I am using NiDAQmx driver 8.6. The nicaiu.dll does not appear to be included with this version of the driver. I would like to control S-series NI devices through matlab 7.2. I need to synchronize multiple devices and to trigger them all simultaneously. The Matlab Data Acquisition toolbox (ver 2.8.1) seems to allow control of the trigger sources for each device. But it does not seem to support manipulation of the trigger channels directly. For example, there is no straightforward way to interface with RTSI nor PFI channels. My thoughts are that I must interface with the driver C functionality as an entry point to driver through matlab. The only way I have found to accomplish this in my searching is through matlab loadlibrary command which calls for the usage of 'nicaiu.dll'.
loadlibrary('nicaiu.dll','nidaqmx.h','alias','myni');
Hence I would like to know how to obtain the 'nicaiu.dll'. The 'nidaqmx.h' is included in the driver software. Or I am all ears to entertain other means of trigger control and manipulation through matlab. And, no I am not interested in any Labview solution. I am hoping the NI has provided a means for interfacing in a straightforward manner with their equipment that does not require LabView.
