How can I implement precise digital pulses width +/-0.1ms or less in LabView using Analog discovery 2?

[ysrevol]

I am a beginner in labview and python.

I implemented a pulse on digital IO 0:1 using Labview using Analog discovery 2.

However, the change in pulse width was about +/-0.8msec. If there are any methods or related examples that can implement a precise pulse width (+/-0.1ms or less) with labview, please Let me know them.

Hi @ysrevol

With the C API, see WF SDK/ samples/ py/ DigitalOut_Pulse.py

Thank you very much for the good information.

However, I am a beginner in labview, so it is difficult to apply it right away.

It would be very helpful if you could upload a simple labview example that includes the DigitalOut_Pulse.py Python file you mentioned.

Thank u~

Hi @ysrevol

You could import the WF (SDK) C API in LabVIEW, or write a custom app or library which controls the device and call this from LV.

Thank you for your great information. I am a complete beginner in LV, and I have never imported WF (SDK) before. So, if possible, it would be of great help if you could give me just one related example that imports DigitalOut_Pulse.py.

I found a good site that generates PWM waveforms.

Considering my level, I need a simple "getting start", but ^^ I think this site will help a lot.
