FYI, here are two ways to pass user variables to the callback without using local functions (untested): - Use [functools.partial](https://docs.python.org/3/library/functools.html#functools.partial) ``` def callback_with_extra_param(extra_param, task_handle, every_n_samples_event_type, number_of_samples, callback_data): ... callback =...
