Simultaneously reading multiple channel types programatically

[tommorey]

Hi, I'm completely new to using NI DAQ so please forgive me if this is trivial. I am need to be able to simultaneously read 5 analog lines and up to 20 digital lines of an M-series multifunction card completely programatically, i.e. with no involvement of MAX, LabView, etc. (it's going to be incorporated into a Matlab program and has to be as independent as possible). I simply want to write a piece of C code that reads these channels at 2KHz and stores the data for later analysis. Is this possible with the NI DAQ library? (and if not, why not?) From what I've read so far, for some reason it doesn't seem to be a supported function of the DAQ library. Any advice welcome. Many thanks
Tom

Your M series board is not supported by the old NI-DAQ driver. It can only be used with the newer DAQmx driver included with the board. and while you can't have true simultaneous analog acquisition you can synchronously acquire 5 analog channels 20 digital inputs. The DAQmx driver includes some C example programs. You can download the latest version of DAQmx by going to http://www.ni.com/support/.

If you're not going to use LabVIEW for the data acquisition, you shouldn't post to this message board. There is a dedicated Multifunction DAQ forum and Measurement Studio vot VC++ message board.

Ah... thanks and sorry for posting on the wrong board, my mistake!
