Make Canon Mirror Lockup property writable #913
Comments
|
this is a reporting variable only, setting it will not be possible (although I have not tried). The customfuncs are specific for each camera and are even less documented than the other codes. unless we reverse engineer or USB sniff this more we are out of luck. |

Thanks for the reply and the quick PR! I added a comment regarding the label which I think is wrong. Are there any docs on what makes a property writable? Does the cam report it or how does this work? And this is not about the customfuncex, which works fine for the 450D, but rather the "EOS prop d1bf (EOS_MirrorLockupState) info record" which seems to have replaced it on the 6D. I just saw another property 0xd406 which seems to be setable in the "other" section of the indilib driver, so I thought you "just" need to add a setter for 0xd1bf, too. I'm mentioning it because it's literally named "d406" in the indi window:

And it's setable in EOS Utility 2, so if you tell me how to debug this it can be done: 
|
|
Here's the 2 log files for ON and OFF state set up in the Canon LCD in the hope they help: I commented here: For both EOS_MirrorLockupState and EOS_MirrorUpSetting I got "01" values when I enable Mirror lock in the UI and do --get-config and "00" when I disable it. So I'm not sure which one it is, but "Mirror Up Status" is not PTP_DPC_CANON_EOS_MirrorLockupState. |
hook up 2 other EOS mirror props into config tree. #913
|
ptp (2): event 227: EOS prop d13a (EOS_MirrorUpSetting) desc record, datasize 8, propxtype 3 this seems settable. I hooked it up now as "mirrorup" , you can try to set it |
|
This works great, thanks a lot! I can toggle the lock flag from indi and that's great, as I really can't access the LCD. A few things though:
but that puts stuff in /usr/local and I have to

i renamed it to mirrorlock. i add put_None to the others. |

Works great, I didn't even have to recompile the indi driver. So thanks again!

Closing as fixed |

I want to be able to toggle mirror lock for my Canon 6D.
Apparently the customfuncex solution to toggle the lock doesn't work for it.
https://github.com/gphoto/libgphoto2/blob/master/camlibs/ptp2/canon-eos-customfunc.txt
Instead I found this in the debug logs:
ptp (2): event 3: EOS prop d1bf (EOS_MirrorLockupState) info record, datasize is 4
ptp (2): event 3: Unknown EOS property d1bf, datasize is 4
ptp (2): 0: 01 << currently ON, and this one toggles
ptp (2): 1: 00
ptp (2): 2: 00
ptp (2): 3: 00
Unfortunately this property is not writable. it's not in the --list-all-configs and thus can't be used.
Is there a way to make this property writable? Or are the writable props determined by the cam?
