The FPGA Interface palette that includes the "Open FPGA VI Reference" and "Read/Write Control" function is installed by LV FPGA. This will show up at the bottom of the Functions palette, in text form instead of the usual images of icons.
It may not show up depending on the target of the VI that you are attempting to use it in. If the target of the VI is a “FPGA Target”, the palette does not show up. If the target of the VI is “My Computer”, then there may be an issue with the installation of LV FPGA.
In LabVIEW 8, the bottom left hand corner of the VI window will show the target of the VI.
I’m not sure why the LV FPGA Interface is not in the Functions Palette. What version of LV FPGA have you installed? I think it is a version 8 beta.
I have two suggestions.
1. Copy the files that you found in the
2. Uninstall NI 5640R, NI RIO, and LV FPGA. I have put the released version of LV FPGA up on our ftp site: ftp://ftp.ni.com/support/rf/ni-5640r/install/
The file name is: LV-FPGA_8.0.zip
The password is: niifrio
Install the released version of LV FPGA. When installing, there is a screen that shows components that will be installed. Ensure that LabVIEW 8 is on one of the line items to install files to.
After installing LV FPGA, check the Functions Palette for the FPGA Interface palette.
If these two suggestions do not work. I suggest that you post this question to the "LabVIEW" and "Real-Time Measurement and Control" message boards. The experts on LV FPGA monitor those boards more than this one. This one is actually hidden from most users.
Then reinstall NI RIO and NI 5640R
