PCI-6528 question

[billko]

Hi, Guys:

I have almost zero experience with Digital I/O - is it possible to do pulse width modulation with a PCI-6528?

Sorry it's dumb question, but like I said, I have about zero experience doing Digital I/O.

It doesn't need to be precise timing, do you think maybe I can do a brute force software-timed solution?  I was hoping for a more elegant solution?

I've done it using counters... with DO its possible, consider using 'regeneration mode' and 'dynamically updating user buffer data' should be selected.

For analog output, 'dynamically updating user buffer data' is explained here. For 'regeneration mode' refer this. See if you can club these together.
