삼성 SSG 1000 3D 셔터 글래스

장인어른댁에서 얻어왔는데

커넥터가 s-video 도 아니고 전용 커넥터?!?!. 아니.. usb가 아니었네!??!

 

 

검색해보니 PDP 용으로 나온거 같은데.. PDP 에서 전용 

 

PDP 깐느 PN50A450

3d sync out 이라고 써있는 3핀 커넥터.. s-video도 아니고 이건 머라고 찾아야 하나

[링크 : https://podol.tistory.com/entry/641]

 

The glasses were made for Samsung's 3D ready DLP HDTV's and Samsung Plasma HDTVs that were compatible with 3D Checkerboard.

VESA stereo  라고 불리기도 하는 듯?

nvidia tensor core

싼거 샀다 피보는 중 ㅋㅋㅋ

 

cuda core는 fp32나 fp64 행렬 단일 연산(곱/덧셈 등..) 에 특화 되어있고

tensor core는 복잡 정밀도의 (AxB) + C 에 대한 연산에 특화되어있는 것으로 보인다.

 

cuda core 로는 

AxB 를 먼저 수행하고(fp32) 거기에 +C를 해서 두번의 연산이 필요했다면

tensor 코어는 (A x B) + C 에 대해서 한번에 하드웨어 적으로 퉤~(물론 정밀도 희생)

 

복합정밀도, 복합 행렬 연산(FMA - Fused Multiply Add)

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

[링크 : https://www.i-pex.com/ko-kr/who-we-are]

 

아무튼 회사에서 평범하게 보던게 MHF1 인것 같은데

intel 8265ngw m.2 무선랜카드의 커넥터에 꽂아지지 않길래 찾아보니

ipex인건 맞는데 MHF 라는 다른(?) 명칭이 더 있다고..

[링크 : https://m.blog.naver.com/just4u78/222131170259]

 

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

그 안에 EDID 파일에 접근하면 i2c로 바로 받아오는 듯.

그나저나 4k(세로) 72Hz만 지원하는건가?

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
