Hi,
I'm new(ish) to using LabVIEW and the cDAQ modules, though at work i've been asked to devise a logging system whereby we can log signals from pressure transducers in order to detect pressure spikes/vacuums that are harming a customers system.
I've managed to create a very (poorly) designed program that will monitor the twelve channels and log pre-trigger and post-trigger samples to a TDMS file.
However, my problem lies in that I need to be able to trigger both spikes and dips in the signal, independently on each channel. For the life of me I can't figure it out and unfortunately my non-programming background hasn't helped me pick it up.
I also need to make it so that the end user can select the channels which to monitor and/or record from, as well as configurable sample rates etc.
I'm not very familiar with anything other than the express vi's which doesn't help, but i'm more than happy to put the effort in to figuring this out, I just need some help!
Thanks for your time!
