How to Read Value of DAC on PXI-7853R

[sockanasa]

This seems so basic, but I can't find help on it.  I have an NI-RIO PXI-7853R FPGA DAC output that is being set.  How can I querry to find the value it is set to or even better the buffer values for the DAC?  I do not want to have to write to a shared variable every time the value changes and likewise, read a shared value each time I want to know it.  It would be easier to use an FPGA IO property mode I can just read or something along those lines.  Suggestions?

Hi sockanasa,

There's no way of querying the value of an analog output.  Is there a reason that you need to be able to read from the analog output.  Local variables that hold the last values written would probably be best.  Here's a good discussion of tracking the value of analog output: http://forums.ni.com/ni/board/message?board.id=170&message.id=469995&requireLogin=False.
