It says that this VI will allocate 1 of 4 PWM generators. I'm guessing that means I can only have 4 of these in my Underglow_Control.vi? Maybe someone here who has used this control before can spread a little light on it?

Now I would use that handy WPI_PWMSetValue.vi, except that we only have 4 PWM channels free, plus the spacing and such between the PWM headers would make it more of a wiring hassle rather than just using the signal pins that I already have and using 1 PWM cable for each LED strip. Plus... we're using up 6 of the 10 PWM outputs, and we would rather not add an additional sidecar.

My only other idea is to combine both LED strips into 1 using a Y-cable and using 3 of the WPI_PWMSetValue.vi's unless I can truly use 6 of them (which I hope).

Let me know your thoughts, or if you have any questions about my project, just ask.

PWMSetValue will output a servo style PWM signal, which is not what you want for your LEDs. WPI_DigitalOutputGeneratePWM.vi is new this year, and you might not find anyone who's used it before. Don't be afraid to experiment.
