Storing voltages readings to a csv file

[mll]

Hello, I'm currently trying to use example ULAI06 from the mcculw library for the USB-231 to capture the data that is being recorded in Channel 0 of the DAQ. Is there a way I can save those values to the internal memory of the USB-231 before exporting that data into a CSV file?

Additionally I'm scanning at 20khz so uploading the value and storing it to the csv one step at a time may not be possible

Hello @mll.

The USB-231 only has a small 4k data FIFO, enough to transfer the captured data over to the host system and into a user buffer.  There is no other memory to store large amounts of data on the USB-231.

Download and reference the Create a file for storing the data section in the a_in_scan_file_2416.py example of the following post.
