Just to point out that the little circuit I pointed out earlier basically acts like a PWM-controlled potentiometer, so can control any voltage up to the chip max and need not share a ground with the logic side. It can be especially useful for such as the KBIC speed controls where the pot floats at +100V relative to machine ground. (The circuit will still work as the optical link is good to 1000s of volts, and the actual voltage across the pot terminals is only 10v). -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
