Synch settings get lost (SDM 1.81)

Hi (Microfunguy),

I use (as you may still know) version 1.81. for my IXUS 860.
If I use standard SDM 1.81 (downloaded form http://stereo.jpn.org/eng/sdm/index.htm) I face a problem:

Under menu Stereo->Synchronisation I enabled 'Enable synch' and 'Enable synch delay'.
If I take a photo using the USB switch everything is fine.
But if I use the built in shutter-button, take a photo, then synch settings get disabled again.
That means under menu Stereo->Synchronisation 'Enable synch' was disabled!?!
And in the camera, which is set as 'left camera' also 'Enable synch delay' was disabled!?!
Also on SDM info bar (the one which is blue on right cam and red on left cam, which shows DIRECT: Zoom 55 F Synch 0.000), does not show the SYNCH information anymore.

So taking a photo witout USB switch (e.g. if I don't want to take a stereo photo) makes it necessary to re-enable this settings again.
Since I want to hard-wire my cams (to get rid of the external USB switch) it is very annoying to enable synch settings after each photo I take.

What I am doing wrongly? Is it a bug or a feature?

By the way, this happens also with 1.80.

Thanks for information,

best regards,

Mr. Burns

Correct.
I often advise kite aerial photographers that is a quick way to disable synch mode.

A feature.

If you are going to hardwire your cameras, you will have to change the SDM source-code anyway.

I can obviously give you advice on that when you are ready.
Only one other person attempted this but unfortunately damaged his camera before we started altering the code.

I still have the code ... somewhere.

Hi Microfunguy,

I am ready ;-)
I would really appreciate if you can provide me some details which function / code I have to change.
I really need to keep the sync settings after pressing the shutter button!
I hope you can provide me the changes for version 1.81.

Thanks a lot in advance!

Hi Microfunguy,

I don't want to hurry or disturb you, but can you tell me when/if you can give me some hint on this problem?

Thanks a lot!

In \core\kbd.c, search for ' if (kbd_is_key_pressed(KEY_SHOOT_FULL))conf.synch_enable=0; '

Hi Microfunguy,

I found this code in core\kbd.c, can I just remove or comment this code to keep synch-settings?

Just comment it out.

There may be other places where synch is turned-off, just search the entire source-code for 'conf.synch_enable'.

Hi Microfunguy,

I just commented it out and it worked partially now. After taking a photo, setting is as follows:

Enable synch keeps enabled
Enable synch delay still gets disabled

This means synchronisation still not working, especially if I use the flash!  :-[

I searched for conf.synch_delay but nothing found.
May I got the wrong var name.

Can you assist again?

Thanks a lot!

Is this the left camera or right camera ?

There is no delay on left camera because its flash fires immediately but at 1/16th power.

Only the Enable synch delay gets disabled on left camera!

if I enable again, then 'Synch:0.0000' is displayed again and I get synchronized images even using flash!

But I see now, the Enable synch delay gets disabled already if I half press the shutter button !?!
