QHY168C USB Traffic setting not working in build 4008

#1

Post by Excalibur »

Hello,

The setting for USB Traffic is not working for QHY168c in latest build, it has no effect at all. Since the framerate is always (regardless of what the slider says) high, it appears the used value is always 0 (zero).

The issue can be traced to latest used qhyccd.dll, and begun with the SDK's from May. Reverting to the March-SDK works (which appears to be the version used in previous Sharpcap build).

This problem may be limited to QHY168c, because it works correctly with QHYIII178m.

Clear Skies,
Magnus

Hi Magnus,

can you try copying in the very latest QHYCCD.dll from the last link on this page - http://qhyccd.com/SWHIST_SDK.html - use the x86 version. If that doesn't work then I will raise the bug with QHY, but maybe it is fixed already in that new version.

cheers,

Robin

Hi Robin,

Replacing qhyccd.dll with V2017.09.10.0 had no effect, preview at full speed regardless of the slider/setting for QHY168c.

Working for QHYIII178m.

Sidenote: QHY168C 16bit RAW requires USB Traffic of 1 or higher, or DDR Buffer=on, else there are no frames shown. But since USB Traffic here is broken, 16bit RAW without DDR Buffer is not working.

Clear Skies,
Magnus

Hi,

no, not yet in a 3.0 build. There will be a new 3.1 beta build available before the end of next week which will (I think) fix your problem. You can also if you want follow the instructions on the QHY web site for copying a newer SDK into the SharpCap folder.

cheers,

Robin

Sorry for not getting back earlier, but I have not had time to test lately.

I can confirm that this is now working properly, both in 3.0.4057 and 3.1.4864.Beta. Adjusting USB-Traffic also adjusts download frequency.

Where is the USB Traffic control?

I have a QHY294C and I don't see. I need to throttle it down as my observatory computer is not powerful and is overwhelmed.

It should be under "Offset", but it seems to be missing?
