DAQmx read without waiting for buffer refill

Hello,

I am using the continous acquisition mode and want to read at any time the 50 latest values out of the buffer without waiting for refilling.

I have found no setting to do this, the DAQmx read function is always waiting until the buffer is filled with the next 50 values.

Of course I could set the buffersize to 1 and read every single value, but that would be very time consuming.

Best regards,

Metin
