I have just posted a new version of the Graphical Timing Software package to NI-Labs (
http://www.ni.com/labs/). This package offers support for the PCI-5640R (as well as R Series and most cRIO products) and a different approach to writing LabVIEW applications. Specifially for the PCI-5640R are three free-running nodes that model the clock distribution circuitry (including the CDC7005), the ADCs and the DACs. In addition to consuming normal LabVIEW dataflow wires (for one time static configuration), these nodes produce and consume timing and data information on non-dataflow, asynchronous wires.
This package replaces the host side approach to programming the card. The 5640R is instead completely configured from the fpga target VI. The host VI uses only the nodes in the FPGA Host Interface palette. I've attached the user manual so you can take look without downloading and intstalling from the zip file. The IF-RIO specific nodes are described towards the bottom of the document.
If you have another project coming up that uses the 5640R I encourage you to download and try out this new programming model. This is what I used for the DVB-T NI Week 2007 Keynote Demo that ran on the 5640R.
Thank you.
