Log data only while digital input is true.

[kirving]

Hi,

A stuipidly simple question I know, but I'm trying to log data to a TDMS file, only while a digital input(switch) is true). I think I need a DAQ loop and a Logging loop, but I'm unsure how to correctly set up the logging loop. Is it case of just putting the logging loop inside a case structure?

Thanks,

Kevin

I would recommend having a DAQ loop and a Logging loop.  To do this properly, you should look into the Producer/Consumer architecture.  In short, you use a queue to send the DAQ data to the logging loop.

Now for you extra requirement.  Use a case structure so that the daq data only gets enqueued when your line is true.
