chart to excel file in fpga target

I am a new user of LabVIEW.please help me. I want to export the data to an excel spread sheet from a waveform chart (FPGA Target). suggest me a solution.
Also give me a suggestion for sampling in FPGA target.

Hi,

 

Which FPGA Target you are using? FlexRIO or CompactRIO?

 

There is a few ways to transfer data from FPGA to computer, you can refer to the following topic for more detail information:

 

 

Transferring Data between the FPGA and the Host (FPGA Module)

http://zone.ni.com/reference/en-XX/help/371599F-01/lvfpgaconcepts/pfi_data_transfer/

 

Once you choose the method of communications, you need to save your data into an excel spreadsheet.

Do you need to generate a graph automatically in the excel? If yes you might need a report generation toolkit for this.

Else, you can use the "write to spreadsheet.vi" to log your data.

I found a great example in the community, you can refer to the link below:

Hi, 

 

How fast you would like to acquire the data from FPGA to host?

the data should get updated along with the chart
if its not possible, anything in minutes willd o
please give me the solution.

You have to know your requirement, are you looking for lossless acquisition for the maximum sampling rate? or a slower sampling rate at Hz?

 

If you are looking for latest data acquire by FPGA, you can use programmatically front panel communication.
