Hi,
Could I ask if you've considered adding the option to use an external reference signal in place of ref_X?
Would it be straightforward to add this feature?
Thanks for creating this super useful project!

I tried installing the requirements.txt but pip complained that mkl is not available. I commented the 'mkl' line on requirements.txt and proceeded:
pip
ipython
# mkl <========

Hi, I came across your project which really looks awesome! Thanks for sharing!
After cloning the repo I tried to start the main program DvG_Arduino_lockin_amp.py and got the following error:
line 23: from dvg_pyqt_filelogger import FileLogger
ModuleNotFoundError: No module named 'dvg_pyqt_filelogger'
Apparently this file is currently not part of the repo.
