Prop-2 PWM 0-5v?

Jon,

Is it possible using the header pins on the Prop-2 to get a 0-5 v output? I am working with the manufacturer of some high power led lighting, and they can be brightened and dim with a 0-5 input on their driver.

You cannot get analog directly out -- requires some sort of D-to-A conversion.  Interestingly, that's what the PWM command was intended to do: you can use it to charge an RC circuit to a specific voltage.  If the impedance of the device you're using is high enough you can use just an RC (10K + 0.1); what I suspect you'll need, though, is a buffer like this:
