PWM

[krick14]

Someone can help me make a PWM signal using a saw waveform and a DC signal in labview, is the first time I go to use it and I have no idea how.
I am using Labview 2012, there would be no problem in using it in previous versions???

I typed "PWM" at the example finder and there's some examples.

Take a loot at them and see if it helps (don't forget to check the description for each example).

Hi krick.

In addition to what joaopam said, you can simply compare the current value of the saw tooth waveform with the DC value, and depending on whether it's lower or greater send the value to True or False, then output this value with your hardware (DAQ, cRIO, etc).

As for the LabVIEW versions. You can't run it normally with previous versions, but you can select File: Save for Previous Version... and select the version you will open it with. You can open older LabVIEW files with newer versions as long as there isn't a huge gap between versions.

For example, LabVIEW 2012 can open VI's created in versions 8.0 and up.
