i-pex 커넥터 MHF1 / MHF4L

i-pex는 회사 이름이자 브랜드 명이라고 한다.

그 일환으로서, 기업이 바라보는 모습을 명시함과 함께, 글로벌 브랜드 인지도의 확대를 도모하기 위해 2020년 8월부터 사명과 브랜드를 [I-PEX(아이펙스)]로 통일했습니다. 앞으로도 그룹의 모든 임직원이 [I-PEX] 아래 하나가 되어, 독자적인 기술,상품,솔루션을 제공하여 세계에서 신뢰받고 사랑받는 글로벌 브랜드로 성장시켜 나가겠습니다.

I-PEX = Innovative Product development & Engineering solutions eXpert

아무튼 회사에서 평범하게 보던게 MHF1 인것 같은데

intel 8265ngw m.2 무선랜카드의 커넥터에 꽂아지지 않길래 찾아보니

ipex인건 맞는데 MHF 라는 다른(?) 명칭이 더 있다고..

i-pex MHF 4L이 M.2의 표준인데 1.2mm 와 1.4mm 두가지를 허용하나보다.

sx1276 raw pakcet

preamble은 빼고 payload + crc 까진 받아볼 수 있다곤 하는데 정작해보니 잘 안된다.

노이즈만 잔뜩.. 멀 빼먹은걸까?

1. Payload CRC 포함 수신 (가장 일반적)
레지스터 설정으로 CRC를 수신 데이터에 포함시킬 수 있습니다.
c// RegModemConfig2 (0x1E) - RxPayloadCrcOn bit 설정
// bit[2] = 1: CRC 활성화
uint8_t config2 = readReg(REG_MODEM_CONFIG_2);
config2 |= (1 << 2);  // RxPayloadCrcOn = 1
writeReg(REG_MODEM_CONFIG_2, config2);
수신 후 CRC 에러 여부 확인:
c// RegIrqFlags (0x12)
// bit[5] = PayloadCrcError
uint8_t irqFlags = readReg(REG_IRQ_FLAGS);
if (irqFlags & (1 << 5)) {
    // CRC 에러
}

2. Implicit Header Mode (헤더 없이 raw payload)
c// RegModemConfig1 (0x1D)
// bit[0] = ImplicitHeaderModeOn
uint8_t config1 = readReg(REG_MODEM_CONFIG_1);
config1 |= 0x01;  // Implicit Header Mode
writeReg(REG_MODEM_CONFIG_1, config1);
Implicit Header Mode에서는:

헤더(Length, CR, CRC 정보)가 전송되지 않음
송수신 양측이 동일한 파라미터를 사전에 알고 있어야 함
FIFO에서 고정 길이의 raw 데이터를 읽음

lora driver for stm32 written in c

매번 찾아도 안나오더니 오늘 검색하니 똭. -_-

구글아 날 괴롭히는거지?

아무튼 c로 작성된 녀석인데.. dio 인터럽트는 사용하지 않고

레지스터 읽어서 (0x12 IRQ flag) 처리하는 쪽으로 구성이 된 듯.

RECEIVE packet routines
uint8_t lora_is_packet_available(lora_sx1276 *lora) Checks if packet modem has packet awaiting to be received Returns 0 if no packet is available, or any positive integer in case packet is ready

uint8_t lora_pending_packet_length(lora_sx1276 *lora); If modem has packet awaiting to be received - returns it's length.

sx1276 spi 통신

CPOL=0 CPHA=0 으로 설정해주고

데이터가 전송되는 동안 NSS를 low로 유지

address 1byte(MSB wnr bit = 1 write, 0 read)

1byte data 로 데이터를 주고 받을수 있는 듯.

아쉽게도 통신 확인용 device id 레지스터는 없는 듯 한데..

그나마 그런용도로 쓸만한게 0x42 RegVersion 0x12 로 리턴되나 보면 될 듯

+

NRESET 핀을 HIGH로 해주어야 sx1276 이 살아나고

그 외엔 정상적으로 잘 읽는 듯 하다.

void sx1276_read_ver()
{
  uint8_t address = 0x42; // RegVersion
  uint8_t data = 0x00;
  uint16_t len = 1;

  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, GPIO_PIN_SET);
  HAL_Delay(500);

  HAL_GPIO_WritePin(NSS_GPIO_Port, NSS_Pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(&hspi2, &address, len, 100);
    HAL_SPI_Receive(&hspi2, &data, len, 100);
  HAL_GPIO_WritePin(NSS_GPIO_Port, NSS_Pin, GPIO_PIN_SET);

  printf("sx1276 ver %X\r\n", data);
}

ver 0 나와서 당황.. -_-

sx1276 ver 0
sx1276 ver 12

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.. -_-

intel i5-7200u 내장 그래픽인데

4k 72hz를 지원하네? dp로 인식해서 가능한건가?

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:

Notebooks supporting Hybrid Power technology are not supported (NVIDIA Optimus technology is supported).
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).
Fujitsu notebooks are not included (Fujitsu Siemens notebooks are included).

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?

3d 셔터 글래스 호환성 및 프로토콜

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.
