Linux python example issues #8

Closed maltefuchs closed 6 years ago

maltefuchs commented 6 years ago

Hey

I recently purchased a Helios DAC and I`m having problems using the python example for linux.

I used an oszilloscope to display the output of the DAC and to eliminate any influence of other hardware. If If run LaserShowGen on OS X everything seems to work fine. The DAC is recognised and frames are shown just fine (even though somehow distorted on the oszilloscope).

However if I try to run the python example file on Ubuntu (also on a macbook) the DAC is recognized and loads the first frame but gets stuck afterwards. I tried to analyze the problem further and found that after loading the first frame HeliosLib.GetStatus(j) keeps returning 0, so it`s never ready to receive another frame.

I tried using a frame with fewer points (down to 1) but nothing changed. I also tried changing the flags of "int WriteFrame" in all sorts of combinations but wasn`t lucky either.

Has anyone observerd something similar or has any ideas how to solve the issue?

Thanks a lot for any help!

Kind regards Malte

Hi, I checked and it seems the library .so file in the python example folder was outdated. I recompiled from the source and updated the file in the folder, and it fixed the problem for me. So now it should work as-is. Try again and let me know.
