ta acquisition, when I ask DAQ_Monitor() for the newest ADC sample index, it returns only the odd number buffer indexes when they are available. However, the ADC buffer really does have all the data points in it. I'm using a PCI-6052. What's the deal?!!

In all our applications we create a seperate high priority thread to monitor the data acquistion, and poll it at 10ms intervals using DAQ_Check; this has provided the best performance for us as well.

Also, polling at 10 msec is of little use when you sample faster than this and need to know the most recent sample.

What's the deal?!!I am absolutely agree with the one already existing comment : I need data from my acquisition buffer during the acquisition and need the faster acquisition rates.
