Is there a technical architecture overview document for the FPGA and NI I/O modules - essentially similar to VxWorks component API manuals? Trying to find any real tech information on this platform has been particularly frustrating. Especially since this is NOT a new platform. I don't need to know the particulars of how the FPGA/IO interface will be set up for FRC, but it would help immensely to know what a typical engineer recieves in terms of documentation, software templates, and information when they buy an cRIO IO module.
Realtime OSes don't necessarily have the same division of kernel and user modes. Specifically, the RIO peek and poke are allowed to be called from user code. As for documents that would be received if an actual engineering customer. To this point, the C/C++ for the cRIO has been for internal consumption. To this point, all cRIO customers have used LabVIEW.

The best source of technical overview info that I know of is http://zone.ni.com/dzhp/app/main.
Search for cRIO. The first five articles or so seem like they may be useful.
