아두이노: NX 마운트 커맨드 추출기

지난 번에 테스트삼아 만든 아두이노 프로그램을 좀 더 손을 봐서,  본격적으로 NX마운트에서 올라오는 3번핀의 CMD를 안정적으로 추출하도록 했습니다.

이 프로그램으로 NX10 바디가 전원을 켰을 때나, 렌즈가 마운트 되었을 때, 안정적으로 바디의 CMD를 수신할 수 있는 것도 확인했습니다. 상당한 성과입니다.

아래는 이 프로그램을 심은 아두이노로 추출한 NX10이 30mm 렌즈를 장착한 상태로 전원을 켰을 때 추출된 CMD의 값들입니다.

 05 10 06 50 08
 05 10 06 50 09
 06 10 08 50 01 01

그리고 아래는 AF 동작시 추출된 바디의 CMD 신호의 값들입니다.

 07 11 01 40 0C 01 C6
 07 11 01 50 FF 02 71
 07 11 01 80 FF 00 00

모두 로직 애널라이저로 확인해 본 결과 일치하는 값들이었습니다.

    Hello!!!

    I have a Samsung NX 11 camera.
    Actually i’m using a micro nikkor 55 mm AI-S f2.8 manual lens.

    I am tryng to make your circuit with stm32f103rbt6 LC STUDIO pcb board and CooCox ARM Cortex MCU Development Tools.

    This is the comunication between camera and my stm32 board :

    Begin:
    03 AA 55 00_
    00 03 10 01 00 00_
    05 10 06 50 01 00_
    05 10 06 50 02 00_
    05 10 06 50 03 00 05 10 06 50 07 00_
    05 10 06 50 08 00 05 10 06 50 09 00 05 10 06 50 0D 00 05 10 06 50 0E 00_
    06 10 08 50 01 00 00 00 00 00 00 00 00 00 00 06 10 08 50 01 01_
    06 10 08 50 01 01_

    but i have a response problem with 06 10 08 50 01 cmd.

    when i receive 6 10 08 50 01 from camera, i send the sequence 3 20 01 04 70 02 03 but the camera not respond.

    Could you help me ?

    Best Regards

    Luca Pellati, Italy.

    Great respect for yours job !!!!!!

    i have dump data from 20 mm f2.8 samsung lens:

      Luca,

      Thank you for your visiting my blog. I have to take a look your code dump and I need to remind the logic what is going on. 🙂

      Please allow me some time to recall my memory. I will get back to you soon.
