Hi,
We have not received an updated copy of labView to 8.6 yet, but I need some of the blocks from 8.6 for my application. Is it possible to get access to any of the blocks for 8.6, specifically the FPGA FFT block?
Thanks,
Patrick

Vinay,
I am trying to use the FFT block with an NI-5640R board. The FPGA VI does not have any errors but when I start to compile, I get Xilinx compile errors:
ERROR:HDLParsers:3312 - "C:/NIFPGA85/srvrTmp/LOCALH~1/NIF6AB~1/case_12aaf5bc_frame1_11cefb38.vhd" Line 692. Undefined symbol 'UNDRIVEN_INPUT'.

I have attached the FPGA VI screen shot of where I implement the FFT code. I would like the FFT to run continuously and constantly send the FFT data back to the Host.

Sorry, that was the wrong file. Here is the correct FPGA VI image.

Patrick,
Can you please zip the project and send it to me? Its difficult to know why the error is occuring just from the snap shot.
Also, can you please post the same question to the owner of the FFT block on the same page from where you downloaded it?

edit: sorry, wrong answer - I've misread the numbers of the total memory usage message.

Hello Patrick,
your compiler crashes because of this:
Total memory usage is 249924 kilobytes
It's the 2G-limit of your 32bit-OS. I had the same problem for a while until I read that there is an optionto increase available RAM for programs.
For XP searchwords (for eg google) are: boot.ini /3gb
For Vista: /increaseuserva bcdedit
After that your program should compile.
Greets,
Lars
