Intermittent data acquisition using FIFO on LabVIEW FPGA

[watashin]

Hello,

I am working on a project where I need to acquire data using FIFOs. I can get the FIFOs to acquire data continuously, but I only need to get data when certain conditions are met (e.g. while one of the output signals remains within a certain value) . Is there a way to acquire data using FIFO intermittently?

Thanks for the reply in advance,

Shin

You should be constantly reading from the DMA FIFO.  You do not want that the overflow.  But what you can do if have a loop that just reads the DMA FIFO and then only passes data to another loop via a queue.  You only enqueue the data when you have your "interesting" data.
