hex codes and methods of commands to camera
Posted: 22.07.2017 04:37
Hello friends at helicon. I am hoping you can help me!
I am trying to make an arduino board for night time photography of milky way. I am running it to libgphoto2 which I understand is very similar to the way helicon might work for pc and mobile, mostly be hex code being issued and received to camera via PTP protocol. it is an open source camera control project for PC written in C.
The issue is i have poured over the functions in libgphoto and cannot for the life of me find the hex codes for issuing command to camera for bulb capture and movie recording. Every other camera function appears to be present. I have also received canon and nikon SDK from them and cant find it in the documentation.
I noticed however helicon remote has these features, bulb and movie recording. Is there any way you can share hex values of what they are?
in particular i am looking for the hex codes to
start bulb exposure
end bulb exposure
start movie recording
end movie recording
i think i have actually found the start and end movie recording for nikon cameras in the SDK. I think they are
0x920A StartMovieRecInCard
0x920B EndMovieRec
but i cant find the rest. Any ideas? Are you able to help me??? Really ive tried searching the internet but havent been able to find anything! Are you able to point me in the right direction?? thank you
