Anybody know of a good (digital) PWM chip?
I have an app (motion control with a DMX lighting interface) where I have to control a lot of channels via PWM chopping. (far more than are available on any microcontroller)
In an ideal world, I need a 10 bit PWM chip with some sort of serial interface (I'm gonna daisy-chain them). I'd decode my DMX interface in one master controller and feed 32 channels out to the PWM chips
I know I could roll my own by programming a bunch of PIC's to do the function, but I'd like to minimize the number of programmed parts.
