Dear Friends,
I am working on acquiring pressure sensor signals using LabVIEW with an NI USB-6008 DAQ device. My goal is to record and log the data in real time—specifically, to save timestamped readings of both pressure (P1 to P5) and voltage (V1 to V5) into a CSV file.
Currently, I can display the waveforms in LabVIEW, but I'm facing issues while trying to write the data to a CSV file. I also see the error below. I’ve tried using the “Open → Write → Close” file sequence, but I keep encountering errors with array handling—especially when combining timestamp, voltage, and pressure readings.
Can someone please guide me on:
How to properly structure the data (timestamp, V1–V5, P1–P5) for saving?
How to convert the timestamp to start from zero (like a stopwatch)?
The best way to save the data continuously to a CSV in the correct format?
Any tips to reduce noise or improve accuracy in the measurement?
I’d really appreciate any help, examples, or best practices you can share. Thanks in advance!
