Point me to the example make one pulse 6225 board + daqmx

Solved!
Go to solution

Looking for a white paper/examples defining the terms of DAQmx digital signals, for a trivial vi that runs by hand in MAX . All I'd like to do is use the PFI4 terminal on a pci-6225 to generate one 100us pulse. There are a variety of choices in generating a  pulse from PFI4 but my choices keep getting rejected at compile or run time as inappropriate for the mode selected. There must be examples like this, right ? I must not be searching the correct terms.

 

TIA

Alex

Hi Alex,

 

I came across this example on ni.com/examples: https://decibel.ni.com/content/docs/DOC-26277

My search terms were: labview single digital pulse

Mike -

Thanks but not the correct answer. I need to use Port 1/PFI4  of a 6225 , counter outputs are not an option with this hardware -ok,  while we are at it, this 6225 is already running analog in channels which take an external clock on PFI1. How do I figure out which digital types will let me make one pulse on PFI4 with an external clock  ?  Yes, change to a digital output type in the write task vi, but then, which kind of waveform and input....

As mentioned, I'm looking for the comprehensive document that can point to the different choices among hardware/tasks/types/setups so that one can set up a digital output without going through the trial-and-error of LV complaining about one thing or another at compile and run time. Fragmented documentation  of the various features has been frustrating over the  years that I've been an occasional LV user.  I appreciate your efforts.

Hi Alex,

 

The following link has some general info on configuring DAQmx applications: http://www.ni.com/white-paper/5468/en/

There's also some useful information contained in the help for the DAQmx Write VI: http://zone.ni.com/reference/en-XX/help/370469AA-01/lvdaqmx/mxwrite/
