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?!!Unfortunately, DAQ_Check does not return the value of the most recent sample. Also, polling at 10 msec is of little use when you sample faster than this and need to know the most recent sample.
