Generate event for every N pulses from counter channel output

[viteo_sen]

Hi.

Im using counter channel output with finite samples to control step motor driver. For example, I generate 2500 samples per channel and step motor rotates for 2500 steps.

Now i want it to generate events (that will start analog measurments) while step motor is rotating. For example, every 200 samples i want event structure to start data aquisition subVI in parallel thread without stopping the motor.

how can i reach my aim? please help. thank you.

p.s. im using NI-6251 and NI USB-6366

Hi viteo_sen,

If you want to create custom event, you can create user event.

You can use DAQmx Events, http://www.ni.com/tutorial/5384/en/#toc3

Look at Every N Samples Transferred From Buffer Event
