PFI as an DI or DO? How to use DO sample clock?

[Leee]

Hi guys,

I want to use PFI as an DI and this as a trigger for another channel. By the way i am using all 8 DO P0.0:0.7 for DOs and using USB 6221

thanks in advance

Hey Leee,

you can find an example for this in the NI example finder:

Hardware Input and Output>DAQmx>Analog Measurements>Voltage>ContAcq-ExtClk-DigStart.prj

The command you need is:

DAQmxCfgDigEdgeStartTrig(gTaskHandle,triggerSource,triggerEdge)

I hope this helps.
