Wavemeter as Instreamer

[qku]

Hello, I am creating this thread to discuss the implementation of the HighFinesse Wavemeter based on the instreamer interface. The current state built by @ksenkalla (and others?) can be found in the wavemeter_development branch of qudi-iqo-modules.

I have tested the code with a WS7. After setting the config option calc_digital_freq to false in the config file in the branch, the wavelength of channel 1 of the wavemeter was plotted in the time series gui. So that's already pretty cool!

My main question at this point is if there was a specific reason that you decided to implement the wavelength as a digital channel. Wouldn't analog make more sense for a quantity like wavelength that is more float than integer-like? In the current state, the wavelength is displayed without digits after the decimal, e.g. as 637 nm.

I believe we should consider this before implementing support for different units and multiple channels etc.

Hello,
thanks for your valuable input @qku . Indeed there was no specific reason for this (just starting somehow). We now changed that to an anlog channel considering your argument. You can find it in the updated branch https://github.com/Ulm-IQO/qudi-iqo-modules/tree/wavemeter_development
To track better the progress of this intended new feature I also want to refer to this issue https://github.com/Ulm-IQO/qudi-iqo-modules/issues/59. Hopefully this makes it also easier to think about the next steps and maybe distribute work.
