6602 interrupt programming

[Rob Russell]

I have started writing a driver for the NI6602 card (since one does not exist in Linux) and have been using the register level programmer manual as a guide.

I want to use the card in a mode as described in the manual (p. 2-4, Buffered Cumulative Event Counting). I have been able to configure the card to start a counter, and have sucessfully read the HW and SW Save Registers while it is running.

What is the "method" for having an interrupt created on a HW Save (due to a rising gate edge)? I can read the HW Save register after I have created a pulse on the selected gate, but my interrupt handler is never invoked.

I am guessing that some more configuration of the MITE needs to be done, but I can't find any documentation on that.


Also, the "Interrupt Acknowledge" register description seems to be lacking from the manual.

Is there more documentation floating around on any of this?

Thanks...

Rob;

Unfortunately National Instruments doesn't support Register Level applications.

I suggest you to go to www.ni.com and type +register +level in the search field to get access to all documentation posted on line about that topic.
