same here, it's just not "gain" but "Gain (dB/1000)". The "Gain" in ekos CDD capture settings has no effect on the image taken.

Hi Eric

I've found some time for testing this evening.
The camera does recognize the exposure settings send via ekos. I prepared a short sequence with exposures from 0.001 -- 0.060 s and plotted the mean pixel values over the exposure time. To me, it looks reasonably linear which is what I'd expect.

The log file seems to be a little messed up. When triggering an exposure, the log receives data from the previous exposure.
In this case, I took a 1 s exposure before the sequence start. Resulting in:

...
DEBUG	2890.131759 sec	:   Setting Exposure (Absolute) (Exposure (Absolute)) to 10000.000000, ctrl_id = 0x9A0902
...
from the 1 s exposure, followed by
DEBUG	2890.140622 sec	: 0.001-second exposure translates to 10 1/10,000th-second device ticks.
...
DEBUG	2892.939829 sec	: Upload complete
which belongs to the actual exposure.

I noticed that the "Gain" in ekos has no effect on the images, but I have to check that in more details and get back to you.

cheers
Niko

I did check general functionality with IC Capture last week. I didn't do any in deeps checks, I was happy to get a picture at all :)
I'm on vacation right now and don't a have Windows PC with me, so I can't do anything with IC Capture.

For good measure, I added the output of v4l2-compliance, if it's of no use please disregard.

Hi Eric

I fetched PR/299 and made a quick test. The behavior is still the same :(, however, more information ends up in the log-file.
Please let me know if I should run further tests or provide you with more information that might help to solve the issue.
In any case, I'm very impressed to see how fast this is going and that the issue is taken seriously.

Yes, preview makes three attempts to capture a picture.

I was in contact with TIS. They said the camera can only stream, no single frame capability.
Is there a way to still use the cam for guiding? That's what I intended to use it for in the first place.

Hmm, that only happened once. I never saw this behavior later on.

Hi Eric

@VM: yes, VirtualBox hosted on a MacBookPro, USB passed through and started a local indiserver. Same issue as on the RPi.

I noticed the strange values during initialization. However, I also set them via the respective panel to which the camera responded. Also, the CCD panel seems to push the settings before an exposure attempt.

I'll update to the latest version as soon as possible and let you know.

cheers

Hi Eric

I'm using the camera on a RPi3, directly connected to a USB port. However, the same issue is eminent with the EKOS VirtualBox image provided by Jasem.
OS in the RPi is Ubuntu mate 16.04.1 LTS with the ppa from Jasem.
uname -a
Linux INDIPi 4.4.38-v7+ #938 SMP Thu Dec 15 15:22:21 GMT 2016 armv7l armv7l armv7l GNU/Linux

v4l driver version shipped with indilib 1.4.1. If you have a more recent version I'm happy to test it, please provide instructions on how to fiddle it into the system, as I'm new to all this.

I attached the log file, hope that's what you're looking for.

Many thanks in advance and good to hear that I'm not the only person with this problem.

Hi all

I'm new to indilib and I'm stuck at getting a DMK 23UP031 to work.

All's fine with streaming. I can connect the camera just fine and also get a stream to dump a .ser file to the selected folder via the Control Panel.

However, I'm unable to get a single frame grabbed via CDD or Guide taps in the main application. I'm getting a Warning from Main Control:
<< WARNING ... Failed 0.250-second manual exposure, out of device tick bounds [1,300000]

Is there a magic spell to get it working?
Any suggestions would be highly appreciated.

cheers from Switzerland
Niko
