Purchasing the 2009 controller

321 didn't get picked up today because the front desk of the high school wouldn't let him in! Thank goodness the FedEx driver was nice enough to come back and get it for us! - Chuck Glick [more]

I was actually wondering if anyone actually had the opportunity to read the technical specifications for the cRIO and realized there ARE NO INTERRUPTS SUPPORTED ON THE cRIO. I'm guessing not.

Instead of having interrupts, you have an FPGA - the FPGA is a pure polling mechanism, but it's extremely FAST. So, instead of having interrupts taking time away from the main processor, you've got an external unit managing a fast polling strategy for reading external sensors.
