thank you very much
Hi,
See
<http://people.mech.kuleuven.ac.be/~kgadeyne/software/pprts/drivers/comedi/ni660x/>
for detailed documentation and some example programs using the ni660x
driver for different applications. I don't think you'll need
comedi+rtai, as I see you will be counting on the card and then using DMA.
The current version of the driver has no support for using an
external clock, however it is trivial to extend the driver, with that.
See eg.
<http://people.mech.kuleuven.ac.be/~kgadeyne/software/pprts/drivers/comedi/ni660x/TODO>
Commands are also not supported yet.
I never looked into DMA for the card too, but you'll probably find
some information in the register level manual about that too.
regards, and have fun,
klaas
