬이는 바람에 드라이버 깔기 전으로 복원하고 라이젠 노트북에서 재시도

드라이버를 완전 재설치 해도 안풀리네.. -_-

nvidia 3d vision + doom eternal 실패

doom eternal은 드라이버 버전을 보는지 실해에 실패한다.

442.19 면.. 이유가 왜일까? vulkan 지원때문이려나?

nvidia 3d vision 테스트 - flatout

되는 목록에 flatout이 있어서 시도(용량이 2기가도 안되서 설치가 금세 되서 ㅋㅋ)

눈으로 보면 두개 겹쳐 보이는데, 스샷찍어 보면 정상으로 나온다.

 

기본값 15%

 

중앙의 녹색차를 보면 약간 차이가 난다.

 

100% 하면

 

눈으로는 도저히 촛점을 잡히 못할정도가 되는데, 아무튼 제법 멀리 떨어진다.

 

혹시나 해서 핸드폰으로 찍어보니 IR emitter라는말이 맞게

빨간색으로 송출한다. 이러니까 화면의 반짝임을 이용하는 DLP Ready 안경과는 호환이 안되겠지

nvidia 3d vision 드라이버 설치

당근에서 3만원에 업어온 nvidia 3d vision kit.

예전 글 찾아보니 200$정도 했었고, 그래픽 카드도 나쁜걸 써서 엄두도 못내던 녀석.

15년 만에 가져보게 되었구나..

2011.03.19 - [하드웨어/3D Stereoscopic] - NVIDIA 3D vision kit

 

 

에미터는 머리가 잘린 피라미드 같다.

드라이버 설치해야지 nvidia 로고가 녹색으로 들어온다.

 

nvidia 3d vision 이라는 심플한 모델명.

 

안경에도 nvidia 3d vision model : P854 라고 써있다.

 

드라이버 버전이 높아서 그런가 ir emitter 드라이버 설치되지 않는다.

머 본다고 큰 도움이 되진 않는 VID와 PID

 

판매자분의 조언으로 425.31이 마지막 버전이라고 하셔서 일단 설치!

Please note: Effective April 12, 2018, Game Ready Driver upgrades, including performance enhancements, new features, and bug fixes, will be available only for desktop Kepler, Maxwell, Pascal, Volta, and Turing-series GPUs, as well as for systems utilizing mobile Maxwell, Pascal, and Turing-series GPUs for notebooks.

Following the posting of the final driver from Release 418 on April 11, 2019 GeForce Game Ready Drivers will no longer support NVIDIA 3D Vision or systems utilizing mobile Kepler-series GPUs. Critical security updates will be available for these products through April 2020. A complete list of Kepler-series GeForce GPUs can be found here.

Those looking to utilize 3D Vision can remain on a Release 418 driver. Our software that enables the use of 3D gaming with 3D TVs, 3DTV Play, is now included for free in Release 418.  It is no longer available as a standalone download.  Our 3D Vision Video Player will continue to be offered as a standalone download, for free, until the end of 2019.

Exceptions:
  1. Notebooks supporting Hybrid Power technology are not supported (NVIDIA Optimus technology is supported).
  2. The following Sony VAIO notebooks are included in the Verde notebook program: Sony VAIO F Series with NVIDIA GeForce 310M, GeForce GT 330M, GeForce GT 425M, GeForce GT 520M or GeForce GT 540M. Other Sony VAIO notebooks are not included (please contact Sony for driver support).
  3. Fujitsu notebooks are not included (Fujitsu Siemens notebooks are included).

[링크 : https://www.nvidia.com/ko-kr/drivers/details/145988/]

 

555.85 에서 425.31로 다운드레이드!

 

그 와중에 phys 도 중단되었는지 버전 차이가 별로 없다.

 

NVIDIA Stereo controller 에서

NVIDIA Stereoscopic 3D USB controller로 이름이 바뀐다.

참 오랫만에 보는 그리고 단 한번 lg 3d tv로 성공했던 그 페이지

 

먼가 오작동하는지 번쩍번쩍 하길래 슈퍼슬로우로 해서 프레임넘기며 보니

우 -> 좌 순서로 점멸을 하나 싶기도 하고?

 

참 오랫만에 보는구만

 

4k 60hz에서 하려니 안되네.. 결국은 빔프로젝터 출동! 해야하나?

The kit is specially designed for 120 Hz LCD monitors, but is also compatible with CRT monitors (some of which may work at 1024×768×120 Hz and even higher refresh rates), DLP-projectors, 3LCD projectors and others. It requires a compatible graphics card from Nvidia (GeForce 200 series or later).

드라이버 버전 낮추고, 해상도를 빔프로젝터 120Hz를 지원하는 1024x768로 변경.

 

빔 프로젝터 HDMI로 연결해서 시도. 3D vision 에 정상적으로 사용가능하다고 나온다.

 

그나저나 "내 디스플레이는 3D Ready  이지만 3D Ready로 감지되지 않습니다" 라는 문구가 나온다.

120Hz만 지원하면 무조건 지원한다는데.. 흐음.. 머지?

DLP ready는 3dtv쪽에서 되는게 없는 듯. 완전 프로토콜이 다른가?

DLP Link는 아무래도 흰색을 통해서 하는것 같고

nvidia는 ir 로 하는것 같아서 수광부의 부품이 완전 달라 안될 것 같다.

하모닉 드라이브, 사이클로이드 드라이브

협동로봇에 많이 사용된다는 고단 변속 드라이브.. 라고 해야하나?

 

왼쪽이 하모닉 드라이브, 오른쪽으 사이클로이드 드라이브

 하모닉 드라이브는 총 3개의 부품으로 끝나고(크게) 사이클로이드는 부품이 좀 많이 들어간다.

높은 토크가 필요한게 아니라면 하모닉 드라이브도 괜찮아 보이지만 중간의 유연성을 지는 부품이 핵심일 것 같은데

아무래도 변형되는 녀석이 있다 보니 내구도가 좋지 않을것 같긴한데.. 알아서 잘 해결했겠지 머

LoRa modulation basics

먼진 모르겠지만.. FSK 보단 LoRa가 더 좋다고 보면되려나?

동일한 속도를 내려면 lora가 더 신호가 안 좋아도 되고 (약 -10 dBm)

동일한 감도라면 더 빠른 속도를 낼 수 있다. (fsk 1000bps, -123 dBm = LoRa 10000bps)

lora CR(coding rate)

래핑 모듈만 사용하다 보니, SF / 주파수만 신경썼었는데

sx1276 데이터 시트를 보다보니 CR(Coding Rate)라는게 있어서 먼지 감이 안와서(메뉴얼 상에서는) 찾아보니

 

FEC를 위한 추가 비트를 이야기 하고, 순수데이터/패리티포함데이터 길이로 보면 된다고 한다.

4/5는 4bit data + 1bit parity

4/6은 4bit data + 2bit parity

4/7은 4bit data + 3bit parity

4/8은 4bit data + 4bit parity 식인셈

4.1.1.3. Coding Rate
To further improve the robustness of the link the LoRa® modem employs cyclic error coding to perform forward error
detection and correction. Such error coding incurs a transmission overhead - the resultant additional data overhead per
transmission is shown in the table below.



Forward error correction is particularly efficient in improving the reliability of the link in the presence of interference. So that
the coding rate (and so robustness to interference) can be changed in response to channel conditions - the coding rate can
optionally be included in the packet header for use by the receiver. Please consult Section 4.1.1.6 for more information on
the LoRa® packet and header.

FEC - Forward Error Correction

[링크 : http://www.ktword.co.kr/test/view/view.php?no=693]

 

CRC -Cyclic Redundancy Checking

[링크 : http://www.ktword.co.kr/test/view/view.php?nav=2&no=603&sh=crc]

 

FEC는 전송할때 복구를 위한 데이터를 포함하여 전송하여 correction에 포인트를 두는 전송방식이고

CRC는 정정이 아니라 에러가 있음을 확인하는 방법이다.
