ASI SDK Issue

Sun Jun 9 04:40:36 BST 2024

TL;DR I tried again and it failed again (though after a little while--it
got 25+ exposures OK before failing).
Then I tried with the ZWO program asi_camera_test and it also failed there.
When I switched back to the previous ZWO software I had no issues, all
worked.
I believe there's an issue with the new ZWO software and ASI1600 cameras.
Can you ask ZWO?

Details:

I don't know what ASIStudio is, but there is a program
called asi_camera_test in the indi-3rdparty/indi-asi directory.

Repeating tonight.
Instead of bothering with my LED panel, I tried shooting "Sky Flats" in the
eastern sky around sunset.
It successfully shot all 25 flats with my L filter, but when it started
shooting the R flats it failed, just like yesterday.
(The L exposures were .2, .02, .002, .0025, .00431, and then it passed the
ADU test and took 24 more at .00431).
Then it started with L at .2 seconds, and failed three times and quit.
Indi panel on my asi1600 driver says:
2024-06-09T02:55:01: [ERROR] Exposure failed after 3 attempts.
2024-06-09T02:54:55: [ERROR] Exposure failed after 3 attempts.
2024-06-09T02:54:50: [ERROR] Exposure failed after 3 attempts.

At this point I stopped KStars and went to the program asi_camera_test that
was built in the indi-3rdparty/indi-asi directory.
The output is below (seems to have FAILED running a 0.1s exposure).

Failed to capture an image: 3
ASI Camera Test completed successfully
______________________________________________________________

When I look at the source code for the "Failed to capture an image: 3", the
3 is the ASI_EXPOSURE_STATUS output of
from /usr/include/libasi/ASICamera2.h which just says:
 ASI_EXP_FAILED,//:exposure failed, you need to start exposure again

I guess I can conclude from that that it isn't KStars/Ekos.  It may be my
cameras, I suppose, but given that things work with the old SDK, I doubt it.

BTW, after all that I tried again (repeating the same thing from the start).
It didn't capture anything in the Flats section, failed right away.
Ran asi_camera_test, failed same way again.

Then I ran 'git checkout' on the submit before the ASI API update, and
recompiled/reinstalled indi, and ran again.
Everything worked perfectly well, all 175 flat exposures and the
asi_camera_test program--no issues!

Seems to me it's clearly the new ZWO software.

Do you have a way to ask ZWO?
