Digital waveform output

hello everybody

first of all: i'm working with m-series card pci 6259 and measurement studio c++.

i want to output digital waveforms to sixteen digital outputs.
the waveform buffer should contain at least 720 points.
the frequency at which the output should be changed is varying between 24kHz and 120kHz.
when one waveform buffer is done, it must be recalculated, frequency adjusted and output again, and so on...

in the data sheet of my card i read about waveform characteristics of port 0. but i can't find any
documentation about this anywhere.

so can anyone help me with this problem?

regards
markus

The standard installation of NI-DAQmx puts an item into the Start menu: Start->National Instruments->NI-DAQ->NI-DAQmx C Reference Help.

Look under C Functions->Channel Configuration/Creation->Create Digital Output Channels, and Write Functions, various DAQmxWriteDigital... functions.

Look in the NI-DAQmx Concepts section for various kinds of information about digital output.

Look for the C-language examples under Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\.
