Hi all,
based on reading of your messages, I would like to add the following:
The original qhy driver worked mostly for Windows, but there was a little support for Linux and Mac. The driver was and still is a combination of classical programming in C and basic OOP techniques in C++. This combination is very difficult to understand because you change some part of the code somewhere and this has an influence on other part(s) of the code. I will not go to the details, so what we are doing now is moving the code to follow the OOP rules.
Since version 2.0.0, there is, for example, quite new detection and support for multiple cameras. The driver should support up to 5 cameras now. This still requires a litte modification when user unplug some camera on the fly and plug another one. The driver itself utilizes asynchronous support (bulk transfer) from libusb including multithreaded support from linux, so it has to be done very carefully.
The main problem is, that I have to support all previously released driver's I/O funtions and do all changes behind that scene to be fully backware compatible. These are reasons, why it goes not so fast I would like to do... The good thing is that I have mostly all QHYCCD cameras to my stock, which helps with development very much.
Thanks for your understanding.
Jan
