Hello all- I have a very specific use (and need) for the NI-6602 board, so I decided to take a stab at making my own driver using the register level document from NI. I can do some basic setup and testing with the board via registers, but what I really want is to have an external gate cause a hardware latch (no problem), and then generate an interrupt so I can handle the value latched to the HW register. The interrupt part I get stuck on. It seems that either the register guide is incomplete, or (more likely) I just don't understand how to set up the card. Installing an interrupt on the card IRQ doesn't fail in the driver; it is just never invoked. I am guessing that the MITE chip on the board must be programmed to relay the interrupt from the NI-TIO to the PCI bus, but NI doesn't seem to give any information about that in the manual, nor have i been able to find any related documents anywhere. The tech support there let me know that register level programming isnt supported. I would be interested in using Comedi to do more work on the driver, but can anyone tell me where I could find any useful code or documents on this? Will any of the NI drivers used by Comedi resemble this board? Thanks for any help you can give... -Rob Russell
