how can I save the data from Labview FPGA

Solved!
Go to solution
  • I had only learned labview for several weeks, because I need to use 1MS/s to generate the sine wave and receive the signal for 400kS/s and save the data for 5 minutes.
  • As I know labview real-time (RT) only work for 1kHz for a loop, so need to use the FPGA to generate the signal, but the problem is how can I create the file and save the data?
  • I need to save the generate the signal and receive the data at the same time and save the hole data as much as possible.
  • As the NI9222 example code, it made FPGA to receive the data and show the wave in RT chart, but that will lose too many data so I can’t analyze it.

Hi,

 

you need to do all file access in the RT host, the FPGA cannot do that.

There are example projects explaining how to transfer data from/to FPGA, even at high sample rates...

Dear GerdW :
I'm appreciate for your answer.
That means I can only save the analyzed data in RT.
And try to use another way to proof the data is reasonable....   Smiley Frustrated
