QtCDB2 / Blog: Recent posts

There are now 64 and 32 bit version installers. In tests it looks like 64bit version has better countrate like same 32 bit version. So now its possible to change 64 bit version to use bigger 2D histograms, but it needs to be changed in sources till matrix size is hardcoded in histproducer.cpp.

There are 64 bit drivers availiable in WDDASK3.1 for adlink, so I tested to made 64bit QtCDB2 version. Corrected sources are now in git. To compile it you need to compile your own 64bit Qt and 64bit Qwt, use switch -no-stl in qt configure step.

According to hardware changes, its good to change ADLINK PCI-9820 input impedance from 50Ohm to 1,5MOhm, for this its needed to open pins J7 and J6 by soldering. Pins are on bottom side of the card under Ch0 and Ch1 connectors.

Today I made setup package, thanks to Nullsoft for their NSI application. I will put it to Downloads area, when new QtCDB2 version will be finished.

In old zip file some dll were missing.

Binary version fow win32 (works under win64 too) in downloads. Thread bug was cleared. Some videos are in youtube http://www.youtube.com/watch?v=OAbGnG31IfA, presentation from ICPA-16 is here https://skydrive.live.com/redir?resid=FE16443E81EBB980!473 (It has 165MB)

First alpha version of the QtCDB2 is now in git. It could be compiled using QtDesigner under windows. Its still some buggy, something is wrong with Qthreads, so you have to wait some time after program is closed. My version was compiled using Qt 4.8.2 Msvc version, VS2010 Express as compiler, and Qwt 6.0.1. This version of the QtCDB has also temperature loging from SpeedFan to check relation between temperature and calibration changes, you have to look which temerature is usable for you, it depends on used temperature sensors on mainboard, numbering is same like in SpeedFan application.
