    The "monitor crashed" you said,is it mean that temperature become a abnormal value,for example,-4096?
    And please not disconnect camera's USB connection when capture,this will make camera device lose,althrough you reconnect it.
    And about the temperature 0,in fact,camera will be setup to 0 degree when you connect power and USB.So you need setup to other value if you want change target.

ok: the code I have sent you is fully compatible with the new Arduino IDE, feel free to reuse if you are developing a new firmware.
Let me know if you want me to expose the backlash settings in the ASCOM driver: I would need the source code for it but it would allow to set the right amount of backlash from the ASCOM setup panel.

What the user are asking is to have the gain available as a selection on the camera tab which requires the use of the CameraDependentSettingInterface to populate an extra menu :

and as said it'll also be available in the take series :

So having it int he settings dialog is onwe thing, but having the option to select it on the camera tab and in take series is what users want so that they can select different value for different exposure/filter/bin ...
Mechanical Q&A / QHY294M usb socket broken
« Last post by yonafunu on May 07, 2021, 12:35:51 PM »

Sorry for my English, I?m a French native person.
After moving out to Montreal, I have tried to run QHY294M pro since I have bought it.
Unfortunately, I have just see the usb socket of the camera is broken (the spacer between the pins). I don?t understand how it is possible, I am a very precautions person and it was maybe the ten time I put the cable in the socket.
I?m very disappointed?since I have it, I never succeed to make it run correctly (connection failure, temperature readout fail?) . Do you think It is related to this issue ? I had several cameras, a majority from your brand, but this is the first time I have so many issue with a camera.
How can I fix this broken part ? I have bought the camera directly QHYCCD in October

Best regards

Image Issue Q&A / QHY268M gain numbers vs gain graphs
« Last post by Johan_B on May 07, 2021, 06:59:06 AM »
Dear Qiu,

I may have started this topic in the wrong category, so I ask it here
as I think it needs someone who knows the ins and outs of the camera to answer my question.

Can you pls inform about the relationship of the
Gain used in the graphs (0 - 100)
the digital number the gain can be given in e.g. the setup window (0 - 339)

Does the gain number in the graphs represent a percentage ?
Is the number 339 equal to 100 % or to 339 % ?

If 339 equals 100 %
then putting gain = 30 in NINA is only about gain = 8.8%

Can you pls provide the correlation between both percentage and the gain number we enter in e.g. NINA

Thank you very much.

On any of my computers, if I place a USB2.0 hub between the camera and the computer, it connects just fine.

It appears that there is an issue when the firmware is loaded and it attempts to enter USB3 operation.
Mechanical Q&A / QHY410C - what is the Bayer pattern?
« Last post by VisualUniverse on May 07, 2021, 12:27:27 AM »
I am attempting to process images captured with the QHY410C. During the debayer step, I need to identify the exact Bayer pattern (e.g. RGGB). I have made attempts with different patterns, but the images either turn out purple or green.
