Does anyone have any success stories involving CPU-based slaves and "real"
networks, and if so, on what platforms (and what clock speeds)?
Many years ago (as in almost a decade now), several of us out here
implemented a slave on a PIC16F628 to interface a Sensirion SHT75 with
1-wire. We kept fairly quiet about it, as at that point Maxim/Dallas
wasn't being overly friendly towards non-licensed slaves (and one of us
doing the implementing was a design engineer for Maxim). It was almost
certainly clocked at 20MHz, just because that's what we were using on
everything else at the time.
I can't promise I still have the source code, but I'll dig around and see
if you're curious. It's written in PIC assembler however, so it would be
almost useless if you're trying to implement on an AVR.
