PCI-6289 rlp, how to get an interrupt every n samples

[jstaniek]

I have a PCI-6289 DAQ card and want to get an interrupt every n samples (the card samples continuously and writes the data as a Bus Master to the PCs memory). Does someone know how to set the registers of this card ??
And another question, is there any register documentation for the PCI-6289 ??
Thanks in advance.

Hi Jan,
It is possible to program this device to use interrupts using the DAQmx driver. I'm not sure which programming language you are using, but there is a relevant example in C that installs with DAQmx. By default, it will install to the following location:
C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage\Cont Acq-Int Clk
If you specifically want to do register level programming, I suggest that you post on the Driver Developer Kit (DDK) board.
Thanks,
