Re: ASI Linux SDK 0914 beta

Actually, there's another little oddity with this version and the previous one. It's not a big issue because it's easy to correct in my initialisation code, but I thought I'd mention it since I've noticed it. When my ASI120MM starts, it appears to have the image vertically flipped by default. That i...

Re: New to here and planetary imaging

If you download and install the beta version of FireCapture it has an option to check for newer versions which will get you the latest beta. Support for the ASI cameras is much better in the beta versions.

Re: ASI Linux SDK 0914 beta

I've just noticed that this problem happens at 640x480, but not at 1280x960.

Re: ASI Linux SDK 0914 beta

My capture application uses milliseconds for the exposure time, whereas I believe the exposure control uses microseconds. I multiple my values by 1000 when I call setValue(). With my ASI120MM in 16-bit mode, if I use an exposure of 36ms (so 36000 microseconds) everything works fine. But if I set an ...

Re: Linux capture application

I had it the other way around. I had assumed the 16-bit data was big-endian, but it looks as though it is actually little-endian.

Can you confirm that is correct, Sam?

Thanks,

Re: Linux capture application

That certainly means I can now see an image. I suspect the data is big-endian and I have assumed little-endian, but I can work on sorting that out.

Re: Linux capture application

Actually, is 16-bit (or 12-bit) mode supported at all by the SDK for the ASI120MM? If I try setting it I just seem to get a black (or very dark) frame.

Re: Linux capture application

In 16-bit mode, is the data stored big-endian or little-endian?
