Example for DMA FIFO Real Time Acquisition of IO Square Wave Waveform

Hardware

  • PXIe-7820

Software

  • LabVIEW

Issue Details

Is there any LabVIEW example of DMA FIFO for square wave acquisition? The hardware used is PXie-7820R.

Solution

There is an example called Finite Acquisition and Generation Simple.lvproj that can be found in the example finder.

While this example is for a finite generation and acquisition, and it could easily be altered to continuously acquire a digital waveform.

Additional Information

For a good example of continuous data streaming, you can look at the Stream Data.lvproj example. While that example is for analog IO, not digital, the same concepts could be used to alter the DIO example.
