In the past six weeks or so there was a post about suggestions to replace a lighting controller and someone responded that used to work for a company that did just that. One of the suggestions was to create a PWM DAC for each channel.
The OP just wanted a simple controller to control a lighting panel and that he threw away the old one because the rep was supposed to take care of the obsolete panel.
I can't seem to be able to find it by searching.
I just got an annoucement about a 48 channel cascadeable PWM DAC from LT that would probably be perfect for the guys application. It is here: https://www.electro-tech-online.com/custompdfs/2011/11/8500f.pdf
Now the hard part, would be to say interface a say bunch of rotary encoders to the individual or multiple channels. I'd almost consider creating a capacitance touce sensor for the encoder and only deal with that particular channel. I'd make sure the encoders used a direction/pulse tag and go from there.
I tried. If anyone can find the thread, I'm sure the OP would be grateful.
