Dear Jan,

I am sorry but I need to report another problem in 2.0.10. Tested using the QHY5LII-M and QHY5LII-C.

If I link my application against 2.0.10 and connect to either of the two cameras detailed above and then change the gain control a few times, the camera goes offline (that is, it stops streaming). If I link my application against 1.0.2 (no code changes) then everything works as expected.

Can you look into this?

Many thanks Amanda

Amanda,

I do not exactly understand. Just have to say, that the streaming (video) mode is not implemented in linux

code, just GetSingleFrame is. Or are you talking about something else ? 

As I said yesterday, I work the whole days on a new SDK with QHYCCD company which should be the same for all platforms. Furthermore, I need to do that very quickly because guys from company add a new code there,

so we may be not fully synchronized yet. I this problem is easy, I could fix it, but otherwise I cannot do that right now. I apologize to you and others, but wee need one source code and not two separate branches.

Thank you,

Jan

Dear Jan,

Sorry, let me be a little more specific.

I am using GetQHYCCDLiveFrame() under Linux to get frames from the camera if the exposure is under 1000 ms. If the exposure is above 1000 ms then I use GetQHYCCDSingleFrame().

If the exposure is under 1000 ms (using GetQHYCCDLiveFrame()) and I change the gain a few times then the camera stops delivering frames and needs to be reinitialised.

I have observed this problem in SDK versions 2.0.7 and 2.0.10 but not in 2.0.6.

Hope that makes sense.

Kind Regards Amanda
