i'm not exactly sure what you have changed, and I'm not familiar with the CP6-CS, but perhaps there is an issue with the firmware loader fxload. Run "sudo apt-get install fxload" to see if you have it installed or what version you have running.

jmh

Thank for your quick reply. Before trying hte "sudo apt-get install fxload" command, I have an other comment. Apprently, the gain and offset is not available in the capture module nor in the INDI control panel . When I send a get_indiprop, gain and ofset are available the inova camera but not for the QHY8 .. Is this normal ?

Best regards.
JC

I haven't used this camera for awhile and I can't recall if the gain and offset were available with the revised firmware and/or driver. When I get some time, I'll connect my QHY8 and see what the INDI panel shows. What version of qhy driver are you using?

Regards,

jmh

What I get from indi_getprop:
QHY CCD QHY8-C-010103XX.DRIVER_INFO.DRIVER_NAME=QHY CCD
QHY CCD QHY8-C-010103XX.DRIVER_INFO.DRIVER_EXEC=indi_qhy_ccd
QHY CCD QHY8-C-010103XX.DRIVER_INFO.DRIVER_VERSION=2.6
QHY CCD QHY8-C-010103XX.DRIVER_INFO.DRIVER_INTERFACE=18

Thank jmh for your help.

JC

I will add ...
when I keep by indi_getprop the driver interface I have :
QHY CCD QHY8-C-010103XX.DRIVER_INFO.DRIVER_INTERFACE=18

But on the INDI control panel, I get 22...?

This day off inFrance, I try other HEX files... Instead of QHY8V2.HEX, I tryed QHY8L.HEX and QHY8PRO.HEX. With those HEX file, the gain is available in the capture module. And the offset and USB speed are available in the INDI control panel but... when I start an acquisition, the image is always dark...(...and even if have chage the offset and the USB speed is not changing ( always fast )...
I am questioning agout those HEX file generation which seems to the answer of my acquisition problem.
How are they build ( in C, other lagage, compiled with ? ...) . If no devloppers can do the update, where can I find the input to corrected if to be compatible with my CP6-CS camera.

I am quite familiare with C,C++,linux GNU or makefile and I fill confident to adjust it for INDI. I have already mad the job for a home made mount application under Raspberry that I made compatible as a LX200 GPS mount.

Here under I put all the INDI properties that I Get with the QHY8V2.HEX release that can show clealy that no GAIN nor Offset properties nor USB speed has been declared:

The sky is cloudy...But we know that clear night are always comming !

JC,

Sadly, the camera is an older camera no longer properly supported by the new driver. I don't know how many EKOS/indilib users have older cameras (support for the QHY9S may also be deprecated shortly as well) but perhaps a gentle lobby from users to QHY may help. I think they'd prefer that we purchase new cameras ...

I was thinking an older vintage driver, perhaps a few years old, might be able to be dusted off and used instead, but I haven't had the cycles to dig through the archives for one. Perhaps some of the maintainers might know where to look, or even indicate if this is possible.

Regards,

jmh

Thank you jmh for your reply.

I am totaly understanding your answer ! So the way will be be hard ... I will try this WE to generate a customized CCD driver interface ( based on github.com/openastroproject instruction ...) And we will see.

Have clear night !

JC

If you want to play again with the QHY8, I let you know that I finaly succed. I had to recompile the Indi 3rd library for the QHYCCD patching the possibilities to use the gain Offset and low speed USB necessary to used this Cam. The last item I not succeed is patching the driver for using binning 2X and 4X useful for MAP or accelerating the atrometry resolution. But it works now for nominal acquisition.

Have a nice sky.
JC

I would keep watching this topic. I tried to replace the .HEX file with the one provided here. www.qhyccd.com/bbs/index.php?topic=5789.0 I was able to connect QHY8 afterward but there is no way for me to control the gain and offset of the camera.

Hi Reticyte

If you are using the hex file you have mentionned, you will not be able to use gain/Ofsset and USB speed ( you need to slow with the camera... )
To get those functionalities I succed ( After almost one year....) to find how in re-compiling the QHY 3rd driver modifying ( very slightly... ) in the code test concerning those three prperties.
I have recompile for rasbian buster with Astroberry environnement.

The small remaining bug is that when you stop the camera during acquisition, the connexion is completly jamed. But here also I found a way with a unix command in reintialisation to restart the connexion. This permit to avoid a deconnexion of the usb cable which was necessary before. I plan to use Ekos in remote at 500 km from where I am living so I was wondering not to move each time the connexion was out !

So If your are using astroberry/Rasbian , I can send to you those released of QHY 3rd Driver if you are interrested in (without garanty ...! ) or is you are confident to recompile the drivers in your environment, I can show you the modification done in the code whiche is very small. As you want ..

JC

Wow, that was quite an effort you made, I am currently using Astroberry + EKOS, I believe your work will solve my problem. If you don't mind, would you send me the driver first so I can get the camera to work on Astroberry?

Meanwhile, I am also curious to know what kind of modification you did to the driver to make it work, maybe I can look into the jammed connection problem with some digging and lucks.
