Hey,

I'm using the session based commands to control a NI DAQ device with Matlab 2011b 64-bit. Amongst other things I need to trigger some signal generators with a 5V rising edge. Heretofore I used the legacy interface's digital I/Os which can't be used anymore in the 64-bit version.

Which options do I have, if I don't want to go back to Matlab 32-bit?

Best regards Tobi

Hi Tobi,

Support for non-clocked DIO has been added to the Session-based interface in MATLAB R2012b pre-release. If you have a valid license, you can install the prerelease here.

Thanks,

Manisha

Hi Manisha,

thanks! Great news! I was hoping that matlab 2013a will include this support. Now I am happy because 2012b release will be very soon. I think it will take some weeks to get the new license at my university. I already tried to search aditional information about the new Data Acqisition Toolbox's features comming with the pre-release but i didn't find a thing.

Thanks again! Tobi

Hi Manisha and Tobi,

So, are you suggesting that the entire MATLAB R2011b 64-bit does not support digital ports of a NI DAQ ???... I mean, I am having the same problem... I want to use my Digital I/O ports, but I cannot on the session - based interface of the MATLAB R2011b 64-bit.

Is it impossible?? Do I have to either go back to a version with legacy interface or update or R2012b??

regards,

Hugo.
