Introduction
The timeseries toolchain allows to plot the timetrace of an incoming digital or analogue signal in real time. For an confocal setup, the signal might be TTLs coming from a photon counter or the (analogue) output of a photodiode. A typical working toolchain consists out of the following qudi modules:
logic: - time_series_reader_logic
hardware: - instreamer, eg. ni_instreamer
gui: - time_series_gui
Example config
These modules need to be configured and connected in your qudi config file. We here provide an examplary config for a toolchain based on a NI X-series scanner with analogue output and digital (APD TTL) input. Note: This readme file might not be up-to-date with the most recent development. We advice to check the examplary config present in the docstring of every module’s python file. In the list above, a direct link for every module is provided:

Configuration hints:
Make sure that the hardware in the conig file is named as it is called by the logic. (Copy paste out of the hardware file can name it differently).
