I am using daq mcc118 to continuously acquire data on raspberry from 4 sensors, saving data on a csv file (programming in python3). I noticed that sometimes when I stop the code with "Ctrl + C" or when the code stop for an error, then at restart of the code the daq does not start the acquisition. I wrote the command "hat.a_in_scan_cleanup()" before and after the active scan to be sure to have free scan resources, but this did not solved the problem. What can be the cause of this behaviour? Thank you in advance
