Reading data from a text file in LabVIEW FPGA

[Benvalet]

Hello,

I was wondering whether there is a way I can read file from a text in LabVIEW FPGA. I managed to configure how to read file from the host end as shown in the attached VI. Anyone with an idea of how I can handle this will be highly appreciated.

Thank you.

Kind Regards,

Opuk

Hi Opuk,

whether there is a way I can read file from a text in LabVIEW FPGA.

Don't wonder: there is NO way…

You need to read the file either in your host PC or in the RT host. Then transfer the read data to your FPGA using direct control access or FIFOs - as is shown in the example VIs…

GerdW,

Thanks so much for your prompt response. Let me try and use the method suggested.

Gerdw,

Finally I figured out how I could read the data directly in LabVIEW FPGA but not from a text file. I have actually used Look-up table to solve my problem and the thing now works pretty well.

Thanks a lot for helping out.

Kind Regards,

Opuk

Hello Dear,

I am very new to LabVIEW i want to send the boolean data from excel file to the DIO port of DAQ 7831R that contains FPGA. Also if i connect directly the output of matlab to the Connector port FPGA there is error of datatype that the sink is FPGA I/O type.

How can i change this the boolean data to this type in labview fpga or if this not how to send the boolean data from excel file to the FPGA I/O port of DAQ board

can you please help me in this regard

THanks

Use a DMA FIFO to send the data from the host to the FPGA.

Thank you 

i am trying to send the digital output from mathscript to DAQ 7831R board. So for this i have created a simple vi in that i have generated the digital data and i have created the FIFO in labview fpga module with boolean datatype. Is this way to go is correct or not??

Sounds like you are on the right track.

Dear Sir,

Please see the attached file.

I am doing like this using mathscript 

but here i just took a simple example but its showing the error.

Hey,Can you share details ow you used look up table in labview FPGA environment
