QHY168C USB Traffic setting not working in build 4008

Post by Excalibur » Tue Sep 12, 2017 6:15 pm

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
