Help with PWM using sample "Gen Dig Pulse Train - Continuous"

[ChristianRoth]

I am using the provided sample in Labview 8 to output a PWM signal at the rate of 125HZ.  The problem comes into play when I need to dynamically update the duty cycle.  With the example I need to either stop the VI and start it again or retrigger.  If throw everything in a while loop the output waveform seems to over write itself.

I am jut looking to update the duty cycle dynamically either by osftware or a click of a mouse button.

Hi ChristianRoth,

Take a look at this tutorial; it addresses how to change the duty cycle dynamically. I hope it is helpful,
