Please synchronize frame numbers to trigger

Thank you for your feedback regarding improvements to our frame timing.

Regarding the remote control of the camera via various methods:


* The Chronos doesn't run a windowing system like X11, both the video feed and the Qt GUI are directly rendered to the frambuffer in this case.
* We're a few weeks out from another release that should contain trigger config settings on the webpage that should work for most users' needs. Do you mind me asking what your triggering requirements are like for your setup?
* For the time being, the best way to handle remote triggering would be with your own calls to our Python API here: https://github.com/krontech/pychronos#io-group (while also acknowledging that it takes some time and effort to work with our API)

Thank you for your reply. Our triggering setup is a plain 50/50 pre/post trigger. I was just using the trigger setup as an example for settings that are not yet in the webpage.

Another detail in the webpage that could be fixed: The framerate is shown as an integer, while in the camera GUI one decimal place is shown. For scientific uses like synchronising video frames to oscillograms it is important to know the interframe time precisely.
