I am making a real time program in a daq at mio 16e 10. I need a continous scanning every 1,66 or 2 ms.(only 1 channel).I am using "AI Sample Channel" inside a for loop.
Sampling is controlled by a "Wait Until Next ms Multiple" but it has 1 ms. accuracy.
How can I solve that?
Is there a higher-accuracy clock?
I do not use buffered scanning because I can not lose any sample.
My adquisicion board does not support multi-buffered scanning.
labview version 5.01
daq at mio 16e 10

Using high-level software for timing the time between scans in these kind of freqs is useless.

I always thought that the double-buffer mechanism was strictly an NI-DAQ thing, not something your board has to take care of by using hardware buffers.
It could be your old board is no longer supported by a recent NI-DAQ version, but old version should not be bad for your application. Just try the double-buffering and regularily read-in the new values (don't know the details, it has been a while since used last).

There is a very well documented knowledge base that answers your question. The trick is to use AI Single Scan. The knowledge base can be found at the following link:
