code -200877

Hi guys, I'm a CVI beginner and I hope you will help me to fix a problem. I tried to continuosly acquire analog voltage signals from several channel, using DAQmxRegisterEveryNSamplesEvent statement as in "TDMS-ContAcq-IntClk" example. But sometimes I receive this error message:

"Requested  Every N Samples Event Interval is not supported for the given Data Transfer Mechanism and buffer size. To keep DMA or USB Bulk as the Data transfer mechanism, modify the buffer sizxe and/or the Every N Samples Interval. To keep the same Every N Samples Interval and buffer size, chenage the Data transfer mechanism to interrupts if supported. Property: DAQ_mx_Every N Samples Acq Into Buffer Event Interval.

Requested value: 1024

Buffer size: 1000

Status code:-200877"

So my question is : how can I change the buffer size and which criteria I can use to do it?

Thank you

See this discussion about that error.



Proud to use LW/CVI from 3.1 on.
